I've searched and search and can't quite find an example like I'm looking for. Here's my situation and I'll keep it as simple as possible:
I have a RadToolbar and a user control on a page. The user control has a RadGrid in it. When I click a button on the RadToolbar, I want to ajaxify the user control (no screen flash / reload). The grid gets populated in the NeedDataSource() event by pulling it's data from a session variable that was populated in the button click event.. Really all I need to know is how to wire this up. If a simple example could be provided, that would be great. Like I already said, I've searched the forums, online demos, & help file.
Thanks,
Rob

OK, here's the code to provide a starting point. I simplified the scenario even more by just using an <asp:button> instead of a RadToolbar.
What I'm noticing is, the first time I click the button nothing happens. The 2nd time I click the button, I get my desired results. How do I get it to work on the first click?

I could really use some help on this.

Hi Dudeman,
In order the grid to display the data you are retrieving on a button Click, you need to explicitly rebind it. Please find attached a sample project illustrating the above suggestion and let me know if it works for you.
