编辑DataGridCell时如何创建类似“命令”的事件

Question

In my program I have a DataGrid with 4 different columns. I would like to make it so that, in one of the columns, when a cell is selected for editing, I am able to change the content of that cell programmatically. For example, on edit, the current string value in the selected cell might change to "selected" . I've looked through the DataGridCell class here , and haven't really found anything that would detect an edit to a cell. It would be nice if there was like some "cellClick" event for each DataGridTextColumn in xaml. How do I achieve this type of handler?

The xaml of my DataGrid :

<DataGrid ItemsSource="{Binding SysModel.SystemCollection}" MinColumnWidth="50" ColumnHeaderStyle="{StaticResource HeaderStyle}" RowStyle="{StaticResource RowStyleWithAlternation}" CellStyle="{StaticResource CenterCellStyle}"
          RowHeaderWidth="0" AlternationCount="2" GridLinesVisibility="Horizontal" SelectionUnit="Cell" CanUserAddRows="False" AutoGenerateColumns="False" Height="471" Name="dataGrid1" Width="468" Canvas.Left="40" Canvas.Top="17">
    <DataGrid.Columns>
        <DataGridTextColumn Header="{DynamicResource cart}" Width="Auto" IsReadOnly="True" Binding="{Binding cartNum}" />
        <DataGridTextColumn Header="{DynamicResource ipAddress}" Width="100" IsReadOnly="False" Binding="{Binding ipAddress}" />
        <DataGridTextColumn Header="{DynamicResource portNumber}" Width="70" IsReadOnly="False" Binding="{Binding PortNumber}" />
        <!-- **This is the column that contains the cells I want to have this event for** -->
        <DataGridTextColumn Header="{DynamicResource configuration}" Width="*" IsReadOnly="False" Binding="{Binding Configuration}" />
        </DataGrid.Columns>
        <DataGrid.Resources>
            <SolidColorBrush Color="#726AA5" x:Key="{x:Static SystemColors.HighlightBrushKey}" />
        </DataGrid.Resources>
</DataGrid>

DataGridCell fires Selected event when it is selected. I presume Before it is being edited by user, it should be selected.
