WPF – Binding Data in an XML file to a ComboBox

Some things in WPF are very different from Windows Forms programming. Lately, I’ve been working on my first real UI in which I’ve used WPF over Windows Forms. Using XAML takes a little bit of getting used to, but I’m finding that I have a lot more control over the UI, along with the obvious advantage of seperating the UI presentation from the actual application logic.

Just the other day I needed to create a ComboBox control on a section of my UI, the items in which would need to be loaded from an XML file at runtime. The XML file was to be included as a resource.

The XML file looked something like this:






...

I wanted the ‘name’ attribute from each Language node to be bound to my ComboBox. In order to do this, first we need to define the XML file as a resource in our XAML:





...
...

Then, we just need to add the ItemsSource, SelectedValuePath, and DisplayMemberPath to the ComboBox XAML, specifying the resource we declared earlier, and the attribute that we want to bind:




Note the ‘SelectedItem’ can be set as well from the XAML, It’s set to ‘Arabic’ in the above example.
