Function

void _loadUrl(object o, string url)

The function loads the page defined by the “url” parameter using an asynchronous ajax call, resp. loads the HTML code of this page. The function does not wait for a response from the server, after calling it, the execution of javascript code continues. The “o” parameter is an auxiliary object in which all the information needed to successfully complete an asynchronous ajax call is stored, and this object can be anything in the object model of the website or a newly created object. Only one asynchronous call can be called at a time using one object. If the “_loadUrl” function is called again with the same helper object for which the asynchronous call has not yet been completed, a new asynchronous call will not occur. If a parallel call to the “_loadUrl” function is required, it is ideal to select “new Object()” as the auxiliary object “o”.

Example:

var p0 = 'ěščřžýáíé', p1 = 'ĚŠČŘŽÝÁÍÉ';
_loadUrl(new Object(), 'ngef.aspx?MyFirstFunction,' + urlEncode(p0) + ',' + urlEncode(p1));

void _loadUrl(object o, string url, string f)

The function loads the page defined by the “url” parameter using an asynchronous ajax call, resp. loads the HTML code of this page. The function does not wait for a response from the server, after calling it, the execution of javascript code continues. When the answer then arrives, the execution of the main context of the code is suspended (sooner or later depending on the priority of the performed task) and the so-called callback defined by the “f” parameter. The resulting HTML code of the page is passed to the “f” function as the first parameter. The “o” parameter is an auxiliary object in which all the information needed to successfully complete an asynchronous ajax call is stored, and this object can be anything in the object model of the website or a newly created object. Only one asynchronous call can be called at a time using one object. If the “_loadUrl” function is called again with the same helper object for which the asynchronous call has not yet been completed, a new asynchronous call will not occur. If a parallel call to the “_loadUrl” function is required, it is ideal to select “new Object()” as the auxiliary object “o”.

Example:

function ajaxTest()
{
var p0 = 'ěščřžýáíé', p1 = 'ĚŠČŘŽÝÁÍÉ';
_loadUrl(new Object(), 'ngef.aspx?MyFirstFunction,' + urlEncode(p0) + ',' + urlEncode(p1), ajaxResponse);
}

function ajaxResponse(html)
{
alert(html);
}

for (var i = 0; i < 5; i++)
{
ajaxTest();
}

void _loadUrl(object o, string url, string f, string id)

The function loads the page defined by the “url” parameter using an asynchronous ajax call, resp. loads the HTML code of this page. The function does not wait for a response from the server, after calling it, the execution of javascript code continues. When the answer then arrives, the execution of the main context of the code is suspended (sooner or later depending on the priority of the performed task) and the so-called callback defined by the “f” parameter. The resulting HTML code of the page is passed to the “f” function as the first parameter. The optional parameter “id” is passed to the “f” function as the second parameter. The “o” parameter is an auxiliary object in which all the information needed to successfully complete an asynchronous ajax call is stored, and this object can be anything in the object model of the website or a newly created object. Only one asynchronous call can be called at a time using one object. If the “_loadUrl” function is called again with the same helper object for which the asynchronous call has not yet been completed, a new asynchronous call will not occur. If a parallel call to the “_loadUrl” function is required, it is ideal to select “new Object()” as the auxiliary object “o”.

Example:

function ajaxTest(id)
{
var p0 = 'ěščřžýáíé', p1 = 'ĚŠČŘŽÝÁÍÉ';
_loadUrl(new Object(), 'ngef.aspx?MyFirstFunction,' + urlEncode(p0) + ',' + urlEncode(p1), ajaxResponse, id);
}

function ajaxResponse(html, id)
{
alert(id + ': ' + html);
}

for (var i = 0; i < 5; i++)
{
ajaxTest(i);
}

void _loadUrl(object o, string url, string f, string id, string params)

The function loads the page defined by the “url” parameter using an asynchronous ajax call, resp. loads the HTML code of this page. The function does not wait for a response from the server, after calling it, the execution of javascript code continues. When the answer then arrives, the execution of the main context of the code is suspended (sooner or later depending on the priority of the performed task) and the so-called callback defined by the “f” parameter. The resulting HTML code of the page is passed to the “f” function as the first parameter. The optional parameter “id” is passed to the “f” function as the second parameter. The parameter “params” is sent together with the asynchronous call by the POST method, and it is a list of key vs. pair pairs. value separated by a “&amp;” character. The “o” parameter is an auxiliary object in which all the information needed to successfully complete an asynchronous ajax call is stored, and this object can be anything in the object model of the website or a newly created object. Only one asynchronous call can be called at a time using one object. If the “_loadUrl” function is called again with the same helper object for which the asynchronous call has not yet been completed, a new asynchronous call will not occur. If a parallel call to the “_loadUrl” function is required, it is ideal to select “new Object()” as the auxiliary object “o”.

