        Me.Title = ApplicationStrings.HomePageTitle

        '<!-- load the datagrid -->
        Module1._Context.Load(Module1._Context.GetGESECsQuery())

XAML

 <dxg:GridColumn Header="TRAIL" FieldName="secUserName" >
 <dxg:GridColumn.DisplayTemplate>
 <ControlTemplate>
 <StackPanel>
 <dxe:TextEdit  EditValue="{Binding  Path=secUserName}"></dxe:TextEdit>

 </dxg:GridColumn>

问题

单击编辑文本时（通过将行置于编辑模式{侧面有铅笔图}），将显示 SECUSERNAME 的内容

但在只显示记录的正常情况下，textedit 不显示任何内容。

是的，调试器显示 secusername 无效，但为什么呢？我应该怎么做才能做到这一点？

请尝试更改您的绑定代码如下：

"{Binding Path= DisplayText, Mode=OneWay, RelativeSource={RelativeSource TemplatedParent}}"

对你起作用吗？
