Update/Cancel not working in UserControl in Grid

[russ]

I have a RadGrid that implements a web user control for the edits.  I've attempted to follow replicate as much as I could from the demo at http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/usercontroleditform/defaultcs.aspx but for some reason, my buttons aren't kicking off the update command on the RadGrid.  I had all of the data populating, but started over so now I only have a couple of the items populating on the user control.  All I'm concerned with right now is getting the btnSubmit to work.. I imagine that after I get that working, I'll be able to get the rest of them working

Another thing that I forgot to mention, I am using methods in another method class to get the data, and to attempt to update it.  Or at least that's how I want to do it.

please disregard.  I had the grid setup to populate through the page_load method.  I moved that code to the needsource method, and the update command seems to be working now.
