ControlParameter Constructor (String, TypeCode, String, String)

Initializes a new named and strongly typed instance of the ControlParameter class, using the specified property name and control name to identify which control to bind to.

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

public ControlParameter(
	string name,
	TypeCode type,
	string controlID,
	string propertyName
)

Parameters

name
Type: System.String
The name of the parameter.
type
Type: System.TypeCode
The type that the parameter represents. The default is TypeCode.Object.
controlID
Type: System.String
The name of the control that the parameter is bound to. The default is String.Empty.
propertyName

A ControlParameter object that is created with the ControlParameter constructor is initialized with the specified parameter name, Type, Control name, and PropertyName property. Only the Direction and ConvertEmptyStringToNull properties are initialized with default values.

The following code shows how to use the ControlParameter constructor to create two ControlParameter objects and associate them with a SqlDataSource control.



  ControlParameter country =
    new ControlParameter("country",TypeCode.String,"ListBox1","SelectedValue");
  sqlSource.SelectParameters.Add(country);

  ControlParameter report  =
    new ControlParameter("report",TypeCode.Int16,"ListBox2","SelectedValue");
  sqlSource.SelectParameters.Add(report);
