    <p>Are you attempting to bind the <code>DataGridComboBoxColumn</code>'s <code>ItemsSource</code> property to an <code>ObservableCollection</code> (PlatformsCollection) or to a Property (Platform)?</p> <p>You should be able to accomplish this with something like..</p> <pre><code>&lt;DataGridComboBoxColumn Header="Platform" ItemsSource="{Binding PlatformsCollection}" SelectedValue="{Binding SelectedPlatform}" DisplayMemberPath="PlatformName"/&gt; </code></pre> <p><strong>You'll need to add another member to your model called SelectedPlatform which will store/update each time the user changes the selected platform.</strong></p> <p>Additionally, you may want to look into using a <code>CellTemplate</code>/<code>CellEditingTemplate</code> combination with a <code>DataGridTemplateColumn</code> for this which looks a bit nicer. The user is only presented with a textbox unless they click into the cell at which point the combobox would appear.</p> <p>The markup for this would be something like</p> <pre><code>&lt;DataGridTemplateColumn&gt; &lt;DataGridTemplateColumn.CellTemplate&gt; &lt;DataTemplate&gt; &lt;TextBlock Text="{Binding SelectedPlatform.PlatformName}"/&gt; &lt;/DataTemplate&gt; &lt;/DataGridTemplateColumn.CellTemplate&gt; &lt;DataGridTemplateColumn.CellEditingTemplate&gt; &lt;DataTemplate&gt; &lt;ComboBox ItemsSource="{Binding PlatformsCollection}" SelectedValue="{Binding SelectedPlatform}" DisplayMemberPath="PlatformName"/&gt; &lt;/DataTemplate&gt; &lt;/DataGridTemplateColumn.CellEditingTemplate&gt; &lt;/DataGridTemplateColumn </code></pre> <p>Hopefully that helps. Let me know if you have any questions.</p>

    1. COYou are right - I tried to bind Property(Platfrom) - binding to PlatformsCollection is a recent change - when I figured out that binding to Platform doesn't work. SelectedPlatform has to be class like Platform? I'm appologise if the questions are stupid - I'm pretty new in WPF and in .NET development - all in all I'm a PHP developer who needs some help:) Regarding the CellTemplate - it looks like really elegant solution, but I have to use this columnt in adition to an exist combobox column or instead of?

    2. COHonestly speaking I don't need to use platform as a class - all I need it provide Platform to Device from the list of 4 item. Does exist any way to create it without all this tricks - some hardcoded list of items which generates dropdown combobox?

    3. COOh, gotcha. Yeah you could simply add the complex type Platform to your device class and set the SelectedValue attribute on the combobox equal to Device.Platform.

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.
