How to: Apply Conditional Formatting to Data Cells

  • 3 minutes to read

This example shows how to add format conditions to WPF Pivot Grid Control.

  • The Data Bar conditional formatting is applied to the 'Extended Price' measure and intersection of the 'Sales Person' and 'Quarter' fields. This condition formats data cells with a predefined orange gradient data bar.
  • The Top Bottom Rule conditional formatting is applied to the 'Quantity' measure and intersection of the 'Sales Person' and 'Quarter' fields. This condition formats data cells whose values are above average with green text and light green fill.
  • The Icon Set conditional formatting is applied to the 'Extended Price' measure and intersection of the 'Sales Person' and 'Year' fields. This condition displays a specific icon in a cell according to the range to which this cell value belongs.

The image below shows the result.

Pivot Grid Conditional Formatting example

using System.Windows;
using System;
using DevExpress.Xpf.PivotGrid;

namespace WpfPivotGridConditionalFormatting
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();

            FilterFieldValues(fieldYear, new int[]{2016}, FieldFilterType.Included);

            // Creates a new DataBarFormatCondition instance.
            DataBarFormatCondition formatRulesDataBar = new DataBarFormatCondition();

            // Adds this instance to the FormatConditionCollection.
            pivotGridControl1.AddFormatCondition(formatRulesDataBar);

            // Specifies a column field.
            formatRulesDataBar.ColumnName = "fieldQuarter";

            // Specifies a row field.
            formatRulesDataBar.RowName = "fieldSalesPerson";

            // Specifies a data field.
            formatRulesDataBar.MeasureName = "fieldExtendedPrice";

            // Applies the condition to intersection of row and column fields.
            formatRulesDataBar.ApplyToSpecificLevel = true;

            // Sets the predefined format.
            formatRulesDataBar.PredefinedFormatName = "OrangeGradientDataBar";


        }

        private void FilterFieldValues(PivotGridField field, int[] filterValues, 
            FieldFilterType filterType)
        {
            pivotGridControl1.BeginUpdate();
            try
            {
                field.FilterValues.Clear(); 
                foreach (object filterValue in filterValues)
                    field.FilterValues.Add(filterValue);
            }
            finally
            {
                field.FilterValues.FilterType = filterType;
                pivotGridControl1.EndUpdate();
            }
        }
