    <p>I am in the process of implimenting the MVVC pattern and am having trouble binding a property in the viewmodel from within a DataTemplate within a datagrid. If I have a textblock outside the DataTemplate in the column it works fine (since I am directly referencing the datacontext of the UserConrol, i.e. the VM) however from within the DataTemplate it wont return the plain text property. It will however return a property from the iterated IEnumerable item.</p> <pre><code>&lt;UserControl xmlns:data="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data" x:Class="Timesheet.Silverlight.Modules.Views.HistoryView" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:Commands="clr-namespace:Microsoft.Practices.Composite.Presentation.Commands;assembly=Microsoft.Practices.Composite.Presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:ViewModels="clr-namespace:Timesheet.Silverlight.Modules.ViewModels" x:Name="View"&gt; &lt;StackPanel&gt; &lt;TextBlock Text="{Binding Path=DataContext.testText, ElementName=View}" /&gt; &lt;data:DataGrid Height="280" Width="500" ItemsSource="{Binding TimeSlots}" AutoGenerateColumns="False" &gt; &lt;data:DataGrid.Columns&gt; &lt;data:DataGridTextColumn Header="Allocation Area" Binding="{Binding TimeAllocationArea.TimeAllocationName}" Width="200" /&gt; &lt;data:DataGridTextColumn Header="Start" Binding="{Binding StartTime}" Width="80" /&gt; &lt;data:DataGridTextColumn Header="End" Binding="{Binding Path=DataContext.testText, ElementName=View}" Width="80" /&gt; &lt;data:DataGridTemplateColumn Header="Modify" Width="200" &gt; &lt;data:DataGridTemplateColumn.CellTemplate&gt; &lt;DataTemplate&gt; &lt;StackPanel Orientation="Horizontal"&gt; &lt;TextBlock Text="{Binding Path=DataContext.testText, ElementName=View}" /&gt; &lt;/StackPanel&gt; &lt;/DataTemplate&gt; &lt;/data:DataGridTemplateColumn.CellTemplate&gt; &lt;/data:DataGridTemplateColumn&gt; &lt;/data:DataGrid.Columns&gt; &lt;/data:DataGrid&gt; &lt;/StackPanel&gt; &lt;/UserControl&gt; </code></pre> <p>Is there some sort of problem with the DataTemplate that im ignoring?? Note the "{Binding Path=DataContext.testText, ElementName=View}" works for all elements except the one in the DataTemplate. (Note I know that the 1st Textblock outside the DG doesnt need the ElementName etc but i have just done it this way to prove to myself that its referencing the right thing)</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
