Silverlight ItemsControl

Question

Hello,

I am trying to use an ItemsControl to display a DataTemplate. I have this simple example:

<navigation:Page.Resources>
 <DataTemplate x:Key="PictureResultsTemplate">
  <!--<Grid/> -->
  <TextBlock Text="Nick Was Here"></TextBlock>
 </DataTemplate>
</navigation:Page.Resources>    


<Grid x:Name="LayoutRoot">
    <Grid Margin="0,0,8,8">
     <Grid.RowDefinitions>
      <RowDefinition Height="0.102*"/>
      <RowDefinition Height="0.898*"/>
     </Grid.RowDefinitions>
     <Grid.ColumnDefinitions>
      <ColumnDefinition Width="Auto"/>
      <ColumnDefinition Width="*"/>
     </Grid.ColumnDefinitions>

 <ItemsControl x:Name="PictureResults" Margin="0,8,0,0" Grid.Row="2" ItemTemplate="{StaticResource PictureResultsTemplate}">
 </ItemsControl>  

    </Grid>     

</Grid>

How come the textblock text is not visible? Thanks!

I think you are going to need to set the ItemsSource or Items on the items control, or you will have not items to apply your ItemTemplate to.

No, you don't have to bind to a data source. You could add items directly in xaml. See below:

<UserControl
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        x:Class="QuickTests.MainPage"
        xmlns:System="clr-namespace:System;assembly=mscorlib"
        Width="640" Height="480">
    <UserControl.Resources>
        <DataTemplate x:Key="myStringTemplate">
         <StackPanel>
          <TextBlock Text="{Binding}"/>
          <TextBlock Text="Yep, this is an item"/>
         </StackPanel>
        </DataTemplate>
    </UserControl.Resources>
                  <ItemsControl ItemTemplate="{StaticResource myStringTemplate}">
                        <ItemsControl.Items>
                            <System:String>hello</System:String>
                            <System:String>world</System:String>
                        </ItemsControl.Items>
                    </ItemsControl>
    </UserControl>
