Hello,
You must first add control to TabControl.Controls collection:

See code:

  Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    Dim uc As New UserControl1
    AxTabControl1.Controls.Add(uc)
    AxTabControl1.InsertItem(0, "Item", uc.Handle.ToInt32(), -1)
  End Sub

Hi !

I have used tabcontrol  of codejock, and I used usercontrol for every tab page of the tab contorl. I saw that when the form with tabcontrol is loaded, the load event of the forms that are used from the tabpages are invoked twice !?!?!

The constructor of the form is executed only one time, but the form_load event is invoked twice...This with vb.net (2005)...

And another thing -  I saw that one event DobuleClick in DataGridView in usercontrol that is used in tabpage is invoked 3 times, when i only one time double clicked on datagridview...

Where is the problem ?
