This leads us to another relative source mode which is the Find Ancestor one. Mode Find Ancestor In this case, a property of a given element will be tied to one of its parents, Of Corse.The main difference with the above case is the fact that, it's up to you to determine the ancestor type and the ancestor rank in the hierarchy to tie the property.

This topic focuses on data templating features and is not an introduction of data binding concepts.For an introduction of the WPF styling and templating model, such as how to use a Style to set properties on controls, see the Styling and Templating topic.In addition, it is important to understand , which are essentially what enable objects such as Style and Data Template to be reusable.The Relative Source is a markup extension that is used in particular binding cases when we try to bind a property of a given object to another property of the object itself, when we try to bind a property of a object to another one of its relative parents, when binding a dependency property value to a piece of XAML in case of custom control development and finally in case of using a differential of a series of a bound data. Mode Self: Imagine this case, a rectangle that we want that its height is always equal to its width, a square let's say.All of those situations are expressed as relative source modes. We can do this using the element name For that case we are not obliged to mention the name of the binding object and the Width will be always equal to the Height whenever the height is changed.For instance, consider this example and compare it to the first one: Notice how this example uses a simple string tooltip for the first button and then a much more advanced one for the second button.

In the advanced case, we use a panel as the root control and then we're free to add controls to that as we please.

Tooltips, infotips or hints - various names, but the concept remains the same: The ability to get extra information about a specific control or link by hovering the mouse over it.

WPF obviously supports this concept as well, and by using the Tool Tip property found on the Framework Element class, which almost any WPF control inherits from.

Here's an example: The first place you will want to look is the Visual Studio Output window.

It should be at the bottom of your Visual Studio window, or you can activate it by using the [Ctrl Alt O] shortcut.

Specifying a tooltip for a control is very easy, as you will see in this first and very basic example: As you can see on the screenshots, this results in a floating box with the specified string, once the mouse hovers over the button.
