- Q You create an ASP.NET page that contains a DataGrid control. The control displays data that is retrieved from a database named TestKingDB. You want your users to be able to sort the data in either ascending or descending order. You write code to sort the data in the DataGrid control by using the SortOrder property when a user clicks in a column. The values stored for the SortOrder property are ASC for ascending order, and DESC for descending order. You want to preserver the value during postbacks. A user selects descending order. Which code should you use to save and retrieve the value? A. // Save Application[SortOrder] = DESC; // Retrieve string val = (string) Application[SortOrder]; B. // Save Cache[SortOrder] = DESC; // Retrieve string val = (string) Cache[SortOrder]; C. // Save ViewState[SortOrder] = DESC; // Retrieve string SortOrder = (string) ViewState[SortOrder]; D. // Save Cache[SortOrder] = SortOrder; // Retrieve string val = (string) Cache[DESC];
