Hi 

I'm using .net 2.0 and vb.net , web forms

On my master page there is a radmenu. This menu has 4 buttons that if you hover over any of them then , then a drop down will appear. and each drop down has 1 to 5 buttons.  example below

......home...... menu1........menu 2.......menu3.....menu4
                      a                 t                  s             v
                      b                                    w                    
                      c                                    q
                      d
                      e


my question is:

from the code behind on my .aspx page, how do I disable "menu1" and all its buttons.

I still want to see it  but just it must not link.

right now I have this   


Partial Class _Default
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load

Me.FindControl("Mymenu").Visible = True

          'how do I disable "menu1" and all its buttons.

        Dim m As Telerik.Web.UI.RadMenu = CType(MyBase.Master.FindControl("Mymenu"), Telerik.Web.UI.RadMenu)

        m.item find("menu1").Disable()


    End Sub
End Class

Hi,

Please try the following code snippet that I have tried to disable a RadMenuItem from Code behind.

VB:
Protected Sub Page_Load(sender As Object, e As EventArgs)
    Dim menu As Telerik.Web.UI.RadMenu = DirectCast(MyBase.Master.FindControl("RadMenu1"), Telerik.Web.UI.RadMenu)
    menu.FindItemByText("Menu1").Enabled = False
End Sub

Thanks,
Shinu.

Thanks for the reply but I get an error saying that 

Object reference not set to an instance of an object.

and it is not happy with this line  menu.FindItemByText("Menu1").Enabled = False

the name "Menu1" is correct


Thanks for your help
