Examples

The following example shows how to open a submenu of a MenuItem. In this example, the MenuItem called fileMenu contains a MenuItem called recentFiles that has a submenu. When fileMenu is opened, the SubmenuOpened event is raised and the FileMenu_Opened event handler opens the submenu of recentFiles.

<Menu>
 <MenuItem Name="fileMenu"
 Header="_File"
 SubmenuOpened="FileMenu_Opened">

 <MenuItem Name="recentFiles" 
 Header="Recent files">

 <MenuItem Header="file 1"
 IsCheckable="True"/>

 <MenuItem Header="file 2"
 IsCheckable="True"/>
 </MenuItem>
 <Separator/>
 <MenuItem Name="closeMenu" 
 Header="Close all Files"/>
 </MenuItem>
</Menu>

private void FileMenu_Opened(object sender, RoutedEventArgs e)
{
 if (sender == e.Source)
 {
 recentFiles.IsSubmenuOpen = true;
 Keyboard.Focus(recentFiles);
 }
}

Private Sub FileMenu_Opened(ByVal sender As Object, ByVal e As RoutedEventArgs)
 If sender Is e.Source Then
 recentFiles.IsSubmenuOpen = True
 Keyboard.Focus(recentFiles)
 End If
End Sub

Remarks

When IsSubmenuOpen is set to true, mouse capture is set to the MenuItem and its subtree.
