I need to dynamically add an html control to a web form.
What I have, thus far, adds the control to the page, but only places it
after the closing "</html>" tag.
System.Web.UI.H tmlControls.Htm lInputHidden h = new HtmlInputHidden ();
h.ID = "FIELD1";
h.Value = "Value1";
Page.Controls.A dd (h);
Is there a way to have the control added inside the "<form>" tags?
Thanks,
Scott Natwick 6 2251
I found an example that may help, but I haven't been able to get it to work.
The example suggests obtaining a reference to the Form, then adding the
control the From.
Page.FindContro l("form1").Cont rols.Add(btnDyn )
<form id="form1" runat="server">
</form>
I tried this, but I receive an error when trying to access the Form.

Just change the form tag into an HTML Control (by adding
runat="server" and id="form1".
Then use form1.Controls. Add(h) instead of Page.Controls.A dd(h)

Thanks Jos for the reply!
I did try what you suggested, however I'm still having difficulty on two
counts.
First, I'm not able to add the "runat="server" ". When I do, the form button
Submit does not seem function. I have an "action="http.. ."" in the form tag
as I need the form to submit data to another site. When I add the
runat="server" to the form tag, the Submit button does not trigger a trasfer
to the other page.
Second, I wasn't able to successfully reference the "form1" in the code. I
just receive a compile error.
Does this make sense?
Thanks again.

Thanks for your help. This might be a hack, but I think I found something
that works.
I added a label to the form, then added the new control to the label.
<asp:Label id="Label1" runat="server"> </asp:Label>
System.Web.UI.H tmlControls.Htm lInputHidden h = new HtmlInputHidden ();
h.ID = "FieldId";
h.Value = "Value";
Label1.Controls .Add (h);

If I remember correctly, using the <asp:Label> control will render a <span>
tag to the client. If you don't want to render any html to the client and
still designate a certain place in the web you would like to dynamically add
controls to then I would use the <asp:PlaceHolde r> control instead of the
<asp:Label> control.

Chris,
Thank you for your suggestion -- it was a good one!.
Using the Label tag did create a <span> tag and changing to the PlaceHolder
did not.

Hi,
I have the need to use dynamically loaded user controls in a webform page.
I have the controls loading dynamically, and that part works fine. this is
the code used in a webform to dynamically load one of several controls:
private void btnCategory_Click(object sender, System.EventArgs e)
{
Control myControl = LoadControl(DropDownList1.SelectedItem.Text +
".ascx");
PlaceHolder1.Controls.Add(myControl);

It involves dynamically adding controls to a Table control that is built as a result of performing a database query.
