The main goal for this time is to add inline editing functionality to the grid, in order to be able to update the imports and manage adding, editing and removing credit cards.

As first we will add a couple of new methods in our Data Service class.

We will write down methods that will allow us to update, add and remove the credit card entities.

For this situation, many developers use invisible columns (Hidden columns) in the gridview to identify that row.

We can achieve the same functionality using Datakeys.

Because of this, we have our edit controls in read only state.

public static bool Remove Import(int credit Card Id, int year, byte month) public static bool Add Import(int credit Card Id, int year, byte month, decimal import) public static bool Update Import(int credit Card Id, int year, byte month, decimal import) This is it.

No more code is necessary for managing data and we can now comfortably start with the interface. There are several methods for achieving the same result.

A datakey represents the primary key field or field of a record that can uniquely identify it in a data-bound control. Row Index represents the index of the particular row.

Many a times in our applications we use primary keys to get control of the particular record in the gridview. There are also many other modes, you have rich client and server side methods in order to start editing one or more rows.
