Hi Deepa,

GridViewComboBoxColumn is used when you have a lookup value scenario. A simple example is imagine if we have a Customer object that has a property Country. We want to databind the ComboBox with all countries and bind selected country to the Country property of the Customer.

In your case you should use CellTemplate property of the column to define a DataTemplate with ComboBox. This combo's ItemsSource will be databound to the collection property of your object. I'm sending you an example which illustrates how to achieve this.

Hope this helps.

Hello Deepa,

If you want to use GridViewComboBoxColumn you should set its ItemsSource to some collection the same you databind the GridView. Check out this forum post for example.
