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

Parameter (
	Parameter^ original
)
protected Parameter (
	Parameter original
)
protected function Parameter (
	original : Parameter
)
Not applicable.

Parameters

original

A Parameter instance from which the current instance is initialized.

The Parameter(Parameter) constructor is a protected copy constructor used to clone a Parameter instance. The values of the Name, Type, DefaultValue, Direction, and ConvertEmptyStringToNull properties are all transferred to the new instance.

The following code example demonstrates how to call the Parameter(Parameter) constructor from a class that extends the Parameter class to implement correct object cloning behavior for the class. This code example is part of a larger example provided for the Parameter class overview.

No code example is currently available or this language may not be supported.
// The StaticParameter copy constructor is provided to ensure that 
// the state contained in the DataValue property is copied to new
// instances of the class. 
protected StaticParameter(StaticParameter original)
{
    super(original);
    set_DataValue(original.get_DataValue());
} //StaticParameter


// The Clone method is overridden to call the 
// StaticParameter copy constructor, so that the data in 
// the DataValue property is correctly transferred to the 
// new instance of the StaticParameter.
protected Parameter Clone()
{
    return new StaticParameter(this);
} //Clone
