Post Back and HTML Controls

[Chris]

Hello.

I had a question that I was hoping someone might be able
to answer.

I have an ASP .NET Web Form with a custom control that
generates HTML based on certain criteria.

This control is on the web form. For example the control
will generate a question with an HTML input text box.

When my web form does a post how do I get the contents of
this text box?

When I do request.form.item("txtTextBox") it returns
nothing.

In the HTML of the web form the input text box shows-up
but I can't obtain the contents. Does someone know what
I'm doing wrong?

Thanks for your time,
Chris

It's a custom control. Only you know how you wrote it to work.

it depends on how you rendered the html text box.

if you rendered the html yourself, you must include a unique name attribute
that can be used to look it up in the form collection.

if you added a html text box control, it assigned a unique name based on the
id you gave it. generally
<your controls id>:<textbox id>
if you regen the control on postback (before form load), you can just ask
the subcontrol for its value.

on the control render I write out HTML
Protected Overrides Sub Render(ByVal output As
System.Web.UI.HtmlTextWriter)
If Me.Action = "register" Then
output.Write(getHTML)
ElseIf Me.Action = "confirm" Then
output.Write(getConfirmHTML)
End If
End Sub

The HTML that gets written is:
..Append("<TR><TD>")
..Append("&nbsp&nbspWhat is your clients's last name?
&nbsp&nbsp" & "</TD>" & vbCrLf)
..Append("<TD><INPUT id=" & """txtClientsName""" & "
type=" & """text""" & "><BR></TD></TR>" & vbCrLf)

simple question with a text box

My question is do I need to add a property within the
control to save the value or once the HTML is written to
the screen it now becomes part of the web form.

I'm trying to understand the process so I can obtain the
value of the control text box field.

Web form -> control -> write HTML output -> becomes part
of Web form and is rendered within table -> on post what
do I need to do to obtain the value?

Thanks

Thanks I figured out my mistake. It needs a name property
along with id.
