Determines if the control builder needs to get its inner text. If so, the SetTagInnerText method must be called. This method is called by the ASP.NET page framework.
Namespace: System.Web.UI Assembly: System.Web (in system.web.dll)
The following example uses the InDesigner property when the NeedsTagInnerText method is called. When a control has this builder attached to it, the NeedsTagInnerText determines whether the control is being accessed at design-time through a designer. The NeedsTagInnerText returns the value of the InDesigner property, and then the SetTagInnerText method is called. If the InDesigner property is set to false, an Exception is thrown. Otherwise, the inner text of the control is returned on the SetTagInnerText call.
