Registers markup attributes, whether literals or dynamically generated, from the source file so that they can be properly rendered to the requesting client.
Namespace: System.Web.UI Assembly: System.Web (in system.web.dll)
The predefined attributes of the HTML markup language are registered by calls to the RegisterAttribute method when the first HtmlTextWriter object is created. Dynamic attributes can be registered by using the RegisterAttribute method at other times.
The registration table used by the RegisterAttribute method is static, so registration of attributes applies to all HtmlTextWriter objects on the host computer.
