WPF DataGridComboboxColumn風格與Combobox相同

Question

我有一個包含數據網格的應用程序。在這個數據網格中，有DataGridComboboxColumn類型的列。訣竅是我在資源字典中定義了一個定位Combobox的樣式，但它似乎不適用於編輯模式下的DataGridComboboxColumn，但它在「常規」Combobox上執行。

我無法重複資源，因爲DataGridComboboxColumn不可用作爲目標類型。

有什麼想法？

您可以將EditingElementStyle分配給您創建的組合框樣式。請參考以下代碼。

<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>
