Question

我创建了一个简单的用户控件，即使应用程序运行正常，也可以将模板应用到

我在这里定义控制模板

的App.xaml

    <ControlTemplate x:Key="myWindowTemplate">
        <Grid x:Name="myGrid" Background="Black" Width="50" Height="50">
            <ContentPresenter Name="Content"></ContentPresenter>
        </Grid>
    </ControlTemplate>

</Application.Resources>

我的用户控制

Test.xaml

<Grid x:Name="LayoutRoot">
    <Button Name="myButton" Template="{StaticResource myWindowTemplate}" Foreground="White" Content="CLICK" ></Button>
</Grid>

我正在使用用户控件的页面以及发生AG E UNKOWN_ERROR的页面。如果我从test.xaml删除应用模板并删除Template =“{StaticResource myWindowTemplate}”，则错误消失，所以我知道它在我的模板定义中有什么不好???

Answer 1

我认为您需要<ControlTemplate>上的TargetType =“网格”：

<ControlTemplate x:Key="myWindowTemplate TargetType="Grid">

...

此外，Grid不是ContentControl，因此我不认为您放入模板中的ContentPresenter会按照您期望的方式运行 - 它甚至可能导致错误。

Answer 2

实际上，从您发布的代码中，您的TargetType应该是Button，因为您正在将模板应用于按钮。
