The findControl method is not able to find controls when called inside of the event handler for the OnGridCreated event as follows. This will cause an error because findControl() returns null. Shouldn't the controls be loaded at this point? Note that I am able to find controls in the row selected/deselected event handlers.

• load on demand and it just doesn't get to ItemsRequested. 
• I also tried to share a combo between all cells in the second grid, but it's too problematic because you never know where to open the popup. And if you manage to calculate based on offsets it just opens in the wrong direction. 
• I also tried having the third grid load separately once and once each radcombobox opens I copy the innerhtml of the element in the dropdown. That worked, but I have no way of accessing the controls in the third grid because the dom doesn't get updated when I copy the innerhtml. 
• Also tried binding the third grid via ajax request, but how would I know which radcombobox sent the request since I only have a string parameter to differenciate between them?
