Hi,

This can be achieved using your custom button control in the transformation.

Example code:

<%@ Register Src="~/mycontrols/button.ascx" TagName="Button" TagPrefix="uc1" %>
<uc1:Button ID="button1" runat="server" />

Then you can perform button events in the file ~/mycontrols/button.ascx.cs.

Best Regards,