Example:

function ajaxTest(id)
{
var p0 = 'ěščřžýáíé', p1 = 'ĚŠČŘŽÝÁÍÉ';
_loadUrl(new Object(), 'ngef.aspx?MyFirstFunction', ajaxResponse, id, 'p0=' + urlEncode(p0) + '&p1=' + urlEncode(p1));
}

function ajaxResponse(html, id)
{
alert(id + ': ' + html);
}

for (var i = 0; i < 5; i++)
{
ajaxTest(i);
}

void attachEvent2(object o, string type, function listener)

The function appends the “listener” function to the “o” object event. “Type” defines the type of event, eg load, scroll, etc.

Example:

attachEvent2(window, 'load', function () { alert('onload1'); });
attachEvent2(window, 'load', test);

function test()
{
alert('onload2');
}

void bt_Click()

The function invokes the form reload (postback). During this event, the data of all tables, calendars, graphs, etc. will be reloaded. This function has been replaced by the “form_Update” function.

Example:

bt_Click();

void bt_Click(string id)

The function triggers a program click on the button specified by the “id” parameter. The function first tries to find an element with the given ID, and if it can't find it, with the given text.

Example:

bt_Click(BT123);
bt_Click('Save');

bool bt_Eval(object bt, string url, string f)

When the button is pressed, the function loads the page (typically an external function) defined by the “url” parameter, and uses the validating function defined by the “f” parameter to verify the loaded HTML code. The validating function must return a logical value of “true” or “false”, which determines whether to continue processing the “onclick” event. The behavior of the “bt_Eval” function can be defined when specifying the JavaScript of the button (see figure). And also in the javascript of the relevant view page or edit form.

Example:

1st variant:
return bt_Eval(this, 'ngef.aspx?test', 'evalFunction');

2nd variant:
return bt_Eval(this, 'ngef.aspx?test', ajaxResponse);

function ajaxResponse(html)
{
return confirm('Response: ' + html);
}

3rd variant:

return test(this);

function test(bt)
{
if (!bt_Eval(bt, 'ngef.aspx?test', ajaxResponse)) return false;
return confirm('Continue?');
}

function ajaxResponse(html)
{
return confirm('Response: ' + html);
}

object bt_FindByText(string text, int index)

The function returns a button with the title specified by the “text” parameter. The “index” parameter is optional and tells you how many times the button with the title “index” should return the function. This parameter is important in edit forms where multiple buttons with the same title are located. Numbering is from zero, so the first button has an index of 0.

Example:

var bt = bt_FindByText('Today', 2); // Returns a button object that is named “Today” and is third in the form with that name

bool bt_Icon(object bt, string url)

The function sets the image defined by the “url” parameter in the background of the button.

Example:

bt_Icon(el(BT123), 'Images/MD/Content/ic_add_white_18dp.png');

void button_Disable(o)

The function disables the button specified by the “o” parameter in the edit form.

Example:

button_Disable(BT123);

void buttons_Disable()

The function disables all buttons in the edit form.

Example:

buttons_Disable();

void button_Enable(o)

The function enables the button specified by the “o” parameter in the edit form.

Example:

button_Enable(BT123);

void buttons_Enable()

The function enables all buttons in the edit form.

Example:

buttons_Enable();

void cb_Disable(object cb)

The function disables the editing of the “ComboBox” control specified by the “cb” parameter. An alternative is the general function “control_Disable”.

Example:

cb_Disable(#ng_combobox#);

void cb_Enable(object cb)

The function enables editing of the “ComboBox” control specified by the “cb” parameter. An alternative is the general function “control_Enable”.

Example:

cb_Enable(#ng_combobox#);

string Color2Hex(string value)

The function formats the color specified by the “value” parameter into hexadecimal from the input format “R,G,B”.

Example:

var s = Color2Hex(control_GetValue(#ng_color#));

void control_Disable(object o)

The function disables editing of the control defined by the “o” parameter.

Example:

control_Disable(#ng_control#);

void control_Disable(object o, bool disableLink)

The function disables editing of the control defined by the “o” parameter. The optional “disableLink” parameter (true/false) determines whether the reference to the selected record is to be deactivated for the “ForeignKey” control.

Example:

control_Disable(#ng_control#);
control_Disable(#ng_control#, false);

void control_Enable(object o)

The function enables editing of the control defined by the “o” parameter.

