Datagridview With Combobox Column

I currently have an application that has a working Datagridview that is set up to do what I need. I have recently been asked to add a new column that has dropdown values in it and that can be added to.

The current setup is I have a datagrid bound to a dataset returned from a table using the datasource property. I need to add a new column at the front of the datagrid, fill it with a stored procedure that returns values from? a SQL Server Database, and allows the user to type in a value which will add it to the dropdown and all the other dropdowns on that column.

I also need to be able to save the value from each Combobox. So row 1 I might select the first item, row 2 the third item, I need to be able to reference those values when I reference the row.

Due to the nature of the application I can't provide the existing code, but I could work out a quick framework that should give you an idea what I need if necessary.

This can't use any third party controls and removing the columns added at design time or drastically modifying the current layout is not an option.

## Deliverables

This is to be done in the .vb format, not in an aspx or web format. The attached file shows basically where I'm at and where I need to get.
