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

public:
QueryStringParameter (
	String^ name, 
	String^ queryStringField
)
public QueryStringParameter (
	String name, 
	String queryStringField
)
public function QueryStringParameter (
	name : String, 
	queryStringField : String

Not applicable.

Parameters

name

The name of the parameter.

queryStringField

The name of the query string field that the parameter object is bound to. The default is Empty.

A QueryStringParameter object created with the QueryStringParameter constructor is initialized with the specified parameter name and string that identifies the query string field that the parameter binds to. Other properties, including Type and Direction, are initialized with default values.

The following code example demonstrates how to create two QueryStringParameter objects with the QueryStringParameter constructor and add them to an AccessDataSource control's SelectParameters collection. A GridView control displays data if the "employee" and "country" query string fields are passed on the query string with valid values.
