WPF中DataGrid中的DataGridCheckBoxColumn用法（全选，全否，反选）

原文:WPF中DataGrid中的DataGridCheckBoxColumn用法（全选，全否，反选）

  前台代码

           <DataGrid.Columns>
                         <DataGridCheckBoxColumn Header="选择" Binding="{Binding Path=RUID}" x:Name="cRUID"></DataGridCheckBoxColumn>
                         <DataGridTextColumn Header="结算类型" Binding="{Binding Path=CTYP}" x:Name="cCTYP" IsReadOnly="True" >       </DataGridTextColumn>

          </DataGrid.Columns>

 使用模板列全选：

 前台代码：

         <DataGridCheckBoxColumn Binding="{Binding Path=RUID,RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type DataGridRow}}}" x:Name="cRUID">
                             <DataGridCheckBoxColumn.HeaderTemplate>
                                 <DataTemplate>
                                 <CheckBox x:Name="ckbSelectedAll" Content="全选" Checked="ckbSelectedAll_Checked" Unchecked="ckbSelectedAll_Unchecked" IsChecked="False"  />
                                 </DataTemplate>
                             </DataGridCheckBoxColumn.HeaderTemplate>
                         </DataGridCheckBoxColumn>              

 后台 c#代码

         ///

         {
             this.dgList.SelectAll();
         }

         ///
