In this exercise, you ll use Expression Blend to add and animate transformations. 1. Create a new Silverlight application in Expression Blend called Ch13_BlendTransforms. Add two ColumnDefinition elements and two RowDefinition elements so the root Grid is equally divided into four cells, as follows: <Grid x:Name="LayoutRoot" Background="White" > <Grid.RowDefinitions> <RowDefinition/> <RowDefinition/> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition/> <ColumnDefinition/> </Grid.ColumnDefinitions> </Grid> 2. Next, add two rectangles to each of the cells that you just created. Create two sets of rectangles: one set with StrokeThickness="1" and another with StrokeThickness="5". Also, name the second set of rectangles recTrans. Add the following code: <Grid x:Name="LayoutRoot" Background="White" > <Grid.RowDefinitions> <RowDefinition/> <RowDefinition/> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition/> <ColumnDefinition/> </Grid.ColumnDefinitions>

An important aspect of any web application is verifying that the data the user has input is valid. This ensures that your application is secure (e.g., so that no one is able to attempt Structured Query Language [SQL] injection attacks) and the user experience is optimized; only appropriate data is sent to the server and returned from the server. ASP.NET introduces a suite of self-sufficient validation controls that can be used to ensure that the content of your page meets validation rules. These are very useful controls, relieving you from writing reams of validation code to ensure that the correct data has been input.

Tim originally developed the Web as a more convenient way for people to publish their academic papers. More important, the Web provided a way to hyperlink between papers on different machines. People soon created gateways from the Web to the data already published using older technology like FTP Gopher, and Wide Area Information Servers (WAIS). As more , and more of this information came online, it became impossible to keep track of what there was and where it was.
