WPF DataGridComboboxColumn 与 Combobox 相同的样式

Question

我有一个包含数据网格的应用程序。在此数据网格中，有 DataGridComboboxColumn 类型的列。诀窍是我在针对 Combobox 的资源字典中定义了一个样式，但它似乎不适用于编辑模式下的 DataGridComboboxColumn，但它适用于 "regular" Combobox。

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

有什么想法吗？

您可以将 EditingElementStyle 分配给您创建的组合框样式。参考下面的代码。

<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>
