DataGrid添加ComboBox模板列

首先在添加一个模板列

              <DataGrid.Columns>
                    <DataGridTemplateColumn  Header="ComboBox模板列" >
                        <DataGridTemplateColumn.CellTemplate>
                            <DataTemplate>
                                <ComboBox ItemsSource="{Binding Source={StaticResource ResourceKey=SelectedTypeResource}}" DisplayMemberPath="Element[ItemName].Value" Text="{Binding Element[SelectedType].Value, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"></ComboBox>
                            </DataTemplate>
                        </DataGridTemplateColumn.CellTemplate>
                    </DataGridTemplateColumn>
                </DataGrid.Columns>

申明一个ComboBox下拉菜单绑定内容的数组

public static XElement[] SelectedTypeResource = new XElement[] {
new XElement("Item",new XElement("ItemName","下拉菜单一"),new XElement("ItemCode",1)),
new XElement("Item",new XElement("ItemName","下拉菜单二"),new XElement("ItemCode",2))
};

在构造函数中加入本地资源字典里

public MainWindow()
{
InitializeComponent();
(this.Resources["SelectedTypeResource "] as ObjectDataProvider).ObjectInstance = SelectedTypeResource ;

}

在设计器里面

<Window.Resources>
<ObjectDataProvider x:Key="SelectedTypeResource "></ObjectDataProvider>
</Window.Resources>
