I'm using a nested RadGrid, which should only be populated when a particular row in the parent Rad Grid is expanded.  This is working fine for the first page of the parent grid, and only the parent's NeedDataSource is fired.  Also, the child nested grid's NeedDataSource is correctly only firing upon expanding a row.

However, when I page the parent grid to the second page, the NeedDataSource of the child RadGrid is firing for each row of the parent's RadGrid, even though none of the rows in the parent grid are expanded.

What can I do to fix this? TelerikRadGrid1 in my code below is the parent RadGrid, and TelerikRadGrid2 is the nested child RadGrid.  SOrry if the code below is a bit long.  I'm really stuck at this point.  Thanks for any help!

Hi Tayyab,

Our developers are aware of the issue and they consider implementing a fix to change this behavior or leave it as a limitation. Therefore, probably this fix will be introduced in the future releases but I am afraid I cannot give you a strict deadline.

Thank you for your valuable feedback.

I had this same issue. I was able to get around it by creating a global Boolean called MainGridIsRebinding. I set it to true in the NeedDataSource block for the Main grid. In the NeedDataSource block for the dynamically built nested grid, I check for false on this Boolean before I let it go to the DB and populate the child grid. So far it seems to be working.

Hope this helps anyone out there with the same issue.

And FYI - this wasn't just an issue with paging. The nested grids were trying to load any time I did a rebind() on the main grid.

Kevin, that sounds like a good work-around to the problem.  The project that I was working on has already been deployed (with this particular issue unresolved), but if/when we do another round of development/bug fixes, I will try it out.
