ControlBuilder.ControlType Property
.NET Framework (current version)
Gets the Type for the control to be created.
Assembly: System.Web (in System.Web.dll)
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.
