DevExpress GridView conditional coloring with the query you want to do after filling.

The following code loops but affects all rows, where the problem might be.

for (int i = 0; i < gridView1.RowCount; i++)
            {
              int val = Convert.ToInt32(gridView1.GetRowCellValue(i, "MEMBERID"));
           if (val==2)
                 {
                     gridView1.Columns["MEMBERID"].AppearanceCell.BackColor = Color.Red;
                 }
                 else
                 {
                     gridView1.Columns["MEMBERID"].AppearanceCell.BackColor = Color.RoyalBlue;

                 }

public Form1()
  {
      InitializeComponent();
  }

  private void Form1_Load(object sender, EventArgs e)
  {
      IPAddress[] localip = Dns.GetHostAddresses(Dns.GetHostName());
      foreach (IPAddress address in localip)
      {
          if (address.AddressFamily == AddressFamily.InterNetwork)
          {
              textBox1.Text = address.ToString();
              textBox2.Text = "8888";
          }
      }
  }

  private void button1_Click(object sender, EventArgs e)
  {
      TcpListener listenner = new TcpListener(IPAddress.Any, int.Parse(textBox2.Text));
      listenner.Start();
      tcpclient = listenner.AcceptTcpClient();

  }