Example:

control_Enable(#ng_control#);

string control_GetValue(object o)

The function returns the value of the database control specified by the “o” parameter. The value of the control can also be found simply using the notation “#ng_control#.value”, but this notation cannot be used for the following controls:

  • TextBox of type Date with time on – the time is placed in a different text field than the date itself, so “#ng_textbox#.value” returns only a date folder without time, the only possible way to return the date and time is “control_GetValue(#ng_textbox#)”
  • MultiListBox – the only possible way to return a tab-delimited list of selected values is “control_GetValue(#ng_multilistbox#)”
  • Radio – the only possible way to return the selected value is “control_GetValue(#ng_radio#)”
  • CheckBox – next to the function “control_GetValue(#ng_checkbox#)”, which returns a text value stored in the database if the button is checked, or an empty text string if the button is not checked, it is possible to use the logical value “#ng_checkbox#.checked”, which returns a check/do not check the button

Example:

var s = control_GetValue(#ng_control#);

void control_ResizeTable(object o, int width)

The function sets the width of the table in which the control specified by the “o” parameter is displayed to the new width specified by the “width” parameter.

Example:

control_ResizeTable(#ng_control:Table#, 60);

void control_Save(object o)

The function stores the value of the database control in the database using ajax. “OnBeforeSave” and “OnAfterSave” events are not executed when saved. The “o” parameter specifies the database control whose value will be stored in the database.

Example:

control_Save(#ng_control#);

void control_Save(object o, string f, string errorMessage)

The function stores the value of the database control in the database using ajax. “OnBeforeSave” and “OnAfterSave” events are not executed when saved. The “o” parameter specifies the database control whose value will be stored in the database. The “f” parameter specifies the name of the function to run after the response is retrieved from the server. This response is either “OK” (record saved) or “ERROR” (record failed). The “errorMessage” parameter defines the text of the error message that is displayed if an error occurs during saving.

Example:

control_Save(#ng_control#, ajaxResponse, 'An error has occured');

function ajaxResponse(status)
{
alert(status);
}

void control_SetValue(object o, var value [, var value2])

The function inserts the value defined by the “value” parameter into the database control specified by the “o” parameter.

  • If it is a “TextBox” with “Date” or “DatePicker” validation, it is possible to use the “value” parameter as a text string formatted in the form “dd.MM.yyyy HH:mm”, or a javascript object of the “Date” type. The “value2” parameter is optional and specifies the time in the format “HH:mm”. The parameter is only relevant for “TextBox” with “Date” validation and selected time entry.
  • If the “value” parameter is a javascript object of the “Date” type, it is not necessary to specify the “value2” parameter, NET Genium will automatically read the time data from the “value” parameter.
  • If it is a “CheckBox”, it is possible to use two types of “value” parameters:
    • If the “value” parameter is a logical value, it is said whether to check the check box or not.
    • If the “value” parameter is a text string, its value will first be compared with the value set in the control's properties, and depending on the result of this test, the check box will be checked or not.

Example:

control_SetValue(#ng_control#, 'Text');
control_SetValue(#ng_textbox#, 20);
control_SetValue(#ng_textbox#, '1.1.2000');
control_SetValue(#ng_textbox#, '1.1.2000', '12:34');
control_SetValue(#ng_textbox#, new Date());
control_SetValue(#ng_datepicker#, '1.1.2000');
control_SetValue(#ng_datepicker#, '1.1.2000 12:34');
control_SetValue(#ng_datepicker#, new Date());
control_SetValue(#ng_checkbox#, true);
control_SetValue(#ng_checkbox#, 'x');
control_SetValue(#ng_foreignkey#, 20);

void controls_Disable()

The function disables editing of all controls (except buttons) in the edit form.

Example:

controls_Disable();

void controls_Disable(bool disableLinks)

The function disables editing of all controls (except buttons) in the edit form. The optional “disableLinks” parameter (true/false) determines whether the reference to the selected record is to be deactivated for the “ForeignKey” controls.

Example:

controls_Disable();
controls_Disable(false);

void controls_Enable()

The function allows editing of all controls (except buttons) in the edit form.

Example:

controls_Enable();

void controls_Join(object[] array)

Example:

controls_Join([#ng_control1#, #ng_control2#, #ng_control3#]);
controls_Join(new Array(#ng_control1#, #ng_control2#, #ng_control3#));

void controls_Save(object[] array)

The function stores the values of database controls in a database using ajax. “OnBeforeSave” and “OnAfterSave” events are not executed when saved. The “array” parameter specifies a list of database controls whose values will be stored in the database.

Example:

controls_Save([#ng_control1#, #ng_control2#]);
controls_Save(new Array(#ng_control1#, #ng_control2#));

void controls_Save(object[] array, string f, string errorMessage)

The function stores the values of database controls in a database using ajax. “OnBeforeSave” and “OnAfterSave” events are not executed when saved. The “array” parameter specifies a list of database controls whose values will be stored in the database. The “f” parameter specifies the name of the function to run after the response is retrieved from the server. This response is either “OK” (record saved) or “ERROR” (record failed). The “errorMessage” parameter defines the text of the error message that is displayed if an error occurs during saving.

