在WPF DataGridView中,如何获取点击单元格的值?

刚刚接触WPF,这个问题可能比较弱.但是对我这种新手来说确实很头疼...

问题很简单.WPF绑定到一个List.设置如下:





<my:DataGrid AutoGenerateColumns="False" 

                             Name="dataGridView2" 

                             CanUserReorderColumns="False" 

                             CanUserResizeColumns="True"

                             CanUserSortColumns="False" 

                             FrozenColumnCount="3" 

                             GridLinesVisibility="Horizontal"

                             PreviewMouseLeftButtonDown="DataGridCell_PreviewMouseLeftButtonDown"

                             SelectionMode="Extended"

                             SelectionUnit="FullRow"

                             >



                    <my:DataGrid.Columns>

                        <my:DataGridTextColumn Header="名称" Width="150" Binding="{Binding Name}"/>

                        <my:DataGridTextColumn Header="编码" Width="180" Binding="{Binding Code}"/>

                    </my:DataGrid.Columns>



                </my:DataGrid>

在DataGridCell_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)事件中却没法定位单击或当前光标所在的单元格.上网狂搜之后依然没有得到答案.请问高数如何解决这个小小的问题?谢谢 --------------------编程问答-------------------- 算位置怎么可能定位不到

            foreach (DataGridCellInfo cell in this.dataGrid1.SelectedCells)

            {

                try

                {

                    TextBlock cellTB = cell.Column.GetCellContent(cell.Item) as TextBlock;

                    MessageBox.Show(cellTB.Text.ToString());

                }

                catch (Exception)

                {

                    CheckBox chB = cell.Column.GetCellContent(cell.Item) as CheckBox;

                    MessageBox.Show(chB.IsChecked.ToString());

                }

            }

--------------------编程问答-------------------- 可能是因为属性设置中有 SelectionUnit="FullRow”（选中的是整行，而不是某个单元格），也不知道你要做什么处理 --------------------编程问答-------------------- 楼上那位的代码写在SelectedCellsChanged事件里就可以了

补充：.NET技术 ,  C#
