[Solved] Reusing RadMenuItems

[Stefan Lorenz]

Hi,

I'd like to know if there's a way to "link" items from a RadContextMenu to a RadMenu or vice versa. I want to show the same menu-structure from my contextmenu in the main menu without duplicating everything.

I tried to initialize a context with myMainMenuitem.DropDown. While this works (contextmenu with items from myMainMenuitem shows up), the Items of myMainMenuitem were empty afterwards.

Best regards
Stefan

Hi Stefan,

I've tried a really basic example of this and it seems to work. I added a RadContextMenu to a RadListControl and the same menu items to the RadMenu.

On my form, I have a RadMenu, a RadListControl and a RadtextBox. See screenshot.

Imports Telerik.WinControls.UI

Public Class Form1


    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Me.RadMenu1.Items.AddRange(GetMenuItems().ToArray())
        Dim contextMenu As New RadContextMenu()
        contextMenu.Items.AddRange(GetMenuItems().ToArray())

        Dim radContextMenuManager As New RadContextMenuManager()
        radContextMenuManager.SetRadContextMenu(Me.RadListControl1, contextMenu)
    End Sub

    Private Function GetMenuItems() As List(Of RadMenuItem)
        Dim menu1 As New RadMenuItem("Menu Item 1")
        Dim menu2 As New RadMenuItem("Menu Item 2")

        AddHandler menu1.Click, AddressOf Menu1_Click
        AddHandler menu2.Click, AddressOf Menu2_Click

        Dim menus As New List(Of RadMenuItem)
        menus.Add(menu1)
        menus.Add(menu2)
        Return menus
    End Function

    Private Sub Menu1_Click(ByVal sender As Object, ByVal e As EventArgs)
        Me.RadTextBox1.Text &= "Menu 1 Clicked" & Environment.NewLine
    End Sub

    Private Sub Menu2_Click(ByVal sender As Object, ByVal e As EventArgs)
        Me.RadTextBox1.Text &= "Menu 2 Clicked" & Environment.NewLine
    End Sub

End Class

hope that helps

Hi Richard,

you duplicated the menuitems. While this is doable, it means that I either have to create that menus from code or deep-clone existing ones. I thought there must be a solution to show an existing menu as a context without duplicating it.

Hi Stefan,

I may be wrong, but I think the problem there will be that each RadMenuItem needs to have an owner. So which will teh ownder be, the RadMenu or the RadContextMenu.

Hi Stefan, 

Thank you for writing.

Richard is absolutely right in his last post. One menu item cannot be parented by two or more parents at the same time.

Thank you Richard for the community effort.  

If there is anything else I can assist you with guys, do not hesitate to contact me.

Kind regards,
