and the country is a WebCombo that takes data from a database (e.g. all the countries). The thing that I want to do is when the grid is initialized, each webcombo has default value, the value that it is stored in the database. For example:

This is certainly possible. The following link will show you how to do so:

When you select a value from the combo, it becomes the cell's value; therefore, you can persist this change to the database.
