Used to provide design-time support in a visual designer for the System.Web.UI.WebControls.Button Web server control.
See Also: ButtonDesigner Members
In a visual designer, when you switch from Source to Design view, the markup source code that describes the System.Web.UI.WebControls.Button control is parsed and a design-time version of the control is created on the design surface. When you switch back to Source view, the design-time control is persisted to the markup source code and edited into the markup for the Web page.
