ControlBuilder.HasBody Method

Determines if a control has both an opening and closing tag. This method is called by the ASP.NET page framework.

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

public virtual bool HasBody()

Return Value

Type: System.Boolean
true if the control has an opening and closing tag; otherwise, false.

This method is called by the ASP.NET page framework during parsing and is not intended to be called directly in you code.

This example overrides the OnAppendToParentBuilder method to check the ControlType property to determine what type of control this builder is applied to. If it is a CustomTextBox, the builder checks whether the value of the HasAspCode property is included in the control. If so, an exception is thrown, if not the HasBody method is called.

            // ASP code blocks exist in the control. If so, call 
            // throw an Exception, if not, call the HasBody method.
