comparing the values in datagrid

Question

I am using C# / ASP.NET I've to compare the values of the columns in grid view to make the values in the first column unique. The values are stored in ViewState[CurrentTable] in code behind page. Suppose COL1 JAN FEB MAR APR Since the rows are editable the user might re-enter duplicate values but I've to prevent this too. How can I check the values in the column to prevent duplicate entry? Please suggest.
