LoginViewDesigner.GetEmptyDesignTimeHtml Method
.NET Framework 3.0
Gets the markup that renders a placeholder for the associated control at design time when the current template is not defined.
Namespace: System.Web.UI.Design.WebControls
Assembly: System.Design (in system.design.dll)
Assembly: System.Design (in system.design.dll)
The GetEmptyDesignTimeHtml method first formats a string message that specifies the name of the current template of the associated LoginView control and also specifies that the template is empty. Then the GetEmptyDesignTimeHtml generates the markup for a placeholder containing that message.
The following code example shows how to override the GetEmptyDesignTimeHtml method in a class that is inherited from the LoginViewDesigner class to change the appearance of a control that is derived from the LoginView class at design time. The example generates the markup for a placeholder that includes the names of all the RoleGroup objects that are defined for the associated control.
