Sample of simple use of datagridview with a column which is a dropdown

[Lloyd Sheen]

I have been trying for last couple of hours, googling etc to find how to use
a simple one column datagridview where the one and only column is a dropdown
combobox.

I have not been successful , I have tried virtual and other methods but
nothing is working.

I am binding a simple list(of string) to the datagrid and want first that
the number of entries in the datagrid be the number of items in the list.
Secondly that each dropdown will hold a list of possible entries which is
derived at run time and lastly that the selected item be shown correctly.

I cannot get this work.

thanks
