Example

All examples in this topic assume that the grid is bound to the Products table of the Northwind database, unless stated otherwise

The following example demonstrates how to use an unbound column to display a button that, when clicked, will display an editor through which the corresponding data item can be edited.The following code provides the implementation of the Button_Click event. The ProductsEditorWindow derives from Window and allows the data item to be edited. The code for the ProductsEditorWindow is not provided.The following code provides the implementation of the Button_Click event.
