Win XP - VS 2002 - VB - web forms
I'm creating a table, 2 labels, 1 text box dynamically (only show 1 of each
in code below)
I'm able to add the labels to the table at run time however I cannot add the
text boxes.
here is the code and then the error message,

Dim tblVD As New Table()
tblVD.Visible = True
tblVD.BackColor = Color.Ivory
tblVD.GridLines = GridLines.Both
Me.Controls.Add(tblVD)

Dim rforloop As Int16

For rforloop = 0 To 4
Dim trow As New TableRow()
For cforloop = 0 To 3
Dim tcell As New TableCell()
trow.Cells.Add(tcell)
Next cforloop
tblVD.Rows.Add(trow)
Next rforloop

Dim lab As New Label()
lab.Text = "lab"
tblVD.Rows(0).Cells(0).Controls.Add(lab)

Dim txt As New TextBox()
txt.BorderStyle = BorderStyle.Groove

Hi Tony,

You're adding the table to part of the page but forgetting that the form is
just one child control of the page. If you check with trace="true", you'll
see that to put the table inside the form, you need to go to the second
control (1 in zero-based counting):

Page.Controls(1).Controls.Add(tblVD)

The table seems to be able to survive outside of the form (that's where it
was going) but the textbox can't.

An easier way to do this would be to drop a Placeholder onto the page and
then add things to the Placeholder's controls collection.

Let us know if this helps?

I'm using your suggestion
Page.Controls(1).Controls.Add(tblVD) (not sure how the placeholder
control works)
All worked well until I hit a button and caused a postback then table and
controls disappeared.
I have the creation of all the controls and table in the Load page in a if
not is postback.

Also I'm unable to use the control except for in the load_page .
for example I have dim txt as textbox() , then I add txt.text = "thanks for
your help".
then I created a button1 on the design page, if I try to put code in it like
if txt.text = "thanks for your help" I get an error txt not declared. But it
is in the page_load sub.


Thanks
Tony
