runtime errors. Control '_ctl1' of type 'TextBox' must be placed inside a form tag with runat=server. I am only getting the above errors with anything other than labels. If I use the label sample provided, it works perfectly. Here is the code inside of my class. Public sub Construct_(pg As Page) Dim lbl As New Label() lbl.id = "lblHello" lbl.Text = "Hello" pg.Controls.Add(lbl) Dim lbl2 As New Label() lbl2.Text = "Another Label" pg.Controls.Add(lbl2) Dim _txtbox As New Textbox() _txtbox.Text = "test" pg.Controls.Add(_txtbox) End Sub If I rem out the textbox one, it works just fine.
