Introduction to MVC 2 with Visual Studio 2010

Microsoft MVC 2 in Visual Studio 2010


The Microsoft ASP.NET MVC framework is Microsoft’s newest framework for building web applications. The ASP.NET MVC framework was created to support pattern-based software development. In other words, the framework was designed to make it easier to implement software design principles and patterns when building web applications.

An MVC application, a Model View Controller application, is divided into the following three parts:

• Model: An MVC model contains all of an application’s logic. The model includes all of an application’s validation logic, business logic, and data access logic.

• View: An MVC view contains HTML markup and view logic.

• Controller: An MVC controller contains control-flow logic. An MVC controller interacts with MVC models and views to control the flow of application execution. which handle incoming requests, perform operations on the domain model, and choose a view to render back to the user

Adding a VideoBrush in Silverlight

Using a VideoBrush in Silverlight Application


VideoBrush elements are very similar to the ImageBrush. Instead of an image, they define a video MediaElement that is applied as a brush. You can apply them to the properties of Silverlight controls the same way that the ImageBrush is applied.

To apply a VideoBrush to a Silverlight control, you need to define the VideoBrush element just as you do with an ImageBrush. However, different from an ImageBrush, you need to set a SourceName property that points to the x:Name of the MediaElement. Therefore, you also need to define a MediaElement separate from the Silverlight control. If you do not want the video to be displayed outside of the Silverlight control, set the Opacity property of the MediaElement to 0.

Eg:

< MediaElement Source="first.wmv"
x:Name="movie"
Opacity="0"/ >


< TextBox Height="100" Width="150" >
< TextBox.Background >
< VideoBrush SourceName="movie" Stretch="UniformToFill"/ >
< /TextBox.Background >
< /TextBox >
