OnClientSplitButtonClicking - cancel selection

[Karl Maynard]

I have implemented an OnClientSplitButtonClicking event handler on the client side, usign this i can call set_cancel(true) which prevents the button click event being fired.

However, it is still selecting the button as the selected button in the ribbonbar - i.e. it still updates the selected index of the split button itself.

Any ideas on how can i prevent this ?

I have tried adding client side handlers for OnClientButtonClicking, OnClientButtonToggling and OnClientSplitButtonClicking - but nothing else seems to allow me to cancel this.

Currently, i am having to reset the selection manually:

function OnSplitButtonClicking(sender, args) {
     args.set_cancel(true);

     var splitButton = findSplitButton("spbActions");

     if (splitButton != null)
       setTimeout(function () { splitButton.set_selectedButtonIndex(0); }, 0);

}

Hi Karl,

I tested the issue that you describe and indeed it is a bug of the RadRibbonBar control when canceling the server side event. We have already fixed it and the fix will be available with the internal build next week. You can also find your Telerik point updated.

Kind regards,

Hi Kate,
I do agree that this was a bug, however we were using the set_cancel on this event to stop a postback from triggering in the previous release.
Since upgrading we have had to use code very similar to what Karl posted in order to reset the value after cancelling the event.

Is there a way of cancelling the postback but not the event?

Thanks,
Matt

Hello Matt,

Unfortunately we are not aware of such workaround that will enable you to cancel the post back and at the same time be able to execute the following events when using the set_cancel(true). However, we will appreciate it very much if you come up with a possible solution and share it with us.
