阅读更多关于 How to Bind an XmlDataProvider Class Property to a XAML TreeView

问题 I would like to bind a TreeView control I have defined in XAML to a property in its code-behind class. I already read through a WPF Basic Data Binding FAQ, but the example in the comments at the very bottom of the page didn't work when I tried to use an XmlDataProvider as the binding source.

The problem is, since the underlying data is xml, every value(attributes of the node) is a string, but some of the values represent numerical values.

How to bind XmlDataProvider.Source to MVVM property

阅读更多关于 How to bind XmlDataProvider.Source to MVVM property

So short of cobbling the binding together procedurally is there a way to declaratively bind the XmlDataProvider Source ? If I try to forgo the data provider and bind the tree directly to an XmlNode
