Question

这是我的自定义控件，它扩展了Telerik RadTileViewItem控件：

 <telerik:RadTileViewItem x:Class="CrmActivityTimer.Customcontrols.TimerTile"

</Grid>

我正在尝试在标头中为此控件添加一个按钮，以从TileView中删除该控件的实例。但是，关于此问题的每个教程都涉及带有自定义标头的默认RadTileViewItem。我想在RadTileViewItem的扩展上修改标头。我已尝试在http://www.telerik.com/forums/customize-radtileview，http://www.telerik.com/forums/header-template和其他方面使用示例代码，但我最终得到了我的TimerTile控件，所有控件都已就位但没有自定义标头或带有自定义标头的TimerTile控件到位，但没有其他控制。

有谁知道我怎么做到这一点？我已经尝试将所有控件移动到模板本身，但我无法弄清楚如何做到这一点，我很确定它应该可以没有太多问题。

在WPF中更改控件外观的常用方法是为它提供一个新的ControlTemplate，它定义构成所需外观的控件。但是，为了做到这一点，您需要找到Telerik的默认RadTileViewItem ControlTemplate XAML，然后用它启动自定义ControlTemplate。

如果您知道如何编写XAML，那么找不到默认ControlTemplate的每个部分以及添加Button的位置都不难。请阅读MSDN上的Control Authoring Overview页面以获取更多信息。

如何在扩展Telerik RadTileViewItem的自定义控件的标题中添加按钮？
