on click event for item on a dropdown button control on toolbar

[Curtis]

Somehow I'm just missing something.

I don't know how to catch when a user clicks on an item in a dropdown list
for a dropdown style button on a toolbar.

I create a new app. Form1. Add a toolbar. Add a button and make it's
style dropdown. In the code I create a contextmenu and add three items.

This is all fine. But when I click on one of the menu items I can't figure
out how to know it's been clicked and what menu item it is.

Here's the test code:

Public Class Form1

Inherits System.Windows. Forms.Form

#Region " Windows Form Designer generated code "

Public Sub New()

MyBase.New()

'This call is required by the Windows Form Designer.

InitializeCompo nent()

'Add any initialization after the InitializeCompo nent() call

End Sub

'Form overrides dispose to clean up the component list.

Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)

If disposing Then

If Not (components Is Nothing) Then

components.Disp ose()

End If

End If

MyBase.Dispose( disposing)

End Sub

'Required by the Windows Form Designer

Private components As System.Componen tModel.IContain er

'NOTE: The following procedure is required by the Windows Form Designer

'It can be modified using the Windows Form Designer.

'Do not modify it using the code editor.

Friend WithEvents ToolBar1 As System.Windows. Forms.ToolBar

Friend WithEvents ToolBarButton1 As System.Windows. Forms.ToolBarBu tton

<System.Diagnos tics.DebuggerSt epThrough()> Private Sub InitializeCompo nent()

Me.ToolBar1 = New System.Windows. Forms.ToolBar

Me.ToolBarButto n1 = New System.Windows. Forms.ToolBarBu tton

Me.SuspendLayou t()

'

'ToolBar1

'

Me.ToolBar1.But tons.AddRange(N ew System.Windows. Forms.ToolBarBu tton()
{Me.ToolBarButt on1})

Me.ToolBar1.Dro pDownArrows = True

Me.ToolBar1.Loc ation = New System.Drawing. Point(0, 0)

Me.ToolBar1.Nam e = "ToolBar1"

Me.ToolBar1.Sho wToolTips = True

Me.ToolBar1.Siz e = New System.Drawing. Size(456, 42)

Me.ToolBar1.Tab Index = 0

'

'ToolBarButton1

'

Me.ToolBarButto n1.Style =
System.Windows. Forms.ToolBarBu ttonStyle.DropD ownButton

Me.ToolBarButto n1.Text = "test"

'

'Form1

'

Me.AutoScaleBas eSize = New System.Drawing. Size(5, 13)

Me.ClientSize = New System.Drawing. Size(456, 334)

Me.Controls.Add (Me.ToolBar1)

Me.Name = "Form1"

Me.Text = "Form1"

Me.ResumeLayout (False)

End Sub

#End Region

Private Sub Form1_Load(ByVa l sender As Object, ByVal e As System.EventArg s)
Handles MyBase.Load

Dim cm As New ContextMenu

cm.MenuItems.Ad d("one")

cm.MenuItems.Ad d("two")

ToolBar1.Button s(0).DropDownMe nu = cm

End Sub

End Class

Hi Curtis
What you should be handing is the MenuItem click event , you could create
a separate handler that handles the click on each of the menu items of
your context menu , your handler should be something like that
Private Sub MenuItem1_Click (ByVal sender As System.Object, ByVal e
As System.EventArg s) Handles MenuItem1.Click
MessageBox.Show ("Source Control: " & CType(sender,
MenuItem).Paren t.GetContextMen u().SourceContr ol.ToString)
'If ContextMenu1.So urceControl Is Nothing Then
'MessageBox.Sho w("Yes")
'Else
' MessageBox.Show (ContextMenu1.S ourceControl.Na me)
'End If

End Sub
in this example you see you can get also the source control ( if you are
using the menu with more than one control) . you would know under with
control this item was clicked
Hope this helps
