Can I instantiate a new webcontrol (a TextBox, for example) at runtime?

I would like to do something like:

TextBox := System.Web.UI.WebControls.TextBox.Create;
TextBox.Page  := self;
...
and have a new TextBox in the web page.

But, of course, there ins't any reference of this TextBox in the aspx file, 
so....

Any idea?

Thanks,
Fabricio.

Yup, easy, almost like you did:

TextBox := WebControls.TextBox.Create();
Self.Page.Controls.Add(TextBox);

Not a problem, as long as you add it to the controls list.


Hth,

Hi,
   only a little adding, if you want to assign a method to a button for
example you need to write a method and use Include(<>,<>) directive to
assigne the event andler.
