Hello,

I have a page which has a webtab control on it.  There's about 5 tabs on it, and the rightmost one has a usercontrol on it.  this control consists of a GridView and a couple of ASP:Buttons on it.  The problem I am having is this:  I have an imagebutton control inside the Gridview which has a databound CommandArgument set from a datarow item.  This control works normally outside of the WebTab, and the gridview's RowCommand event fires normally with the right CommandName/CommandArgument.  However, once the usercontrol is tossed into a WebTab control, when I click on the imagebutton the page posts back, but the RowCommand event never fires (Using VS2008 debugger with a breakpoint set on the handler).

Is there any particular reason this might happen?
