How to: Apply Conditional Formatting to Grid Cells using the Bar Color Ranges Format Condition

  • 2 min to read

The Bar Color Ranges condition (FormatConditionColorRangeBar) allows you to visualize numeric values using bars whose colors are contained in the specified color set.

This example shows how to display colored bars within Grid cells. Use the Update Formatting button to change the number of ranges, specify new range boundaries and customize colors corresponding to existing ranges.

using DevExpress.DashboardCommon;

namespace Grid_IconRangeCondition {
    public partial class Form1 : DevExpress.XtraEditors.XtraForm {
        public Form1() {
            Dashboard dashboard = new Dashboard(); dashboard.LoadFromXml(@"..\..\Data\Dashboard.xml");
            dashboardViewer1.Dashboard = dashboard;
            GridDashboardItem grid = (GridDashboardItem)dashboard.Items["gridDashboardItem1"];
            GridMeasureColumn extendedPrice = (GridMeasureColumn)grid.Columns[1];

            GridItemFormatRule rangeRule = new GridItemFormatRule(extendedPrice);
            FormatConditionColorRangeBar rangeBarCondition =
                new FormatConditionColorRangeBar(FormatConditionRangeSetPredefinedType.ColorsRedGreenBlue);
            rangeBarCondition.BarOptions.ShowBarOnly = true;
            rangeRule.Condition = rangeBarCondition;


        private void button1_Click(object sender, System.EventArgs e) {
            GridDashboardItem grid = 
            GridItemFormatRule rangeRule = grid.FormatRules[0];
            FormatConditionColorRangeBar rangeBarCondition = (FormatConditionColorRangeBar)rangeRule.Condition;
            RangeInfo range3 = rangeBarCondition.RangeSet[2];
            range3.Value = 50;
            range3.StyleSettings =
                new BarStyleSettings(FormatConditionAppearanceType.GradientGreen);

            RangeInfo range4 = new RangeInfo();
            range4.Value = 75;
            range4.StyleSettings =
                new BarStyleSettings(FormatConditionAppearanceType.GradientBlue);

            rangeRule.Condition = rangeBarCondition;
