Assembly: System.Web (in System.Web.dll)
A ControlParameter object that is created with the ControlParameter constructor is initialized with default values for all its properties. The ControlID and PropertyName properties are initialized to String::Empty. In addition, the Name property is initialized to String::Empty, the Type property is initialized to TypeCode::Object, the Direction property is initialized to Input, and the DefaultValue property is initialized to null.
The following code shows how to create a ControlParameter object with the ControlParameter constructor. The ControlParameter object binds the SelectedValue property of a DropDownList control to a parameterized SQL query that retrieves data that is displayed in a DataGrid control.
