lengthRuleCondition.Condition = FormatCondition.GreaterOrEqual;
lengthRuleCondition.Value1 = 25;
lengthRuleCondition.Appearance.BackColor = Color.MediumSeaGreen;
lengthRuleCondition.Appearance.Options.UseBackColor = true;
GridFormatRule lengthRule = new GridFormatRule() { Column = gridView.Columns["Length"], Rule = lengthRuleCondition };
gridView.FormatRules.Add(lengthRule);
gridView.RowCellStyle += (s, e) => {
GridView view = s as GridView;
if (view.IsRowSelected(e.RowHandle) &&
e.Column.FieldName == "Length" &&
lengthRule.IsFit(e.CellValue, view.GetDataSourceRowIndex(e.RowHandle)))
{
AppearanceObject ruleAppearance = (lengthRule.Rule as FormatConditionRuleAppearanceBase).Appearance;
e.Appearance.BackColor = ruleAppearance.BackColor;
