我想知道如何在Master-Detail网格控件中更改列标题的名称。我已设法使用以下代码更改了Master标题的名称：
<dxg:GridColumn FieldName="SaleID" DisplayMemberBinding="{Binding SaleID}" Visible="False"/>
然而，当我尝试将相同的内容应用于我的详细信息时：
<dxg:GridColumn FieldName="Item Name" DisplayMemberBinding="{Binding SaleItemMainName}" HorizontalHeaderContentAlignment="Center"/>
它添加了另一列而不是重命名标题，因此我得到两个具有SaleItemMainName值的列，它们的标题被称为：
供参考，这是我的网格控制的XAML代码：
<dxg:GridControl Grid.Row="1" x:Name="salePendingGC" AutoGenerateColumns="AddNew" Margin="20" Grid.ColumnSpan="2" Visibility="Hidden" >
<dxg:GridControl.View>

答案 0 :(得分：0)
列的FieldName属性必须是要显示的属性的路径：ItemName或SaleTotal或SaleItemMainName等。
您可以使用Header属性定义标题，如下所示：
<dxg:GridControl AutoGenerateColumns="None" EnableSmartColumnsGeneration="False" ItemsSource="{Binding Persons}">
<dxg:GridControl.View>
<dxg:TableView AllowPerPixelScrolling="True" ShowTotalSummary="True" EditorShowMode="MouseUp"/>
</dxg:GridControl.View>
<dxg:GridControl.Columns>
<dxg:GridColumn FieldName="ForeName" Header="Vorname" />
<dxg:GridColumn FieldName="LastName" Header="Nachname" />
</dxg:GridControl.Columns>
</dxg:GridControl>
通常，如果我手动定义我的列，我会将AutoGenerateColumns设置为None，否则可能会添加一些意外的列。
只有在特殊情况下才需要DisplayMemberBinding，如果您的单元格应以特殊方式显示。
