I would like to show my user control inside row details. 

I have a complex data structure and cant show all items(just a few) inside datagrid, so I would like to open another control and show it inside row details. I had previously created(designed) it. I'm not creating it dynamicaly.

Is there any way how to achieve it? 

I am working with C# and WPF and developing desktop app.

I would like to be able to use it like:

```
    <DataGrid.RowDetailsTemplate>
        <DataTemplate>
        //    <StackPanel Orientation="Horizontal" Margin="20,0,0,0">
        //        <TextBlock Text="Category:" FontWeight="Bold"/>
        //        <ComboBox IsEditable="True" 
        //                  ItemsSource="{Binding Source={x:Static Data:CheckBook.Categories}}" 
        //                 Text="{Binding Category}" />
        //     </StackPanel>
        <MyControl ItemsSource="blabla">
        </DataTemplate>
    </DataGrid.RowDetailsTemplate>  

```
