wpf RelativeSource binding

wpf RelativeSource binding RelativeSource has four types Self FindAncestor TemplatedParent PreviousData a.Self Self is used in scenarios where the binding source and binding target are the same. One property of an object is bound to another property of the same object. For example, let’s take an ellipse with the same height and width. Add the code given below in the XAML file. The width property is bound relative to the height property. b.FindAncestor FindAncestorAs the name suggests, this option is used when the binding source is one of the ancestors (parents) of the binding target. Ancestors can be found at any level using the FindAncestor extension. Now, let’s use the FindAncestor extension to bind the ancestor’s Name property to the Content property of the child element button. c.TemplatedParent TemplatedParent is a property that enables you to create a control template that contains a small number of unknown values. These values ​​depend on the properties of the control to which the ControlTemplate is applied. d.PreviousData PreviousData is rarely used and represents the change in value relative to previous data.
