With this post I’ll show you how to create a simple catalog like functionality for your application using RadTileView and RadDataPager. 

We will create a catalog with 10 000 RadTileViewItems distributed in 100 pages and each page will have UI Virtualization. At the end this sample application will look like this:


Demo

We’ll start with a tileview, a datapager

<Grid x:Name="LayoutRoot" Background="White">
    <Grid.RowDefinitions>
        <RowDefinition />
        <RowDefinition Height="Auto" />
    </Grid.RowDefinitions>
 
    <telerik:RadTileView x:Name="myTileView" />
    <telerik:RadDataPager Grid.Row="1" />
</Grid>

… and a simple business item model:

public class BusinessItemViewModel
{
    public string Header { get; set; }
}

Now let’s add a view model for our main page:

public class MainPageViewModel
{
    private ObservableCollection<BusinessItemViewModel> items;
 
    public MainPageViewModel()
    {
        this.items = new ObservableCollection<BusinessItemViewModel>();
        this.LoadSomeItems();
    }
 
    public ObservableCollection<BusinessItemViewModel> Items
    {
        get
        {
            return this.items;
        }
    }
 
    private void LoadSomeItems()
    {  
        for (int i = 0; i < 10000; i++)
        {
            this.items.Add(new BusinessItemViewModel() { Header = i.ToString() });
        }
    }
}

All we have to do now is to associate the view model and the main page, set some styles and bind the RadDataPager and the RadTileView:

<UserControl.DataContext>
    <local:MainPageViewModel />
</UserControl.DataContext>
 
<UserControl.Resources>
    <Style TargetType="telerik:RadTileView">
        <Setter Property="ColumnWidth" Value="325" />
        <Setter Property="RowHeight" Value="275" />
        <Setter Property="MinimizedColumnWidth" Value="180" />
        <Setter Property="MinimizedRowHeight" Value="155" />
        <Setter Property="ColumnsCount" Value="10" />
        <Setter Property="IsVirtualizing" Value="True" />
        <Setter Property="PreservePositionWhenMaximized" Value="True" />
    </Style>
    <Style TargetType="telerik:RadTileViewItem">
        <Setter Property="Background" Value="#06749b" />
    </Style>
    <DataTemplate x:Key="headerTemplate">
        <TextBlock Text="{Binding Header}" />
    </DataTemplate>
    <DataTemplate x:Key="contentTemplate">
        <TextBlock HorizontalAlignment="Center"
                   VerticalAlignment="Center"
                   FontSize="48"
                   FontStyle="Italic"
                   Foreground="#FFFFFF"
                   Text="{Binding Header}" />
    </DataTemplate>
</UserControl.Resources>
 
<Grid x:Name="LayoutRoot" Background="White">
    <Grid.RowDefinitions>
        <RowDefinition />
        <RowDefinition Height="Auto" />
    </Grid.RowDefinitions>
 
    <telerik:RadTileView x:Name="myTileView"
                         ContentTemplate="{StaticResource contentTemplate}"
                         ItemsSource="{Binding PagedSource, ElementName=myDataPager}"
                         ItemTemplate="{StaticResource headerTemplate}" />
    <telerik:RadDataPager x:Name="myDataPager"
                          Grid.Row="1"
                          PageSize="100"
                          Source="{Binding Items}" />
</Grid>

Note that you have to bind the RadTileView to the RadDataPagers PagedSource property.

That is it, now if you run your application you should get a result similar to the one showed above.
