Examples

The following code example shows an overridden CreateWebPartMenu that includes two custom Boolean properties, ParentItemIsVisible and EnableItem1, that allow you to control when these menu items are visible and enabled. It also assumes that this method is part of a Web Part class that includes an event handler named EventHandlerForItem1.

Public Overrides Sub CreateWebPartMenu()
    ' Declare variables for menu items.
    Dim ParentItem As MenuItem
    Dim Item1 As MenuItem
    Dim Item2 As MenuItem
    
    ' Create three menu items:
    ' One parent item, and two submenu items.
    ' Create the parent item.
    ParentItem = New MenuItem("ParentItem", "", "ParentItemID")
    
    ' Create a submenu item with a server event on click.
    Item1 = New MenuItem("Item1", "Item1ID", New EventHandler(AddressOf EventHandlerForItem1))
    
    ' Create a submenu item with a client event on click. 
    Item2 = New MenuItem("Item2", "javascript:alert('Item2 was clicked.');", "Item2ID")
    
    ' Add the submenu items to the parent item.
    ParentItem.MenuItems.Add(Item1)
    ParentItem.MenuItems.Add(Item2)
   
    ' Add the parent item after the "Modify Shared/Personal Web Part"
    ' command in the default menu. 
    ' Retrieve the index of the "Modify Shared/Personal Web Part" 
    ' command.
    Dim EditIndex As Integer = Me.WebPartMenu.MenuItems.IndexOf(Me.WebPartMenu.MenuItems.ItemFromID("MSOMenu_Edit"))
    
    ' Insert the parent item after the "Modify Shared/Personal Web 
    ' Part" command.
    Me.WebPartMenu.MenuItems.Insert(EditIndex + 1, ParentItem)
     
    ' Add a separator above the parent item.
    ParentItem.BeginSection = True
         
    ' Check the "ParentItemIsVisible" custom boolean property to decide 
    ' whether to display the parent menu.
    If Me.ParentItemIsVisible = True Then
       ParentItem.Visible = True
         
    Else
       ParentItem.Visible = False
    End If
         
    ' Check the "EnableItem1" custom boolean property to decide which 
    ' menu item to enable. 
    ' within the parent item.
    If Me.EnableItem1 = True Then
       Item1.Enabled = True
       Item2.Enabled = False
         
    Else
       Item1.Enabled = False
       Item2.Enabled = True
    End If
End Sub

public override void CreateWebPartMenu()
{
    // Declare variables for menu items.
    MenuItem ParentItem;
    MenuItem Item1;

    // Create three menu items:
    // One parent item, and two submenu items.

    ParentItem = new MenuItem("ParentItem", "", "ParentItemID");

    // Create a submenu item with a server event on click.
    Item1 = new MenuItem("Item1", "Item1ID", new EventHandler(EventHandlerForItem1));

    // Create a submenu item with a client event on click. 
    Item2 = new MenuItem("Item2", "javascript:alert('Item2 was clicked.');", "Item2ID");

    // Add the submenu items to the parent item.
    ParentItem.MenuItems.Add(Item1);

    // Insert the parent item after the "Modify Shared/Personal Web 
    // Part" command.

    // Add a separator above the parent item.
    ParentItem.BeginSection = true;

    // Check the "ParentItemIsVisible" custom boolean property to 
    // decide whether to display the parent menu.
    if (this.ParentItemIsVisible == true)
    {
        ParentItem.Visible = true;
    }

    else
    {
        ParentItem.Visible = false;
    }

    // Check the "EnableItem1" custom boolean property to decide which 
    // menu item to enable. 
    // within the parent item.
    if (this.EnableItem1 == true)
    {
        Item1.Enabled=true;
        Item2.Enabled=false;
