Every sample that I have seen uses static XML in the xmldataprovider source, which is then used to databind UI controls using XPath binding. Idea is to edit a dynamic XML (structure known to the developer during coding), using the WPF UI. Has anyone found a way to load a dynamic xml string (for example load it from a file during runtim...
I have a TreeView bound to an XmlDataProvider. The name of a node is reflected in the tree and the data of the node is in a TextBox. When you click on a tree item, it loads the data in the TextBox.

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. How can I modify the following code so that t...

When I set the Source property using an absolute URI, everything works as expected: provider.Source = new Uri(@"C:\bi...
Suppose I have a UserControl whose DataContext is set to an object that has an XmlDataProvider property. I would like to bind to this property in my control's XAML, and specify some XPath. I tried this: <TreeView ItemsSource="{Binding Path=PropertyName, XPath=/items/item/*}"> At runtime I get the exception "BindingExpression with XPat...
Hello guys. Back again this time working with data providers. Well i been doing a bit of training with Flex, and I've searched, and i managed to get a ComboBox being populated through XML data.

I am struggling to work out how to use default namespaces with XmlDataProvider and XPath bindings. There's an ugly answer using local-name <Binding XPath="*[local-name()='Name']" /> but that is not acceptable to the client who wants this XAML to be highly maintainable. The fallback is to force them to use non-default namespaces in the ...

Second time there is no lag. I'm thinking this is due to fact that contents are lazy loaded from disk. How do I reduce this lag? ...
