You should not be doing this at all. Use a parameterized query.

Try the following :

SQL

...
sqlcmd.CommandText = "set identity_insert gl_Transaction On;";
sqlcmd.CommandText += "insert into Gl_Transaction(Compcode,Branchcode,Accountno,Acct_Name,SerialNo,Acct_Nirration,Value_Date,Voucher_No,Vchrtype,Dr_Amount,Cr_Amount,AddDate,UserId,pflag,InstrumentNo) values('" + dr.Cells[0].Value.ToString() + "','" + dr.Cells[1].Value.ToString() + "','" + dr.Cells[2].Value.ToString() + "','" + dr.Cells[3].Value.ToString() + "','" + dr.Cells[4].Value.ToString() + "','" + dr.Cells[5].Value.ToString() + "','" + dr.Cells[6].Value.ToString() + "','" + dr.Cells[7].Value.ToString() + "','" + dr.Cells[8].Value.ToString() + "','" + dr.Cells[9].Value.ToString() + "','" + dr.Cells[10].Value.ToString() + "','" + dr.Cells[11].Value.ToString() + "','" + dr.Cells[12].Value.ToString() + "','" + dr.Cells[13].Value.ToString() + "','" + dr.Cells[14].Value.ToString() + "')";
sqlcmd.CommandText += ";set identity_insert gl_Transaction Off";
...

[Edit]
If you need to use compound sql statements i.e. more than 1 then each one should end with a ';' semicolon.

Also in the case above you need to concat strings for the CommandText with += otherwise they get overwritten.
