silverlight 4.0 - WpfToolkit DataGrid does not work in Windows Phone 7

Question

I am trying to use WpfToolkit DataGrid in Windows Phone 7 project (Silverligt 4) and it's not working. Here is the XAML:

<UserControl x:Class="SilverlightControls.Grid"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d"
    xmlns:wtk="clr-namespace:Microsoft.Windows.Controls;assembly=WPFToolkit"
    d:DesignHeight="480" d:DesignWidth="480">

    <Grid x:Name="LayoutRoot" Background="#FF1F1F1F" Width="960">
        <Grid x:Name="TitleGrid">
            <TextBlock Text="{Binding Title}" Style="{StaticResource PhoneTextPageTitle2Style}"/>
        </Grid>
        <wtk:DataGrid>
        </wtk:DataGrid>
    </Grid>
</UserControl>

The project compiles fine but crashes at runtime trying to load this control. The best clue I got so far is from Visual Studio Designer. Once I add wtk:DataGrid to the control the visual designer does not load and below is the exception it displays.

Could it be that WpfToolkit relies on PresentationFramework.dll and it's not available in SL4?

Answer 1

Just when I was about to post the question, the StackOverflow tags auto-suggest showed that there is Silverlight Toolkit. Clearly this is what I should use.

Since I put all that effort into the question I will leave the question and the answer as a testemant to StackOverflow awesomeness in auto-answering my question.

EDIT You need Silverlight 3 Toolkit binaries to use DataGrid. You need to add these four references to the project:

1. System.ComponentModel.DataAnnotations.dll
2. System.Windows.Controls.Data.dll
3. System.Windows.Controls.Data.Input.dll
4. System.Windows.Data.dll
