Change GridView cell color

Question

Hello All,
My Page has a Gridview and a Servertimer control.
Gridview cells color should change if server time elapses.
Say for example, My ServerTime is 7.35 AM
If my Cell value is "7.31.00" means it elapsed when compared to ServerTime, so I need its color to change "Red".
else I would be in same Khaki color.
Any help would be much useful.
Thanks,
Vidhya.

I got the answer guys..

 private void button1_Click(object sender, EventArgs e)

        {

            OpenFileDialog ofImport = new OpenFileDialog();

            ofImport.Title = "Select file";

            ofImport.InitialDirectory = @"c:\";

            ofImport.FileName = openFileDialog1.FileName;

            ofImport.Filter = "Excel Sheet(*.xlsx)|*.xlsx|All Files(*.*)|*.*";

            ofImport.FilterIndex = 1;

            ofImport.RestoreDirectory = true;

            if (ofImport.ShowDialog() == DialogResult.OK)

            {

                string path = System.IO.Path.GetFullPath(ofImport.FileName);

                string query = "SELECT * FROM [Sheet1$]";

                OleDbConnection conn = new OleDbConnection();

                conn.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + ofImport.FileName + ";Extended Properties=" + "\"Excel 12.0 Xml;HDR=YES;IMEX=1\"";

                OleDbDataAdapter adapter = new OleDbDataAdapter(query, conn);

                DataSet dataSet = new DataSet();

                adapter.Fill(dataSet);

                dataGridView1.DataSource = dataSet.Tables[0];

            }

            else

            {

                ofImport.Dispose();

            }   

        }
