What types of data can I bind to WPF?

WPF data binding supports data in the form of .NET objects, XML, and even XAML element objects. To provide some examples, your binding source may be a UIElement, any list object, an ADO.NET or Web Services object, or an XmlNode that contains your XML data. For more information, see Binding sources overview.

What is userdatabinding in WPF?

DataBinding is a mechanism in WPF applications that provides a simple and easy way for applications to display and interact with the data. It allows the flow of data between UI and business model.

How do I bind a listbox to an XML file?

It’s important to remember that when you’re establishing a binding, you’re binding a binding target to a binding source. For example, if you’re displaying some underlying XML data in a ListBox using data binding, you’re binding your ListBox to the XML data. To establish a binding, you use the Binding object.

How do you resolve data binding in XAML?

When data binding is declared on XAML elements, they resolve data binding by looking at their immediate DataContext property. The data context is typically the binding source object for the binding source value path evaluation. You can override this behavior in the binding and set a specific binding source object value.

What happens if the DataContext property is not set on binding?

If the DataContext property for the object hosting the binding isn’t set, the parent element’s DataContext property is checked, and so on, up until the root of the XAML object tree. In short, the data context used to resolve binding is inherited from the parent unless explicitly set on the object.
