Simple Binding - Course Silverlight 3 - Lesson 10 | .net courses

Duration:  19 minutes

Summary: In this video, we start discussing bindings. We will give a simple example on how to bind the font size of a text block to a slider. Then, we will talk more about bindings in the upcoming videos. This example shows us how to connect two elements together with a binding expression (element-to-element binding). We chose to use Blend to do this example, but of course all those changes can be done in Visual Studio as well. We start by adding a slider to the main screen. We placed a text block under the slider. Now instead of giving the FontSize of the text block a static value, we gave it a binding expression. In that expression we set two key values: the ElementName and the Path. In the ElementName we selected the name of the slider, and in the Path we put the property of the slider we are binding to. Now, when the value of the slider change, the font size of the text block will reflect that change as well.

Methodology of the development of example: Good coding standard and simplified design to illustrate the key points.
