Question

I want to enable text wrapping in the WPF DataGrid column headers and the content of the rows.
Searching for solutions, I often stumble over something like this. The problem is, that it is not working for me.

First of all I have problems with this line:

xmlns:primitives="clr-namespace:Microsoft.Windows.Controls.Primitives;assembly=WPFToolkit"

I get errors about the assembly not being found.
More problems with the rest of the XAML-code.

<Style TargetType="{x:Type primitives:DataGridColumnHeader}">
<Setter Property="ContentTemplate">
    <Setter.Value>
        <DataTemplate>
            <TextBlock TextWrapping="Wrap" Text="{Binding}"></TextBlock>
        </DataTemplate>
    </Setter.Value>
</Setter>
</Style>

I place this inside the DataGrid tag, otherwise it won’t compile. I also omit the “primitives”-namespace as I did not actually include it (see above). Now it compiles. However the application throws some exception in the constructor of the window. Any idea how I can get this thing to actually work?
