[*resolved] table control doesnt save its content?

[MrPolite]

ok works, just wondering if it's akward programming to do this

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        ' Force another btnPreview_click 
        If pnlPreview.Visible Then btnPreview_Click(Nothing, Nothing)
    End Sub
 
    Private Sub btnPreview_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPreview.Click
        pnlPreview.Visible = True
 
        ' Generate controls in the panel
        ' ....
    End Sub
