# Step 2 of 3 Customizing the C1Tile View Control

## Content

In the previous step, we created a WPF or Silverlight application and added the [C1TileView](/componentone/api/wpf/online-tilesview/dotnet-framework-api/C1.WPF.TileView.4.6.2/C1.WPF.TileView.C1TileView.html) control (**C1TileView** in Silverlight) to the project. To customize your application, complete the following steps:

1. Add AllowDrop="True" within the **C1TileView** element on the page to allow users to perform drag-and-drop operations with items in the control. The XAML markup appears similar to the following:

    ```xml
    <c1:C1TileView x:Name="C1TileView1" AllowDrop="True"></c1:C1TileView>
    ```
2. Add three [C1TileViewItem](/componentone/api/wpf/online-tilesview/dotnet-framework-api/C1.WPF.TileView.4.6.2/C1.WPF.TileView.C1TileViewItem.html) objects (**C1TileViewItem** in Silverlight) within the **C1TileView** element so the XAML markup appears similar to the following:

    ```xml
    <c1:C1TileView Name="C1TileView1" AllowDrop="True">
        <c1:C1TileViewItem></c1:C1TileViewItem>
        <c1:C1TileViewItem></c1:C1TileViewItem>
        <c1:C1TileViewItem></c1:C1TileViewItem>
    </c1:C1TileView>
    ```
3. Add **Background** and **Header** properties to each of the **C1TreeViewItem** objects, so the markup appears like the following:

    ```xml
    <c1:C1TileView Name="C1TileView1" AllowDrop="True">
        <c1:C1TileViewItem Background="Red" Header="Red"></c1:C1TileViewItem>
        <c1:C1TileViewItem Background="Blue" Header="Blue"></c1:C1TileViewItem>
        <c1:C1TileViewItem Background="Yellow" Header="Yellow"></c1:C1TileViewItem>
    </c1:C1TileView>
    ```

    Each item now appears in a different color and has text in the header.

In this step you added content to the C1TileView control. In the next step, we view some of the run-time interactions possible in the control.
