文本框仅在行处于编辑模式时显示内容

问题描述：

我已经做了我能想到的所有事情，但是文本框只是不显示值.

I have done every thing I can think of, but the textbox just does not display the values.

我的错误在哪里?

 <dxg:GridColumn FieldName="secUserName" Header="TRAIL">

                                        <dxg:GridColumn.DisplayTemplate>
                                            <ControlTemplate>
                                                <StackPanel>
                                                    <TextBox Text="{Binding Path=Data.secUserName, Mode=TwoWay}" ></TextBox>

                                                </StackPanel>
                                            </ControlTemplate>
                                        </dxg:GridColumn.DisplayTemplate>

和vb

'<!-- load the datagrid -->
        Module1._Context.Load(Module1._Context.GetGESECsQuery())
        GridControl1.AutoPopulateColumns = False
        GridControl1.DataSource = Module1._Context.GESECs

答

我建议您使用我们的TextEdit代替标准TextBox:

I suggest that you use our TextEdit instead of the standard TextBox:

<dxg:GridColumn.DisplayTemplate>
                                            <ControlTemplate>
                                                <StackPanel>
                                                    <TextEdit EditValue="{Binding Path=DataContext.secUserName}"></TextEdit>
                                                </StackPanel>
                                            </ControlTemplate>
                                        </dxg:GridColumn.DisplayTemplate>

如果这样做没有帮助，请删除模板，并确保网格具有绑定到secUserName字段的列，并在运行时显示数据.

If this does not help, please remove the template and make certain that the grid has a column bound to the secUserName field and it shows data in runtime.
