Using AddressOf Dynamically

Question

I'm adding buttons to form at runtime using the following code :

Private Sub AddNewButton(ByVal btnName As String, ByVal btnText As String)
    Dim myButtons As New VIBlend.WinForms.Controls.vButton

    With myButtons
        .Size = New Size(200, 60)
        .Visible = True
        .Location = New Point(55, 33)
        .Text = btnText
        .Name = btnName
        .Font = New Font("Times New Roman", 12, FontStyle.Bold, GraphicsUnit.Point)
    End With

    AddHandler myButtons.Click, AddressOf btnName & "_Click"

    btnsPanel.Controls.Add(myButtons)

End Sub

Code works fine but Vb.net doesn't allow me to assign AddressOf a sub procedure using variable AddressOf btnName & "_Click" says AddressOf operand must be the name of method, the problem is I don't know which button is going to be created and which procedure is it going to call, I want to assign AddressOf procedure using variable Is it possible or do I have any other choice ?

Answer 1

You can (and should) use the same event handler for all of the buttons.

AddHandler myButtons.Click, AddressOf btn_Click

You can get the name in the handler in this way:

Private Sub btn_Click(sender As Object, e As EventArgs)
    Dim button = DirectCast(sender, Button)
    Dim name As String = button.Name ' you can also use the Tag property
End Sub
