解决方案

< blockquote>使用gridview的rowdatabound事件，你可以为所需的单元格或行提供颜色

  void  radGridView1_CellPaint（ object  sender，Telerik.WinControls.UI.GridViewCellPaintEventArgs e）
 {
 GridDataCellElement dataCell = e.Cell  as  GridDataCellElement; 
 
  if （dataCell！=  null && dataCell.ColumnInfo。名称==   UnitPrice）
 {
  double   value  = Convert.ToDouble（dataCell.Value）; 
  if （ value  ==  0 ）
 {
  return ; 
} 
 
画笔笔刷= 值 <   20 ？ Brushes.Red：Brushes.Green; 
 Size cellSize = e.Cell.Size; 
 
 使用（Font font =  new 字体（  Segoe UI， 17 ））
 {
 e.Graphics.DrawString（  *，font，brush，Point.Empty）; 
} 
} 
}

解决方案

use rowdatabound event of gridview and u can give colours to required cells or rows

void radGridView1_CellPaint(object sender, Telerik.WinControls.UI.GridViewCellPaintEventArgs e)
{
    GridDataCellElement dataCell = e.Cell as GridDataCellElement;

    if (dataCell != null && dataCell.ColumnInfo.Name == "UnitPrice")
    {
        double value = Convert.ToDouble(dataCell.Value);
        if (value == 0)
        {
            return;
        }

        Brush brush = value < 20 ? Brushes.Red : Brushes.Green;
        Size cellSize = e.Cell.Size;

        using (Font font = new Font("Segoe UI", 17))
        {
            e.Graphics.DrawString("*", font, brush, Point.Empty);
        }
    }
}
