Hi,
You will need to use plain HTML. For example, you can do:
Code: C#
SlideMenu1.Items[0].Text.Html =
string.Format("List of products ({0})", productCount);
If you wish to place a text box in it, you can set the item's text to:
Code: HTML/ASPX
<input type="text" name="some_name" />
Note that you must give it a unique name, otherwise you have no way of accessing it on the server side. You would access it on the server side by:
Code: C#
string text = Request.Form["some_name"];
Note you can't use regular ASP.NET server control syntax such as "some_name.Text" because "some_text" is a regular HTML element, not a server control.
Hope this helps.
Thanks!
