vb.net control button in popup

Question

I'm new to programming and I need help with something really basic..

I have a form with a datagridview and an "insert" button that opens a popup window (new form). This popup contains labels and textboxes, and 2 buttons (insert & cancel). How do you add event handlers to the buttons inside the popup? For example, if the user clicks "Cancel", the popup should close.

Here's the code I have so far:

Public Sub InsertButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles InsertButton.Click

    Dim insertPopup As New Form
    insertPopup.Size = New System.Drawing.Size(300, 400)
    insertPopup.StartPosition = FormStartPosition.CenterScreen
    insertPopup.Show()

    Dim acceptButton As New Button
    Dim cancelButton As New Button

    acceptButton.Location = New System.Drawing.Point(100, 325)
    acceptButton.Text = "Insert"
    acceptButton.Size = New System.Drawing.Size(85, 24)
    acceptButton.TabIndex = 1

    cancelButton.Location = New System.Drawing.Point(190, 325)
    cancelButton.Text = "Cancel"
    cancelButton.Size = New System.Drawing.Size(85, 24)
    cancelButton.TabIndex = 2

    insertPopup.Controls.Add(acceptButton)
    insertPopup.Controls.Add(cancelButton)

End Sub

Thanks for your help.

You use the AddHandler Method to add the proper EventHandler. You will need to be sure to create your handler with the correct signature.

AddHandler acceptButton.Click, AddressOf acceptButton_Click
AddHandler cancelButton.Click, AddressOf cancelButton_Click

Private Sub acceptButton_Click(sender As System.Object, e As System.EventArgs) 
End Sub

Private Sub cancelButton_Click(sender As System.Object, e As System.EventArgs) 
    CType(CType(sender, Button).Parent, Form).Close()
End Sub
