Hi

I have a UserControls with 20 buttons, how do i create a single delegate for
all these buttons for the click event, which will show in the hosted windows
form.

Pointer to source will be helpful

Regards
Jacko

Click to expand...

Create a subroutine to handle all the buttons:

private sub ClickSub _
(ByVal sender as System.Object, ByVal e as System.EventArgs)
MessageBox.Show("Here...")
end sub



Then in the form constructor, you do the following for all buttons:

AddHandler Button1.Click, AddressOf ClickSub


I don't know what the fragment of your question "...which will show in the
hosted windows form" means.

Hello, Jacko,

If I understand the question correctly...

You need to define a common click Event for your UserControl and raise this
event in the event handler(s) for the buttons. For example:

Public Class MBUserControl

Public Event ButtonClick(ByVal sender As System.Object, ByVal e As
System.EventArgs)

Private Sub Button_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) _
Handles Button1.Click, Button2.Click,
Button3.Click, Button4.Click
RaiseEvent ButtonClick(sender, e)
End Sub

End Class

And then when you add this UserControl to a Form, you can handle the
ButtonClick event. For example:

Public Class Form1

Private Sub MbUserControl1_ButtonClick(ByVal sender As Object, ByVal
e As System.EventArgs) _
Handles
MbUserControl1.ButtonClick
Dim cmdSender As Button = DirectCast(sender, Button)
MsgBox("Button """ & cmdSender.Name & """ was clicked.")
End Sub

End Class

Cheers,
Randy
