• Silverlight 1.0 Carousel

  I tried creating a stripped down version of a Carousel control (in Silverlight 1.0) which displays images. As of now it just rotates in the clockwise direction on ‘MoueEnter’. I will try to add more features to it as I move on to Silverlight 1.1. You can see it runing here. Here is the Source.     Posted Nov 07 2007, 03:33 AM by Sajiv with 1 comment(s) Filed under: Silverlight

• How to change the Source property of a Frame control in WPF?

  Suppose we have a Frame control in our application and it inherits it’s ‘DataContext’ from its parent Window. If we need to change the ‘Source’ property when a certain condition is true then we could style the Frame as seen below: <Style x:Key="FrameStyle" TargetType ="{x:Type Frame}"> <Setter Property="Source" Value="{Binding XPath=@Path}"/> <Style.Triggers> <DataTrigger Binding="{Binding XPath=@IsRedirectionRequired}" Value="Yes"> <Setter Property="Source" Value="{Binding XPath=@AlternatePath}" /> </DataTrigger> </Style.Triggers> </Style>  We are assuming that our DataSource is an XML file which contains the path to various loose XAML files and an alternate path for each. Something like this. <Files> <File Name="File1" Path="http://www.identitymine.com" AlternatePath="http://www.blendables.com/" IsRedirectionRequired="Yes"/> <File Name="File2" Path="http://www.google.com" AlternatePath="http://www.msn.com" IsRedirectionRequired="No"/> </Files>  Here is a sample.     #Note: Setting the ‘Source’ or ‘Content’ property on the Frame locally (either using DataBinding or hard coded values) as seen below will result in the style having no effect. <Frame Source="{Binding XPath=@Path}" Grid.Column="1" Width="Auto" Height="Auto" Style="{StaticResource FrameStyle}" />   Posted Nov 07 2007, 12:59 AM by Sajiv with no comments Filed under: Styles
