SessionParameter::SessionField Property
Gets or sets the name of the session variable that the parameter binds to.
Assembly: System.Web (in System.Web.dll)
Property Value
Type: System::String^A string that identifies the HttpSessionState that the parameter binds to.
The SessionField property identifies a name/value pair that is stored in the current session object associated with the Web browser. While the SessionField property identifies the name of the pair, the SessionParameter binds to its corresponding value at run time. If the expected session string name/value pair is not found in the session, 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 create a SessionParameter object, set its Name, SessionField and DefaultValue properties, and add it to the SelectParameters collection of a SqlDataSource control. A GridView control displays the results of the SQL query submitted by the SqlDataSource control.
The following code example demonstrates how to programmatically set the SessionField property of a SessionParameter object.
