CookieParameter.CookieName Property
Assembly: System.Web (in system.web.dll)
/** @property */ public String get_CookieName () /** @property */ public void set_CookieName (String value)
public function get CookieName () : String public function set CookieName (value : String)
Not applicable.
Property Value
A string that identifies the client-side HTTP cookie that the parameter binds to.The CookieName property identifies an HTTP cookie, which is represented by an HttpCookie object and is available through the current HttpRequest object. If the HTTP cookie is not available in the current HttpRequest object, the Evaluate method binds the parameter to the value of the DefaultValue property, if it is set. If the DefaultValue property is not set, the Evaluate method fails to bind the parameter to a value.
The following code example demonstrates how to declaratively use a SqlDataSource control and a CookieParameter object bound to an HTTP cookie to display data from the Northwind Traders database in a GridView control.

The following code example demonstrates how to programmatically create a CookieParameter object, set its properties, and add it to a SqlDataSource control's SelectParameters collection.
CookieParameter cookieParam = new CookieParameter();
cookieParam.set_Name("lastname");
cookieParam.set_Type(System.TypeCode.String);
cookieParam.set_CookieName("lname");
