Hi All, Easiest to explain if I show an example: I have a DataGridView which has a column that is a combo box. I have a dataset as the source, it has two columns: FirstName and LastName. I want the combo box to display "LastName, FirstName", ie, I want the display member to be a combination of two columns. Is this possible? Or will I have to add a new column to my dataset "FullName" which will be the two added together? Cheers, Brad
