Question

I load a piece of html which contains something like:

 <em> < input type="text" value="Untitled" name="ViewTitle" id="ViewTitle" runat="server"> </em>

into my control. The html is user defined, do please do not ask me to add them statically on the aspx page.

On my page, I have a placeholder and I can use

LiteralControl target = new LiteralControl ();

// html string contains user-defined controls
target.text = htmlstring

to render it property. My problem is, since its a html piece, even if i know the input box’s id, i cannot access it using FindControl("ViewTitle") (it will just return null) because its rendered as a text into a Literal control and all the input controls were not added to the container’s control collections. I definitely can use Request.Form["ViewTitle"] to access its value, but how can I set its value?

Answer 1

Jupaol’s method is the prefer way of adding dynamic control to a page.

If you want to insert string, you can use ParseControl.

However, it doesn’t cause compilation for some controls such as PlaceHolder.
