Hi,

I need to have a cell updated when a new dropdown value has been selected. Is there some setting for it?

I thought to handle the CellListSelect event and perform ExitEditMode action. That does what I want, but after the CellListSelect event handler the NullReferenceException is thrown inside the infragistics dll, that's probably a bug. Isn't that? However, I didn't try to reproduce that in the small sample application.

Thanks,

Vitaly

Hi Vitaly,
I don't understand your question. Why would you have to do anything to get a cell to update when the user picks a value from a DropDown? This happens automatically.
Do you mean you are creating your own dropdown? If so, then I need more information about what you are doing and what kind of dropdown you are using.

Hi Mike, Thanks for the response. I set the Cell.Style to ColumnStyle.DropDown and populate the cell's ValueList collection. The behavior I'm seeing is that the value that has been selected from the dropdown will be committed only when the cell exits edit mode. I need it to be committed right after the value has been selected. I tried to achieve this by performing ExitEditMode action in the CellListChange event handler but the NullReferenceException is being thrown inside the infragistics dll after the handler finishes execution.