Example:

controls_Save([#ng_control1#, #ng_control2#], ajaxResponse, 'An error has occured');

function ajaxResponse(status)
{
alert(status);
}

If the insert is not successful, the function returns “false”.

Example:

copyToClipboard('Value to be pasted into clipboard', 'Value successfully pasted into clipboard.');

string Date2Str(object date)

The function returns a text string in the format “dd.MM.yyyy HH:mm” from the date specified by the “date” parameter. If the time is 00:00, the function returns only a string in the format “dd.MM.yyyy”.

Example:

var s = Date2Str(new Date());

void ddl_ReplaceTexts(object ddl, object array, string separator)

The function replaces the texts of the items in the drop-down list specified by the “ddl” parameter with the values defined in the “array” field. The field must contain the value that is stored in the database and the placeholder text that you want to appear in the drop-down list instead of the value. The last parameter “separator” is optional, and acts as a separator between the value and its placeholder text. Replacing texts with this function does not affect the value that is stored in the database.

Example (requires ComboBox control with items 1, 2 and 3):

var array = new Array();
array[0] = new Array('1', 'First item');
array[1] = new Array('2', 'Second item');

This javascript function is always executed when a script interrupt is called in the edit form or on the view page. The interrupt text is passed to the “value” parameter as set in the script designer. To easily identify the type of interrupt, it is recommended to add, for example, a numeric code to the text of the interrupt, and then try to find this code in javascript. The javascript function “script_Error” must be defined as a whole in the edit form or on the view page, i.e. including “function script_Error(value)”.

Example:

Interruption “Error occurred(123)”

function script_Error(value)
{
if (value.indexOf('(123)') != -1)
{
// ...
}
}

void scroll_To(int x, int y, bool save)

The function scrolls the edit form or view page to the position defined by the “x” and “y” parameters. The optional “save” parameter means that this position should be remembered immediately, usually when the “scroll_To” function is called by the server script button.

Example:

scroll_To(0, 0, true);

void setTimeout2(object o, function f, int timeout)

The function calls another function defined in the “f” parameter after the time period defined in the “timeout” parameter has elapsed. The function always binds to the specific object specified by the “o” parameter. If the “setTimeout2” function with the same parameters is called again during the specified time period, the previous call is canceled and a new one is scheduled again after the time period defined in the “timeout” parameter has elapsed. The value of the “timeout” parameter is given in milliseconds.

Example:

var saveObject = new Object();

function form_Change()
{
setTimeout2(saveObject, function() { form_Save(); }, 1000);
}

void tb_InitAjax(object tb, function f, int width, int left, bool focus)

The function initializes its own ajax picker, which is defined in the external function “ngef”. The control for which the picker will be initialized is defined by the “tb” parameter. The “f” parameter defines the function that will be used to load the picker. The “width” parameter specifies the width of the picker in pixels. The “left” parameter determines the displacement of the picker window on the x-axis with respect to the location of the respective control. The “focus” parameter determines whether the picker is to be displayed when the control is clicked (true) or when entering data (false).

Example of the client part:

tb_InitAjax(#ng_tb#, function(e) { startSearch(e, 'test1', 'test2'); }, 150, 0, false);

function startSearch(e, p0, p1)
{
// tb_LoadUrl(e, 'ngef.aspx?TestPicker,' + urlEncode(#ng_tb#.value) + ',' + p0 + ',' + p1);
tb_LoadUrl(e, 'TestPicker.aspx?' + urlEncode(#ng_tb#.value));
}

Example server part (source code of TestPicker.aspx):

StringBuilder sb = new StringBuilder();

DataTable data = new DataTable();
data.Columns.Add("value");

for (char ch1 = 'A'; ch1 <= 'C'; ch1++)
for (char ch2 = 'A'; ch2 <= 'C'; ch2++)
for (char ch3 = 'A'; ch3 <= 'C'; ch3++)
{
data.Rows.Add(ch1.ToString() + ch2.ToString() + ch3.ToString());
}

DataView view = new DataView(data, args[0].Length != 0 ? "value LIKE " + ParserSql.ToString(args[0], true, true,
DbDriver.DataView) : "", "value", DataViewRowState.CurrentRows);
int n = 0;

foreach (DataRowView row in view)
{
if (n == 20)
{
sb.Append("<br>...");
break;
}

if (sb.Length != 0) sb.Append("<br>");

sb.Append("<a class=\"lf\" = '");
sb.Append(row[0]);
sb.Append("'; return false;\">");
sb.Append(row[0]);
