<data:DataGrid IsReadOnly="False" x:Name="dGridExpressions" AutoGenerateColumns="False">
     <data:DataGrid.Columns>
             <data:DataGridTextColumnBinding="{Binding Steps}" Header="Steps"/>
                <data:DataGridTemplateColumn x:Name="ContentColm" Header="Expression" IsReadOnly="True">
                                		<data:DataGridTemplateColumn.CellEditingTemplate>
   <DataTemplate>
      <RichTextBox x:Name="ContentText" MinWidth="610" 		BorderThickness="1" KeyDown="TextBox_KeyDown" Margin="1">
      <Paragraph>
            <Run Text="{Binding Path=RuleCondition, Mode=TwoWay}" />
       </Paragraph>
       </RichTextBox>

                            </data:DataGrid>

推荐答案

为什么不使用绑定从richtextbox中获取适当的值，而不是使用keydown事件. 这将是正确的进行方式.

Why don''t you just use binding to get the appropriate values from the richtextbox instead of using the keydown event.
This would be the correct way to proceed.
