Hi,

I want to add a table to a form, within the table 3 rows, 3 columns (as a
default) and within each cell a webpart. This works ok:

For i = 1 To aantalY
r = New TableRow
For j = 1 To aantalX
c = New TableCell
c.BorderStyle = BorderStyle.Solid
c.BorderWidth = 1
c.Height = 100
c.BorderColor = Drawing.Color.Black
w = New WebPartZone
w.ID = "web" & i & "_" & j
If bNieuw Then
UC = New WebUserControl
UC.ID = "uc" & i & "_" & j
w.Controls.Add(UC) ''''''''' THIS LINE
receiveses the ERROR
End If

c.Controls.Add(w)
r.Cells.Add(c)
Next
Table1.Rows.Add(r)
Next


except that if bNieuw=True the usercontrol cannot be added. I receive

System.Web.HttpException was unhandled by user code
ErrorCode=-2147467259
