Notifies the server control that an element, either XML or HTML, was parsed, and adds the element to the server control's ControlCollection object.
Assembly: System.Web (in System.Web.dll)
The following example is a custom server control that uses the method to determine if elements declared between the opening and closing tags of this control are TextBox Web server controls. If they are, they are added to an ArrayList object, items. When the overridden CreateChildControls method is called, it iterates through the ArrayList and adds each object in it to the ControlCollection of the custom server control.
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.
