如何在silverlight中删除DataGrid周围的边框

当我尝试BorderThickness=“0”BorderBrush=“Transparent”时，如何在silverlight中删除数据网格周围的边框？它删除了网格左右和底部的边框，但没有删除顶部的边框。我认为这是标题边框或其他内容，但不确定我是否也删除了标题标题标题可见性=“无” 如果有人能帮忙就好了

欢呼声

在Silverlight 2 Beta 2中，生成的数据网格被边界包围。不幸的是，仅仅在DataGrid上设置一个属性是无法删除此边界的。要删除此项，需要覆盖DataGrid样式或“皮肤”的定义

每个Silverlight控件（FrameworkElement）的外观都在ControlTemplate中定义。使用样式，可以使用一组自定义XAML代码在应用程序中重写此模板。默认XAML定义可在Silverlight控件样式和模板文档中找到。具体到本主题，DataGrid的XAML定义可以在DataGrid样式和模板文档中找到

在DataGrid XAML中，查找模板定义。找到后，请注意DataGrid的RootElement由三个不同的边界元素包围

这些元素可能是需要删除的项目。要开始定制，需要将DataGrid的样式XAML作为新资源添加到我们的应用程序中。我将直接将其添加到我的UserControl中，但也可以将其添加到应用程序资源中（在App.xaml中）

要将XAML添加到UserControl，请创建一个名为UserControl.Resources的新节点，并将DataGrid XAML复制到其中（使用文档网页上方便的“复制代码”链接）

DataGrid和资源的命名空间定义必须匹配。在复制的XAML中，名称空间是本地的：DataGrid。VisualStudio工具生成的默认名称空间是my:DataGrid。在上面的示例中，我将local的所有引用都更改为my

下一个需要注意的事项是样式必须有一个键。这用于将框架元素（我们的DataGrid）映射到特定的样式定义。我已经给了样式一个TestGrid键，该键在下面的DataGrid定义中使用

此时，当您运行应用程序时，DataGrid应该与以前完全相同（我们还没有更改任何内容）

在开始删除边界元素的定义之前，我希望确保这些是罪魁祸首。要做到这一点，我要把它们的颜色改得更明显一点

运行应用程序时，我会看到一个屏幕

放大来看，很明显这些元素是如何参与DataGrid的显示的

从XAML中删除边框元素将生成所需的结果

希望这不仅为如何从DataGrid中删除边框提供了参考，而且还为定制Silverlight控件提供了快速介绍

您看到的元素是一个名为

ColumnHeaders和WSSeparator的
