How to: Format Display Text in Grid's Cells Depending on Values in Other Cells

  • 2 minutes to read

The following example shows how to dynamically customize the cell’s display text by handling the ColumnView.CustomColumnDisplayText event.

The grid View in the example contains the CurrencyType and Price columns. If the currency type is equal to 0, the price is displayed in dollars; if it is equal to 1, it is displayed in euros.


using DevExpress.XtraGrid.Views.Base;
using System.Globalization;

// The cultures used to format the values for the two different currencies.
CultureInfo ciUSA = new CultureInfo("en-US");
CultureInfo ciEUR = new CultureInfo("fr-FR", false);

private void gridView1_CustomColumnDisplayText(object sender, CustomColumnDisplayTextEventArgs e) {
    ColumnView view = sender as ColumnView;
    if (e.Column.FieldName == "Price" && e.ListSourceRowIndex != DevExpress.XtraGrid.GridControl.InvalidRowHandle)
        int currencyType = (int)view.GetListSourceRowCellValue(e.ListSourceRowIndex, "CurrencyType");
        decimal price = Convert.ToDecimal(e.Value);
        switch (currencyType)
            case 0: e.DisplayText = string.Format(ciUSA, "{0:c}", price); break;
            case 1: e.DisplayText = string.Format(ciEUR, "{0:c}", price); break;
