WPF 数据网格组合框列:如何管理选择更改的事件? [英] WPF datagrid combobox column: how to manage event of selection changed?

问题描述

我有一个带有组合框列的数据网格

I have a datagrid, with a combobox column

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

我想要一个仅在用户将值更改到组合框时触发的事件.我该如何解决?

I want an event that is fired only when the user changes the value into the combobox. How can I resolve this?

推荐答案

我在 CodePlex 上找到了解决方案.这是，经过一些修改:

I found a solution to this on CodePlex. Here it is, with some modifications:

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

并在代码隐藏中:

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

}
