I have a grid which has a templated column (which is a DropDown control). On page load, rows are added to the grid and the drop down controls are populated. I then use and AJAX update panel to perform something when a button is pressed. This all works fine until i move the controls into one of the panes of the splitter control. When i try to reference the drop down control the index is out of range and the cell items has a length of 0 even though the row count is correct.

 Any ideas becuase is all works fine outside of the splitter
