c# - WPF 数据网格组合框列 : how to manage event of selection changed?

Question

我有一个带有组合框列的数据网格

<DataGridComboBoxColumn x:Name="DataGridComboBoxColumnBracketType" Width="70" Header="Tipo di staffa" SelectedValueBinding="{Binding type, UpdateSourceTrigger=PropertyChanged}">                    
            </DataGridComboBoxColumn>

我想要一个仅当用户将值更改为组合框时才触发的事件。我该如何解决这个问题？

我在 CodePlex 上找到了解决方案.这是，有一些修改:

<DataGridComboBoxColumn x:Name="Whatever">                    
     <DataGridComboBoxColumn.EditingElementStyle>
          <Style TargetType="{x:Type ComboBox}">
               <EventSetter Event="SelectionChanged" Handler="SomeSelectionChanged" />
          </Style>
     </DataGridComboBoxColumn.EditingElementStyle>           
</DataGridComboBoxColumn>

在代码隐藏中:

private void SomeSelectionChanged(object sender, SelectionChangedEventArgs e)
{
     var comboBox = sender as ComboBox;
     var selectedItem = this.GridName.CurrentItem;

}
