I am looking to access rows one after the other from sql database. I am unable to traverse through to the second row of the table. Below is the code sample. Please help.

C#

if (dr.HasRows)
                {
                    while (dr.Read())
                    //int i=0, j=0;
                    {

                Src_EpId = dr[0].ToString();
                //textBox13.Text = Src_EpId+"\n";

                Device_ID = dr[1].ToString();
                // textBox1.Text = Device_ID;
                Control_ID = dr[2].ToString();
                Control_Type = dr[3].ToString();
                Current_Value = dr[4].ToString();
                Message_State = dr[5].ToString();
                Change_Value = dr[6].ToString();
                Location = dr[7].ToString();
                Image_Url = dr[8].ToString(); // total columns = 9. rows = 5. How to access row2 column1, row2 column2 etc. individually?

while loop continues till there are records in datareader so no need to worry about the row2 column1 your code will access all the records.

Hi,

You can fill data to datatables first.After that you can access rows and columns whichever you want.

C#

DataTable dt = new DataTable();
dr.Load(dt);
foreach(DataRow dr in dt.Rows)
{
 dr["columnName"];
 // and other columns you can get
}
