Debug the code and find the row counts of the datatable. then you will find the answer.

Please avoid putting the words like urgent. Its urgent for you not for us. Your post may get down votes just because of that.

Solution 1

i think you are getting this exception at third line.
Add before this

if(dspc.Tables[0].Rows.Count>0)
{
Label4.Text = dspc.Tables[0].Rows[0]["product_name"].ToString().Trim();
}
else
{
//return from code
//or dont handle that dataset in this part
}
