Hope you are having a Label in the cell then you can change the cell color

protected void gvCities_RowDataBound(object sender, GridViewRowEventArgs e)
    {
      // Checking if row type
      if (e.Row.RowType == DataControlRowType.DataRow)
      {
        // find the label control
        Label lblSalary = e.Row.FindControl(“lblSalary”) as Label;
   
        // read the value from the datasoure
        Double Salary= Convert.ToDouble(Convert.ToString(DataBinder.Eval(e.Row.DataItem, “Rate”)));
   
        if (Salary < 9000.00)
        {
          // get the cell where that label contains
          DataControlFieldCell d = lblPrice.Parent as DataControlFieldCell;
   
          // to change the backcolor
          d.BackColor = System.Drawing.Color.Blue;
   
          // to change the row color by setting
          e.Row.BackColor = System.Drawing.Color.Red;
   
          // to change the text color like this
          lblPrice.ForeColor = System.Drawing.Color.Green;
         }
      }
     }
Cheers

For that you have to implement GridView RowDataBound() Event.

protected void GridView1_DataBound(object sender, GridViewRowEventArgs e){

if (e.Row.RowType == DataControlRowType.DataRow)

{

Label lbl= (Label )e.FindControl("LabelSalary");

if (lbl!=null)

{

if(Convert.ToInt32(lbl.Text)>10000))
{
  e.Row.BackColor=  System.Drawing.Color.Red;
}
else
{
   e.Row.BackColor=  System.Drawing.Color.Green;
}
}

}


}

Try this code and let me know.

Hi,

To accomplish this, you simply need to add a function to the “RowDataBound” attribute of the GridView.

01 GridView1.RowDataBound += new GridViewRowEventHandler (GridView1_RowDataBound);
02  
03  void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
04  {
05    if (e.Row.RowType == DataControlRowType.DataRow)
06    {
07      int salary=(int)DataBinder.Eval(e.Row.DataItem,e.Row.Cells[2].Text);
08      // e.Row.Cells[2] references the cell value you want to use
09      if (value < 100)
10      {
11        e.Row.Cells[2].BackColor = Color.FromName("#c6efce");
12      }
13      if ((salary>= 1000) && (salary< 5000))
14      {
15        e.Row.Cells[2].BackColor = Color.FromName("#ffeb9c");
16      }
17      if (salary>= 5000)
18      {
19        e.Row.Cells[2].BackColor = Color.FromName("#ffc7ce");
20      }
21    }
22  }

Try this way: 

void bind()
{
  foreach (GridViewRow r in GridView1.Rows)
  {
    //find id of lable based on visiblity of imagebutton
    Label lblCountry = (Label)r.FindControl("lblCountry");
    if (lblCountry.Text == "USA")
    {
      r.BackColor = System.Drawing.Color.Green;
    }     
  }
 }

foreach (GridViewRow row in grdv.Rows)
         {
Decimal Salary= Convert.ToDecimal(row.Cells["Give Index of Salary column"].Text.Trim());
        if(Salary>10000)
        {
          row.BackColor = Color.Red;
        }
         }
