Assembly: System.Web (in System.Web.dll)

The following code example demonstrates how to override the OnAttributeRender method to check whether a size attribute is rendered for any of the elements that are rendered by this text writer. If a size attribute is rendered, the code checks whether its value is 8 point. If so, the OnAttributeRender method returns true, allowing the attribute and its value to render. If the value is other than 8 point, the OnAttributeRender method returns false, and the attribute and its value are not rendered. If the key parameter of the OnAttributeRender method does not match the Size attribute, the base functionality of the OnAttributeRender method is called, as defined in the XhtmlTextWriter class.
This code example is part of a larger example provided for the XhtmlTextWriter class.
