    text
    copied!<p>I am trying to make a context menu show up a list of strings. The app contains a datagrid of people who can be Edited,Deleted and Added to a group. I have a class StudentGroup which are different groups a person can be added (One of the Members of StudentGroup is Name). ViewModel retrieves the full list of groups and puts it inside an Observable Collection. I am trying to make the context menu work such that whenever a user right clicks and hover over Add User to -> it opens a side menuitems that contains the Observable Collections's Name string. </p> <p>This is what I have tried so far by looking up similar questions on StackOverflow, but it hasn't worked for me yet. </p> <p>The XAML:</p> <pre><code>&lt;DataGrid.ContextMenu&gt; &lt;ContextMenu AllowDrop="True" ItemsSource="{Binding Entries}"&gt; &lt;MenuItem Header="Edit" /&gt; &lt;MenuItem Header="Delete"/&gt; &lt;MenuItem Header="Add User to"&gt; &lt;MenuItem.ItemTemplate&gt; &lt;DataTemplate&gt; &lt;TextBlock Text="{Binding Name}" /&gt; &lt;/DataTemplate&gt; &lt;/MenuItem.ItemTemplate&gt; &lt;/MenuItem&gt; &lt;/ContextMenu&gt; &lt;/DataGrid.ContextMenu&gt; </code></pre> <p>XAML Code behind View:</p> <pre><code>private TitleViewMode TVM=new TitleViewMode; public Welcome() { InitializeComponent(); _grid1.ContextMenu.DataContext = TVM; } </code></pre> <p>ViewModel</p> <pre><code>class TitleViewModel { public ObservableCollection&lt;StudentGroup&gt; Entries {get;set;} private List&lt;StudentGroup&gt; sg1 { get; set;} public TitletViewModel() { sg1 = GetGroups(); Entries = new ObservableCollection&lt;StudentGroup&gt;(sg1); } } </code></pre>
