When I click cancel on my custom advanced from, the page load runs and the form creating and created get called again.  It then runs all of my form created code before it dismisses the popup. 

If I can check the commandName on this link button, I could fix this easily. 

<asp:LinkButton runat="server" ID="btnCancel" CssClass="rsAdvEditCancel" CommandName="Cancel" CausesValidation="false">

Ideas?

Hello,

Indeed the "Cancel" button in the RadScheduler advanced form is performing a post-back when closing the form. Here you may find a similar forum post that provides a sample project demonstrating how you can hide the advanced form without performing any post-back.
I would like to note that this functionality is only implemented in the AdvancedEditForm for sample purposes. So if you want to test it, please try to modify an existing appointment and click the cancel button placed in the pop-up form.
