如何基于默认的DataGrid样式创建样式?

I have custom control that extends DataGrid. It is called ExtendedDataGrid. I want to provide style for ExtendedDataGrid that is the same as DataGrids style except it changes the template. I have tried something like this:

我有扩展DataGrid的自定义控件。它被称为ExtendedDataGrid。我想为ExtendedDataGrid提供与datagrid样式相同的样式，但它更改了模板。我试过以下方法:

<Style TargetType="{x:Type MyControls:ExtendedDataGrid}" BasedOn="{StaticResource {x:Type DataGrid}}">
    <Setter Property="Template">
    ...
    </Setter>
</Style>

But it says that that the resource is not found.

但是它说没有找到资源。

So I try:

所以我尝试:

<Style TargetType="{x:Type MyControls:ExtendedDataGrid}" BasedOn="{StaticResource {ComponentResourceKey ResourceId=DataGridStyle, TypeInTargetAssembly={x:Type DataGrid}}}">
    <Setter Property="Template">
    ...
    </Setter>
</Style>

But it also does not work... So what do I do ?

但它也不起作用……我该怎么做?

Well mystery is solved :)

好吧，谜底解开了:)

My first code above actually works:

我上面的第一个代码实际上是有效的:

<Style TargetType="{x:Type MyControls:ExtendedDataGrid}" BasedOn="{StaticResource {x:Type DataGrid}}">
    <Setter Property="Template">
    ...
    </Setter>
</Style>

I thought that it is not working becase VS (or Resharper) showed error in my code saying that resource is not found... Bug in VS (or Resharper) :(

我认为它不能工作，因为VS(或Resharper)在我的代码中显示错误，说找不到资源……错误在VS(或Resharper):(

If you create a style with a TargetType property and base it on another style that also defines a TargetType property, the target type of the derived style must be the same as or be derived from the type of the base style.

如果您使用TargetType属性创建一个样式，并将其基于另一个样式(也定义了TargetType属性)，则派生样式的目标类型必须与基本样式的类型相同或派生。

Your grid does inherit from DataGrid, right?

你的网格确实继承自DataGrid，对吧?
