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>
