Hi,
Pls change your Query like this.

con.Open();
string sqlStr ="insert into clientwiseproductwise(productcategory,discounttype,scount,Dfactor)values ('" + productcategoryDataGridViewTextBoxColumn + "','" + discounttypeDataGridViewTextBoxColumn + "','" + DiscountValue + "','" + dfactorDataGridViewTextBoxColumn + "')"

SqlCommand cmd = new SqlCommand(sqlStr , con);

Now check the values of sqlStr ..

And run that values into Sqlserver...

Regards,
Saran
