Hey There,
I have a RadGrid which currently works with its GroupLoadMode set to SERVER. This way, I can preserve expanded and collapsed groups and set the grid back to the way it was after a postback was made to the server. However, I would like to change the GroupLoadMode to CLIENT in order to speed up the UI. The same code will still remain to put the grid back to its state it was before a postback was requested, but since I'm handling it on the client, I need to get the INDEX of the group that was just expanded (or the Expand/Collapse Button's ID) in order to add/remove that value from the hidden field where I save expanded group's IDs.
So what am I asking here: (a) Get the grouping index of the item being expanded on the client side, or (b) Get the ID of the expand/collapse button of the group on the client side.
