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.
 public sealed class SimpleControl : WebControl 

      private String UserMessage=null;

      // Create a property named ControlValue.
      public String ControlValue 
            return UserMessage;
            UserMessage = value;

      protected override void Render(HtmlTextWriter output) 
        output.Write("Testing the ConstructorNeedsTagAttribute class.");
