URGENT - Add blank to GridViewComboBoxColumn?

[Lindsay Miles]

Hello,

PLEASE SOMEONE ANSWER THIS ASAP.

I bind a GridViewComboBoxColumn to a list of objects, now problem at all with anything there including setting to currently selected value.
I need to give the user the option of selecting blank item as that field can be empty. Need to put a blank item into the GridViewComboBoxColumn at the top of the list.

HOW CAN I DO THAT? Standard combobox is easy and I don't want to use those in a CellEditTemplate either as using that will change the ViewModel(s) and bindings quite a bit.

Thanks

Hello,

 You can inherit from GridViewComboBox column and override the CreateCellElement and CreateCellEditElement. There you can access the RadComboBox content, without specifying new DataTemplates.
