Using events with controls created in code.

[Shawn]

Hello All,

I am trying to raise enter events for a combobox control that I am building
dynamically at run time. A user enters a number in a textbox and that many
comboboxes are created. I then need to populate them with a database query,
but can seem to find a way to get any more than the last control to respond.
I have them being named differently, but only the base name shows for
events. Below is my code...

Dim WithEvents ctlComboBox As Control

Private Sub frmAddPeopleToG roup_Load(ByVal sender As System.Object, ByVal e
As System.EventArg s) Handles MyBase.Load
CreateControls( )
MakeTable()
End Sub
Private Sub CreateControls( )
Static LocationStart As Integer = 50

Dim vbFont As New Font("Baskervil le Old Face", 10)
Dim i As Integer

For i = 0 To frmAddGroup.vbP eopleCount - 1
ctlComboBox = New ComboBox()
With ctlComboBox
.Name = "cmbPeople" & i
.Location = New Point(20, LocationStart)
.Width = 250
.Font = vbFont
End With

LocationStart += 30
Me.Controls.Add (ctlComboBox)
Next
End Sub

Thanks!!

Shawn,

Look at this sample as I once made, the text in it is the same for you.

I hope this helps,

I don't know where my brain went on this one, but your code looks good. I
will adapt it and try it out.

Thanks!!!

Take a look at the 'AddHandler'/'RemoveHandler' statements:

\\\
Private Sub Test()
Dim Button1 As New Button()
With Button1
.Location = New System.Drawing. Point(56, 88)
.Name = "Button1"
.Size = New System.Drawing. Size(144, 48)
.TabIndex = 0
.Text = "Button1"
End With
AddHandler Button1.Click, AddressOf Me.Button_Click
Me.Controls.Add (Button1)
End Sub

Private Sub Button_Click( _
ByVal sender As Object, _
ByVal e As EventArgs _
)
MsgBox("Hello World")
End Sub
