I have an Ultrawebgrid with a valuelist column (statically loaded with values at Page_Load). When the user selects a value (captured at AfterCellUpdated event), another ValueList is loaded (based on the first valuelist's selected value) and populated for the user to also select. 

My problem is that when the grid is loaded, while the second column values are displayed, when clicking on the cells themselves, no valuelist dropdown is shown, because this is not created until the first column dropdownlist is updated.

What I would like to do is to have both value lists loaded and available at page_load, so as to enable editing of the second valuelist without having to change the first column's value first.

Any ideas on how this can be achieved? Which event should I hook this up to?
