Enable/Diable menu items on Parent Form from Child Form

Though I would think this would be easy..

I have a windows VB 2010 mdi application.

The parent form has a menu on it that we want to have all entries disabled when start.

Based on a login from a child form, I need to enable certain items on that menu based on the login credentials.

How can I access the menu control on the parent form from the child form on a button click on the child form.

THanks!

One way is to cast the MdiParent() property to the correct type that your main MDI parent is.

For example, if your MDI parent was of type "frmMain" and it had a menu on it called "AdminToolStripMenuItem":

Public Class frmChild

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim main As frmMain = DirectCast(Me.MdiParent, frmMain)
        main.AdminToolStripMenuItem.Enabled = True
    End Sub

End Class

I suggest not using mdi child for login but dialog form instead. In this case enable 1 menu item ("mnuLogin") in main form and handle click event:

Using f As New frmLogin
    If f.ShowDialog(Me) = Windows.Forms.DialogResult.OK Then
        'Your logic to enable menu items in main form
    End If
End Using
