    text
    copied!<p>I am wandering if anyone could help me work out the binding issues I am having?</p> <p>Snippets of Code:</p> <pre><code>&lt;DataGrid AutoGenerateColumns="False" Grid.Column="1" Grid.Row="1" SelectionMode="Single" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" ItemsSource="{Binding PersonList}" CanUserSortColumns="True" SelectedItem="{Binding Path=SelectedPerson}" &gt; &lt;DataGrid.Columns&gt; &lt;DataGridTextColumn Header="FirstName" Width="100" Binding="{Binding FirstName}" /&gt; &lt;DataGridTextColumn Header="LastName" Width="100" Binding="{Binding LastName}" /&gt; &lt;DataGridTemplateColumn Width="140" Header="Operator"&gt; &lt;DataGridTemplateColumn.CellTemplate&gt; &lt;DataTemplate&gt; &lt;ComboBox ItemsSource="{Binding Path=OperatorList}" DisplayMemberPath="FullName" SelectedValue="{Binding Path=SelectedOperator}" /&gt; &lt;/DataTemplate&gt; &lt;/DataGridTemplateColumn.CellTemplate&gt; &lt;/DataGridTemplateColumn&gt; ... &lt;/DataGrid&gt; </code></pre> <p>Above is a snippet of code from the view:</p> <p>Each person in the list is its own viewmodel that has the code snippet below:</p> <pre><code>CollectionView _operatorList; public CollectionView DebtorAgentList { get { return _operatorList; } } Model.Operator _selectedOperator; public Model.Operator SelectedOperator {...} </code></pre> <p>Now the problem I am having is that the SelectedValue binding isn't working and I can't work out why? But what makes it tricky or different (maybe) is that every row in the data grid has its own viewmodel , so in otherwords a datagrid of viewmodels. So what is happening is that FirstName and LastName and Combobox are all filled correctly but I can't seem to get the SelectedValue to bind? P.S. It isnt because of some spell mistake, if there are spelling mistakes is because i renamed methods when I wrote the question etc.</p> <p>Further Details:</p> <p>The above Datagrid is part of a view that has its own viewmodel, this view model fills the datagrid above with a list of people, each person is a viewmodel in essence( well it isn't really a viewmodel but then again its more of a viewmodel than a plane model). It works the way I need it to until I try to bind the SelectedView attribute?</p> <p>Could someone please tell me why that binding might not working?</p> <p>Thanks In advance :D</p>
