在哪里可以找到WPF DataGrid的XAML模板？

Question

我想修改Microsoft WPF DataGrid(4.0版本)的模板,但我不确定现有模板是什么样的.有谁知道它是什么或我在哪里可以找到它？

Answer 1

我建议进入Blend(如果你有的话)并提取模板.否则,您可以使用XAMLWriter获取XAML.

这个不幸的命名页面(我不认为这真的是"孩子的东西",你呢？)有一个做这两件事的例子.

如果页面确实消失了(2009年在后视镜中相当远):

// Get the template from the control 
ControlTemplate template = ctl.Template;

// We want our xaml of be properly indented, ohterwise
// we would not be able to indent them.
XmlWriterSettings xmlSettings = new XmlWriterSettings();
xmlSettings.Indent = true;

// Make the string builder
StringBuilder sb = new StringBuilder();
XmlWriter writer = XmlWriter.Create(sb, xmlSettings);
XamlWriter.Save(template, writer);


// Now the sb.ToString() should give us the template

所有归功于Shafqat Ahmed.

这是我从Blend 4中得到的:
