How to set a DataGridViewComboBoxCell display value

Question

Hi there I need to know how to set the display value of each DataGridViewComboBoxCell in a DataGridViewComboBoxColumn on the fly where the values may be all different. I am using a dataset as the data source for my DataGridViewComboBoxColumn . The only reference I can find to this anywhere is how to set one display value for the whole column ie. Dim objComboCol as DataGridViewComboBoxColumn objComboCol.DefaultCellStyle.NullValue = "My Display Value". However I need to be able to set each value individually on the fly. I am programming in VB.NET using Visual Studio 2005. Any help would be much appreciated. Andy
