You can format text in group rows via the GridView.CustomDrawGroupRow event. To supply the new text for group rows, cast the event’s e.Info object to the GridGroupRowInfo object and then set the GridGroupRowInfo.GroupText property to the required value.

The HTML Text Formatting topic covers HTML tags you can use to format text.

Another way to format text in group rows is to use the GridView.GroupFormat property.


The following example shows how to use HTML tags to format text in group rows via the GridView.CustomDrawGroupRow event. In the example, when data is grouped by the Quantity column, the column’s group values are painted in different colors using the <color> tag.


New display text for group rows is supplied via the GroupText property of the event’s e.Info parameter.

using DevExpress.XtraGrid.Views.Base;
using DevExpress.XtraGrid.Views.Grid;
using DevExpress.XtraGrid.Views.Grid.ViewInfo;

gridView1.OptionsView.AllowHtmlDrawGroups = true;

private void gridView1_CustomDrawGroupRow(object sender, RowObjectCustomDrawEventArgs e) {
    GridView view = sender as GridView;
    GridGroupRowInfo info = e.Info as GridGroupRowInfo;
    if (info.Column.Caption == "Quantity") {
        int quantity = Convert.ToInt32(view.GetGroupRowValue(e.RowHandle, info.Column));
        string colorName = getColorName(quantity);
        info.GroupText = info.Column.Caption + ": <color=" + colorName + ">" + info.GroupValueText + "</color> ";
        info.GroupText += "<color=LightSteelBlue>" + view.GetGroupSummaryText(e.RowHandle) + "</color> ";

string getColorName(int value) {
    if (value < 20) return "MediumOrchid";
    if (value >= 80) return "OrangeRed";
    return "Blue";
