DataGrid - Obtaining Cell Value Mehthods

Hi, There seems to be 3 ways (at least) to get to the value of a cell in a datagrid - For example one may use any of the following: GetColumnValueAtRow(r) DataGrid(r,c) DataGrid.DataSource.Rows(r)(c) 'Assuming the source is a datatable. Does any one know what is the difference between the above? Why should you use on over the other? Thanks. EKareem
