Overridden to allow only literal controls to be added as the Text property.
Assembly: System.Web (in System.Web.dll)
| Exception | Condition |

| HttpException | obj is not of type LiteralControl. |
The following code example demonstrates how to override the AddParsedSubObject method in a custom server control so that it always sets the Text property to the parsed object's Text property if the parsed object is a Literal control, and throws an exception otherwise.

This example has a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview. |
