Please provide and example of how you would use the client side event handlers to allow the user to press the enter key to add a a new line to the text.  Changing the textmode to Multiline just allows for WRAPPING, which is NOT the same as true multi-line editing.  The fact that the editor doesn't support or allow true multi-line editing (with the user able to add multiple lines by hitting the enter key) is absurd.  If you are going to propose a work around to your products gross limitations, please have the courtesy to provide an example of how you would implement such a work around for such a basic missing feature.

Praveena,

In IE8, the following updated WebDataGrid1_Initialize event handler will correct the issue:

function WebDataGrid1_Initialize(sender, eventArgs) {
    var editor = document.getElementById("SiteEditor");
    editor.onkeydown = function (e) {
        if (e == null)
            e = event;
        // don't cancel the event if the backspace or delete key was pressed.
        if (e.keyCode == 8 || e.keyCode == 46)
            return true;
        // cancel the event if the length of the editor is 4 or more.
        if (editor.value.length >= 4)
            return false;
    };
}

When I tested in Firefox and Chrome I was only able to enter up to four characters.

Let me know if you have any questions with this matter.

Hi,

No it is not working, it is giving the error as "Microsoft JScript runtime error: 'null' is null or not an object" in the javascript on the page load itself i.e. on the first time run itself.

Can we able to do this in the "onkeypress" event.  because when I tried this "onkeypress" in the TextBoxProvider. it is not accepting this event and it is giving the error.

Thanks.

Praveena,

When you are debugging this, what specifically is null?

Hi,

It is giving the error in the javascript itself in the below code .

editor.onkeydown = function (e) {       

  if (e == null)       

      e = event;   

      // don't cancel the event if the backspace or delete key was pressed.       

  if (e.keyCode == 8 || e.keyCode == 46)      

       return true;    

     // cancel the event if the length of the editor is 4 or more.    

    if (editor.value.length >= 4)       

      return false;

Praveena,

Using the Visual Studio debugger or the debugger built into IE8, please find exactly what line the script is failing on and what is null and let me know what you find.

Let me know if you have any questions with this matter.

Hello Praveen,

Please let me know if I can provide any further assistance regarding this matter.

Hello Praveen,

To prevent the cell from existing edit mode when tab is pressed, Webdatagrid's  KeyDown and cell exiting edit mode clients side events needs to be handled like below

function WebDataGrid1_Grid_KeyDown(sender, eventArgs)

{   var editedColumn = "";
    if (sender.get_behaviors().get_editingCore().get_behaviors().get_cellEditing().get_cellInEditMode() != null ) {
        editedColumn = sender.get_behaviors().get_editingCore().get_behaviors().get_cellEditing().get_cellInEditMode().get_column().get_key();
    }
    if (editedColumn == "Name") {
        if (eventArgs.get_browserEvent().keyCode == 9 || eventArgs.get_browserEvent().keyCode == 13) { 
            eventArgs.set_cancel(true);
}}}
function WebDataGrid1_CellEditing_ExitingEditMode(sender, eventArgs)
{
    if (eventArgs.getCell().get_column().get_key() == "Name") {
        if (eventArgs.get_browserEvent().keyCode == 9 || eventArgs.get_browserEvent().keyCode == 13) {      
            eventArgs.set_cancel(true);
}}}

Attached sample demonstrates the same.

Hello Praveen,

The have tried to cancel the event when the tab key is pressed but the cell is exiting from the editmode. So, I am currently discussing with our Development team regarding this matter and I will update you by the end of the day tomorrow with the progress.

Please let me know if you have any further questions regarding this matter

Hi,

Like a multiline when the tab key is pressed inside the particular column cancel the event and it should work as a tab in the notepad.

Please do the needful.

Thanks in Advance.

Hello Praveena,

I would recommend you to use TextEditorProvider as shown below:

<EditorProviders> <ig:TextEditorProvider ID="WebDataGrid1_TextEditorProvider1"> <EditorControl ClientIDMode="Predictable" MaxLength="4" MultiLine-Rows="4" TextMode="MultiLine"> </EditorControl> </ig:TextEditorProvider> </EditorProviders>

This will limit number of character to 4, It is not needed to write any custom code.

I hope this helps.
