ParameterCollection.Item Property (String)

Note: This property is new in the .NET Framework version 2.0.

Gets or sets the Parameter object with the specified name in the collection.

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

public:
property Parameter^ default [String^] {
	Parameter^ get (String^ name);
	void set (String^ name, Parameter^ value);
}
/** @property */
public Parameter get_Item (String name)

/** @property */
public void set_Item (String name, Parameter value)

JScript supports the use of indexed properties, but not the declaration of new ones.

Parameters

name

The Name of the Parameter to retrieve from the collection.

Property Value

The Parameter with the specified name in the collection. If the Parameter is not found in the collection, the indexer returns a null reference (Nothing in Visual Basic).

Use this indexer to get a Parameter object by name from the ParameterCollection collection, using array notation.

The following code example demonstrates how to use the Remove method and the Item indexer to remove a Parameter object from a ParameterCollection collection. In this example, several QueryStringParameter objects are added to a SelectParameters collection, one QueryStringParameter is removed from the collection, and the order of the collection is printed when the page loads.

No code example is currently available or this language may not be supported.
