I've recently upgaded to Visual Studio 2012 and RadControls ASP.NET AJAX Q1 2013.
Now all of my expand collapse columns in my grids have stopped working. When I click on the expander, it posts back, but does not expand.
Was something changed with the hierarchical grid scheme?

FYI, I have backed off to the Q3 2012 RadControls, and my grid expanders now work fine again. Something in the Q1 2013 controls doesn't play nicely with the expanders!

We have reported exactly the same issue, has Yours been solved ?
We can't reproduce it in separate project so it is difficult to show the support where it goes wrong.

Short answer: No. Something in the functionality of Q1 2013 RadControls changed, and broke all of my grids with row expanders. My old code had grid_NeedDataSource logic where I bound the grid DataSourceID to a stored procedure with one or more select parameters. This coding no longer works for Q1 2013. (I think the stored procedure would still work if it had no parameters.)
Telerik support replied: After consulting with our developers the scenario proved to be an invalid one. It seems that using both advanced data-binding and assigning data source controls to RadGrid is not supported and will not work in all cases.
So, I ended up having to recode all of my NeedDataSource methods and bind the grid to a DataSource = a DataTable that is filled via a
SqlDataAdapter.

I'm having the same problem.
My expand and collapse column doesn't seem to do anything when I click it.
If I set the Master Tables "HierarchyDefaultExpanded" to true, then I can see all the details. So I don't think the data sources are incorrect..
Please can someone help?
I'm running v2013.2.611.40

I managed to solve it for me!!
I was setting the connection string in the Page_Load event. I have to move this to the Page_Init event for it to work correctly. This worked before but after updating it stopped working.
I can still set the parameters dynamically in the Page_Load.
Hope that helps someone...

Thanks Robert!
You just saved my day!
I just updated to the new RadControls, and suddenly all my grids are not expanding
I spent 2 hours trying to figure out how to fix it....
Thank you for saving me a lot headache
I would suggest marking your answer as the correct one
