How to change Gridview's row color based on a specific cell value? Asp.net

I browsed through dozens of websites and posts now and I can't find anything "right".

All I want is to paint a row with a red color in my Datatable/GridView based on specific cell value.

Please help me out here :( . . . 

for (int i = 0; i < TheFinalTable.Rows.Count; i++)
        {
            TheLevel = myUsers[i, 0];

            if (TheLevel == "2" && TheFinalTable.Rows[i][4].ToString() == myUsers[i, 1])
            {
                Gridview1.Rows[i].ForeColor = System.Drawing.Color.LightGreen;
            }
            if (TheLevel == "3" && TheFinalTable.Rows[i][4].ToString() == myUsers[i, 1])
            {
                Gridview1.Rows[i].ForeColor = System.Drawing.Color.Red;

            }
        }

"MyUsers" is a string array that contains The level and the ID.

            Level  |  id

       1  |   2       64


       2  |   3       23

"TheFinalTable" contains The following in this order: Mail, Name, Lastname, phone, ID, Rent, LastLog.

Just noticed it also says "Index was out of range" when it comes to the second if (which it is true).

The main question is this:

How to set different color to a specific row based on the row's one cell value or just by the row number?

Hope to hear from you guys soon.

Take care.

Subscribe to the RowDataBound event of the grid in your page's load method:

this.GridView1.RowDataBound += GridView1_RowDataBound;

Whenever the row is bound to the data, it will call your handler. Here is the event handler where you will do the changing of the background color:

private void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
   //make sure it is not the header row
   if(e.Row.RowType == DataControlRowType.DataRow)
   {
      // whatever your condition
      if(e.Row.Cells[0].Text == "Whatever")
      {
         e.Row.BackColor = Drawing.Color.Red // This will make row back color red
      }
   }
}
