Dynamic, Run-Time Insertion of Controls

[Guest]

I want to be able to create and insert an ASP.NET control into a page after a
control that already exists on that page at Run-Time. I'm pretty sure that
that can be done but I'm not exactly sure what the syntax would be and then
how you access the control after the fact at PostBack, etc.

Hi Alex,

You can put a PlaceHolder control after the existing control and then add
the new (dynamic) control to its Controls collection.

Is this a case where you could create the control a design-time but hide it
(make visible=false) until you need it?

No, I wouldn't be creating it in design-time. Well, actually, the scenario is
that I could create ONE of the controls in design-time, but I may have to
create X controls like that one dynamically at run-time. But I really don't
know how to create the control that way, to set it's event handlers, etc.,
etc.

Hi Alex,

As for the dynamically control creating question you mentioned, would you
provide some further detailed page or code logic or would you use a simple
page to illustrate the requirement in your scenario?

For generice info on dynamically creating ASP.NET web server controls, you
can refer to the following msdn and knowledge base artciles:
