Hi

 

Here is a problem that one of my colleagues who is just starting to use WPF got himself into. He was working on an application that displays items using an ItemsControl and uses a DataTemplate. Inside the DataTemplate he used an Image. Here is the Xaml code:

 

   1: <Window.Resources>
   2:         <Image Source="Creek.jpg" x:Key="IMG"></Image>
   3:     </Window.Resources>
   4:     <Grid>
   5:         <ItemsControl ItemsSource="{Binding}">
   6:             <ItemsControl.ItemTemplate>
   7:                 <DataTemplate>
   8:                     <Border BorderThickness="2" BorderBrush="Black" 
   9:                             CornerRadius="3" MinHeight="10">
  10:                         <ContentControl Content="{StaticResource IMG}"/>
  11:                     </Border>
  12:                 </DataTemplate>
  13:             </ItemsControl.ItemTemplate>
  14:         </ItemsControl>
  15:     </Grid>

This is a much simpler example, but the principal is the same.

 

Can you see what was he doing wrong?

SVG (Scalable Vector Graphics) is an open W3C standard for graphics file format and Web development language based on XML. Those image are made up of lines, curves and other “smooth” elements so when you zoom in on a SVG it stays smooth (unlike GIF, JPEG, PNG). 

Imagine you can draw some of your user interface elements in a vector drawing application like: Adobe,   InkScape (free) or Skencil (free) and convert your work into WPF XAML or Silverlight XAML. ViewerSVG  (SVG to xaml converter) is your tool.
