GridView

I think you should have done these selected column from different tables in query to come up with a signle table and view in page.

Ex:

        SQL Query

        SELECT          a.Col1, b.Col2, c.Col1, d.Col5
        FROM           Table1 a
        INNER JOIN    Table2 b
        ON         a.ID = b.ID
        INNER JOIN    Table3 c
        ON         a.ID = c.ID
        INNER JOIN    Table4 c
        ON         a.ID = d.ID

the result of this query is a single table with columns from different tables that conforms to the "JOIN CONDITION". This result can now be viewed in a datagrid
