Hi Guyz,

SqlCommand cmd = new SqlCommand("select itemname from newitem where itemid = '" + DropDownList4.Text + "'", con);
SqlDataReader dr = cmd.ExecuteReader();
while (dr.Read() == true)
    string a = dr["itemname"].ToString();
    if (porder.Rows[i] != null)
        porder.Rows[i].Cells[0].Text = a.ToString();
        porder.Rows[i].Cells[2].Text = price();  
porder.DataSource = dr;
when i run the program i got error i row[i] index, Index was out of range. Must be non-negative and less than the size of the collection.

Isn't the error is obvious. Value of i is less than 0. Your code does not tells us how i is getting initialized. Same is the case of porder. If you are binding to pOrder why do you think porder.Rows should return you a valid collection prior to the binding.

Where are you stuck?

@ryanb31:He has clearly mentioned the error messege and the code snippet as well then there is no way to ask "Where are you stuck?".the error msg itself points out where he is stuck.

Try to add the below code before you do the while loop.
if (dr.HasRows)
while (dr.Read() == true)
