A ControlParameter object 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 example demonstrates how the ControlParameter constructor can be used 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);


ControlParameter country = new ControlParameter("country", 
    System.TypeCode.String, "ListBox1", "SelectedValue");
sqlSource.get_SelectParameters().Add(country);
ControlParameter report = new ControlParameter("report", 
    System.TypeCode.Int16, "ListBox2", "SelectedValue");
sqlSource.get_SelectParameters().Add(report);
