Question How do you handle a Dynamically Loaded Control's Event?

[fredfrothen]

Hey guys, i'm a learner to vb.net, used to use vb6 a fair bit.
I'm stuck on a small project of mine, i'm loading a heap of buttons at start up and i then need to be able to handle the buttons click event.

For example when the button is clicked i would like a message box to appear displaying that specific buttons 'Text'.

Here's my code so far:

    Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load

        Dim i As Integer
        For i = 0 To 50
            Dim lol As New Button
            Me.Controls.Add(lol)
            lol.Width = 55
            lol.Height = 22
            lol.Text = "W " & i
            If i <= 10 Then
                lol.Left = 0
                If i > 0 Then
                    lol.Top = 25 * i
                End If
            ElseIf i > 10 And i <= 20 Then
                lol.Left = 80
            End If
        Next i

    End Sub

Hi,

You need to use AddHandler to add events to dynamically created objects. Have a look here:-

AddHandler Statement

Hope that helps.

Cheers,

If you use AddHandler to attach an event handler, make sure that you use RemoveHandler to detach the event handler when you're done with the object.
