Cebik,

I tried dataGridView1.Rows.Add(iCount, Color.FromArgb(255)); but in the 2nd column; instead of displaying color for the value; it displayed Color[A=0; R=0 ; G=0; B=255]

Please advice whats wrong. Should I set some property to display color comwhere in the control?

Thanks,
Shan

What do you want to se?
Color name or background color of the cell in 2nd column?

If you want get name of color that will be HARD TO REACH because color.name gives you name only if you create color like this: Colo.Red or Color.White.
When you use Color.FromARGB(123231) or  Color.FromArgb(0, 0, 255); it will gives you something like this "ff0000ff".
If you want set background color of this cel into color from int then you must do this:

DataGridViewCell c1 = new DataGridViewTextBoxCell();
c1.Value = "";
 
DataGridViewCell c2 = new DataGridViewTextBoxCell();
c2.Style.BackColor = Color.FromArgb(232131);
c2.Value = "";
 
DataGridViewRow newRow = new DataGridViewRow();
newRow.Cells.AddRange(c1, c2);
 
dataGridView1.Rows.Add(newRow);
 
/* OR */
 
dataGridView1.Rows.Add(iCount, ""); 
dataGridView1[1, i-1].Style.BackColor = Color.FromArgb(16711935); //or "dataGridView1.Rows.Count-1" instead of "i-1"

offcourse
c1.Value = iCount;  //in your example

Cebik,

Yes 2nd column should be set to color specified. I made changes as per suggestion but it did not work. This is the code I have:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;



namespace ThresholdValues
{
    public partial class Form1 : Form
    {
       
        private int iCount;

        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click_1(object sender, EventArgs e)
        {
            int i;

            for (i = 1; i <= 10; i++)
            {
                iCount = iCount + 10;

                switch (i)
                {
                    case 1:
                         
                        dataGridView1.Rows.Add(iCount, "");
                        dataGridView1[1, i - 1].Style.BackColor = Color.FromArgb(255);
                        break;
                    case 2:
                        dataGridView1.Rows.Add(iCount, "");
                        dataGridView1[1, i - 1].Style.BackColor = Color.FromArgb(16711935);
                        break;
                    case 3:
                        dataGridView1.Rows.Add(iCount, "");
                        dataGridView1[1, i - 1].Style.BackColor = Color.FromArgb(16761087);
                        break;
                    case 4:
                        dataGridView1.Rows.Add(iCount, "");
                        dataGridView1[1, i - 1].Style.BackColor = Color.FromArgb(65280);                            
                        break;
                    case 5:
                        dataGridView1.Rows.Add(iCount, "");
                        dataGridView1[1, i - 1].Style.BackColor = Color.FromArgb(16776960);
                        break;
                }
            }

        }
       
    }
}

Please advice.

Thanks,
Shan

Cebik,
It displays colors only for 2 cells and those 2 colors are not set in the program. Not sure if I have to go this way or use some different control.

Thanks,
Shan
