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.
You can change this easily be creating your own database and changing the connection string in the web config.
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.
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.
In case the user hits Escape key (27) we will just get out of the edit mode by calling Cancel Edit method.
