如何在WPF中动态设置ItemTemplate？

Using WPF, I have a TreeView control that I want to set its ItemTemplate dynamically through procedural code. How do I do this? I assume I need to find the resource somewhere.

使用WPF，我有一个TreeView控件，我想通过过程代码动态设置它的ItemTemplate。我该怎么做呢？我假设我需要在某个地方找到资源。

myTreeViewControl.ItemTemplate =   ??

2 个解决方案

#1

If the template is defined in your <Window.Resources> section directly:

如果模板直接在部分中定义：

myTreeViewControl.ItemTemplate = this.Resources["SomeTemplate"] as DataTemplate;

If it's somewhere deep within your window, like in a <Grid.Resources> section or something, I think this'll work:

如果它位于窗口深处，就像在部分或其他地方一样，我认为这将起作用：

myTreeViewControl.ItemTemplate = this.FindResource("SomeTemplate") as DataTemplate;

And if it's elsewhere in your application, I think App.FindResource("SomeTemplate") will work.

如果它在你的应用程序的其他地方，我认为App.FindResource（“SomeTemplate”）将工作。

if your treeview control requires different templates for your items, you should implement DataTemplateSelector class and set it's instance to your tree view. as far as i remember there is a property of DataTemplateSelector.

如果您的treeview控件需要不同的项目模板，则应实现DataTemplateSelector类并将其实例设置为树视图。据我所知，DataTemplateSelector有一个属性。
