Example

The following example illustrates how to use the IsGroupSummary property.

Web Forms approach:

C#

protected void ASPxGridView1_SummaryDisplayText(object sender, DevExpress.Web.ASPxGridViewSummaryDisplayTextEventArgs e) {
    if (e.IsGroupSummary) {
        if (e.Item.FieldName == "UnitsOnOrder") {
            var val = TimeSpan.FromSeconds((int)e.Value);
            e.Text = string.Format("{0:c}", val);
        }
    }
}

VB.NET

Protected Sub ASPxGridView1_SummaryDisplayText(ByVal sender As Object, ByVal e As DevExpress.Web.ASPxGridViewSummaryDisplayTextEventArgs)
    If e.IsGroupSummary Then
        If e.Item.FieldName = "UnitsOnOrder" Then
            Dim val = TimeSpan.FromSeconds(CInt(Math.Truncate(e.Value)))
            e.Text = String.Format("{0:c}", val)
        End If
    End If
End Sub

MVC approach:

Razor

var grid = Html.DevExpress().GridView(settings =>
{
    settings.Name = "GridView";
    settings.KeyFieldName = "ID";
    ...
    settings.GroupSummary.Add(DevExpress.Data.SummaryItemType.Count, "TestField").ShowInGroupFooterColumn = "TestField";
    settings.GroupSummary.Add(DevExpress.Data.SummaryItemType.Sum, "NumberField").ShowInGroupFooterColumn = "NumberField";
    settings.SummaryDisplayText = (s, e) => {
        if (e.IsGroupSummary)
            if (e.Item.FieldName == "TestField")
                e.Text = "TestText";
    };
});
}
...
