    <p>I have and DataGridComboBoxColumn in the DataGrid a WPF window. I am assigning DataContext to Window as below:</p> <pre><code>cls = new MyClass { selValue = 2, DataGrid = dtGrid, ComboGrid = dtCombo }; this.DataContext = cls; </code></pre> <p>Following is the XAML for DataGridComboBoxColumn:</p> <pre><code> &lt;DataGridComboBoxColumn Header="Item Name" SelectedValueBinding="{Binding Path=Item_Id}" SelectedValuePath="ItemId" DisplayMemberPath="ItemName"&gt; &lt;DataGridComboBoxColumn.ElementStyle&gt; &lt;Style TargetType="ComboBox"&gt; &lt;!-- modified this code as per suggestion ///--&gt; &lt;Setter Property="ItemsSource" Value="{Binding RelativeSource={RelativeSource AncestorType=Window}, Path=DataContext.ComboGrid }" /&gt; &lt;/Style&gt; &lt;/DataGridComboBoxColumn.ElementStyle&gt; &lt;DataGridComboBoxColumn.EditingElementStyle&gt; &lt;Style TargetType="ComboBox"&gt; &lt;Setter Property="ItemsSource" Value="{Binding RelativeSource={RelativeSource AncestorType=Window}, Path=DataContext.ComboGrid }" /&gt; &lt;/Style&gt; &lt;/DataGridComboBoxColu </code></pre> <p>mn.EditingElementStyle> </p> <p>Still Combobox in grid showing blank. No data is being listed in Combobox. Then, I wrote following code in Windows codebehind, it start working.</p> <pre><code>((DataGridComboBoxColumn)this.testGrid.Columns[1]).ItemsSource = cls.ComboGrid.DefaultView; </code></pre> <p><strong>Is there anyway to handle this case in XMAL itself using MVVM? I am reluctant to use this apporache.</strong></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.
