RadContextMenu Cancel Postback from OnContextMenuClick javascript event

[Tuhin Ghosh]

Hi,

I have created following context menu:

<telerik:RadContextMenu OnClientShowing="OnContextMenuShowing" OnClientItemClicked="OnContextMenuClick"
                  ID="RadMenu1" runat="server" OnItemClick="RadMenu1_ItemClick" EnableRoundedCorners="true"
                  EnableShadows="true">
                  <Items>
                    <telerik:RadMenuItem Text="Copy" />
                    <telerik:RadMenuItem Text="Cut" />
                    <telerik:RadMenuItem Text="Paste Above" />
                    <telerik:RadMenuItem Text="Paste Below" />
                  </Items>
                </telerik:RadContextMenu>


OnContextMenuClick I am writing some validation and I want to cancel the postback if validations fails, but its not happening.

I have searched everywhere but did not find any suitable answers for this , many places I found the following statement but it is not working 

args.set_cancel(true);

args in OnContextMenuClick does not have set_cancel method.

Also tried with return false; that too not worked.

Please help me by providing solutions its urgent.


Thanks & Regards

Hello Tuhin,

You cannot cancel the OnClientItemClicked event so try the same in OnClientItemClicking and cancel the event.
Javascrupt:

<script type="text/javascript">
    function OnClientItemClicking(sender, args)
     {
        var item = args.get_item();
        if (item.get_text() == "Cut")
        {
            args.set_cancel(true);
        }
    }
</script>

Thanks,
Shinu.
