Problems with Delete key on grid

[Ralph]

Hi,
 
My grid has EditMode="Batch"
 <BatchEditingSettings EditType="Row" />

And AllowKeyboardNavigation="true"

Pressing Delete key causes JavaScript errors when no rows are selected.  This happens right after a row was deleted.

I was trying to disable this key through,
       

$(document).keydown(function (e) {
   if (e.which == 46) {
      e.preventDefault();
      return false;
   }
});

This prevents  Delete key from functioning, but only when focus is inside edited textbox. 

When a row is highlighted, the code executes, but a row is deleted anyway.  Setting AllowKeyboardNavigation to false resolves this issue at a loss of other functionality.

Is there a way to disable just the Del key?

Hello Ralph,

For cross-browser handling of this requirement you will have to use the following approach for canceling the keydown event:

<telerik:RadCodeBlock runat="server">
    <script type="text/javascript">
        function gridKeyDown(event) {
            if (event.keyCode == 46) {
                cancelRawEvent(event);
                event.keyCode = 0; //IE fix
            }
        }

        function cancelRawEvent(e) {
            var evt = e ? e : window.event;
            if (evt.stopPropagation) evt.stopPropagation();
            if (evt.preventDefault) evt.preventDefault();
            if (evt.cancelBubble != null) evt.cancelBubble = true;
            if (evt.stopImmediatePropagation) evt.stopImmediatePropagation();
            evt.returnValue = false;
        }
    </script>
</telerik:RadCodeBlock>

<telerik:RadGrid ID="RadGrid1" runat="server" OnNeedDataSource="RadGrid1_NeedDataSource" onkeydown="gridKeyDown(event);">
    <MasterTableView EditMode="Batch" BatchEditingSettings-EditType="Row">
    </MasterTableView>
    <ClientSettings AllowKeyboardNavigation="true">
        <Selecting AllowRowSelect="true" />
    </ClientSettings>
</telerik:RadGrid>

Please give this a try and see if it works as expected on your end.
