    I have a RadTreeList that uses the TreeListComboEditor as its input for some of the columns. That part works very nicely (aside from the fact that TreeListEditFormItem.ExtractValues returns the selected values from a TreeListComboEditor as a single char instead of the selected value).

    However, I have a situation where a user can change one selected input element and have the list of available options in a different TreeListComboEditor change: the first dropdown asks "Is this currency or quantity" and the second dropdown should show either a list of dollar-values or a list of item-quantities. I turned AutoPostBack to 'true' for the first control, and I can see that it is indeed posting back. However, since the TreeListComboEditor is created dynamically, I can't wire up the object's events ahead of time, and I don't see any available events that I can listen for. Is my only option 'parse the request arguments and search the page controls for the update panel?'
