ConstructorNeedsTagAttribute Constructor

Initializes a new instance of the ConstructorNeedsTagAttribute class.

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

public ConstructorNeedsTagAttribute()

 // Attach the ConstructorNeedsTagAttribute to the custom 
 // SimpleControl, which is derived from WebControl. When 
 // this version of the constructor is used, the NeedsTag 
 // property is automatically set to false; therefore, 
 // this class does not need a tag attribute.
