I have made a dataTableAdapter and defined it as a source for my radGrid. Everything is fine, I am getting all columns from my table but have changed datetime format using DATEADD(dd, 0, DATEDIFF(dd, 0, DateTime)). Now i just need to sort all my records in descending order (thats it latest ones first). So I have tried sorting it in my query using Order By clause and through sortExpressions in radGrid as well. But its not working...please help me!
