I will not waste space in this post so I will show you only what you would need to add.
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.
Last but not least you will need the 12.2.5 version of Dev Express ASP. If you do have a more recent version, upgrading the project should be easy.

In case the user hits Escape key (27) we will just get out of the edit mode by calling Cancel Edit method.
Once Update Edit is called a callback will be generated and the Row Updating server side method will be executed, in which we will need to handle the persistence of the data.
Still there are a couple of tricks that we will see in the following lines.
In order to start editing a certain row, we can choose the way we are going to start this action.
The attached project is written in Visual Studio 2012. Also you will need a Microsoft SQL Server 2012, Express or and more advanced version will be just fine.
As first, we are indicating the cell as read only, after that we are casing the control to an ASPx Text Box (which is the right control for these columns) and setting several parameters in order to make the editing look proper.
The most important thing is that we are assigning to each of editing cells a client side event Key Down, in which we will manage the persistence. If Enter (13) key is pressed meanwhile we are in one of editing cells, we will prevent the defaults for this action and call Update Edit method on our grid.
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.
If you are interested in more you can check this Grid Editing – Edit Modes A rich set of editors for different column types allows column values to be modified with ease.
Because of this, we have our edit controls in read only state.
