WPF DataGridComboboxColumn风格与Combobox相同

Question

我有一个包含数据网格的应用程序。在这个数据网格中，有DataGridComboboxColumn类型的列。诀窍是我在资源字典中定义了一个定位Combobox的样式，但它似乎不适用于编辑模式下的DataGridComboboxColumn，但它在“常规”Combobox上执行。

我无法重复资源，因为DataGridComboboxColumn不可用作为目标类型。

有什么想法？

您可以将EditingElementStyle分配给您创建的组合框样式。请参考以下代码。

<DataGrid AutoGenerateColumns="False" Height="200" HorizontalAlignment="Stretch" ItemsSource="{Binding AcquisitionList}" 
          Margin="0,200,0,0" Name="dataGridAcquisitions" VerticalAlignment="Top" > 
      <DataGrid.Columns> 
       <DataGridComboBoxColumn Header="Mode" Width="SizeToHeader" 
             SelectedItemBinding="{Binding AcquisitionMode}" 
             EditingElementStyle="{StaticResource StandardComboBox}" 
             ItemsSource="{Binding Source={StaticResource AcquisitionModeValues}}"/> 
      </DataGrid.Columns> 
     </DataGrid>
