ControlParameter Class
Binds the value of a property of a Control to a parameter object.
Assembly: System.Web (in System.Web.dll)
You can use the ControlParameter class to bind the value of a Control property, such as SelectedValue or SelectedIndex, to a parameter that is used in a parameterized SQL query, business object method, or filtering expression.
The ControlParameter class provides two properties in addition to those inherited from the Parameter class: ControlID and PropertyName. The ControlID property identifies which Control instance to bind to and the PropertyName property identifies the public property of the Control from which the ControlParameter class retrieves a value.
The following code example demonstrates how to use a ControlParameter object to bind data displayed in a ListBox control to the selected value of a DropDownList control in a declarative scenario. The ControlParameter object is added to the SelectParameters collection of the SqlDataSource control on the form, and corresponds to the "@Title" placeholder text in the SelectCommand property.
