Hi,

Can someone tell me how I start an event automatically when I change an item
in a combobox, which is in a usercontroller.

I tried the following but it doesn't work;

ComboBox UserController;

Public Class ucComboBox
Public Event Start()

#Region " Windows Form Designer generated code " ..........

Protected Overridable Sub ComboBox_SelectedIndexChanged(ByVal sender As
System.Object, ByVal e As System.EventArgs) Handles
ComboBox.SelectedIndexChanged

RaiseEvent Start()

End Sub

End Class

Main form;
Public Class form1

Friend WithEvents MySender As ucComboBox

#Region " Windows Form Designer generated code " ..........

Private Sub MySender_Start() Handles MySender.Start

MsgBox("Do something!")

End Sub

End Class

Not too fimiliar with user controls but calling

MyBase.OnSelectionChangeCommitted(EventArgs.Empty)

in my inherited combobox forces the event to fire for anyone handling
the event.

wrambel,

Why do you want to raise an event when you just can call the sub that
handles that event?

Myevent(nothing,nothing)
Myevent(me,nothing)
Myevent(TheControl,nothing)
and a lot more

I hope this helps,
