How to: Display Summaries

This example shows how to create data summaries in code. To display group summaries, enable the TreeListSettings.ShowGroupFooter option. To show total summaries, turn on the TreeListSettings.ShowFooter option. The image below shows the result:


using DevExpress.Web.ASPxTreeList;

protected void Page_Load(object sender, EventArgs e) {
    if (!IsPostBack) {
        TreeListSummaryItem siBudget = new TreeListSummaryItem();
        siBudget.FieldName = "BUDGET";
        siBudget.ShowInColumn = "BUDGET";
        siBudget.SummaryType = DevExpress.Data.SummaryItemType.Min;
        siBudget.DisplayFormat = "{0:c2}";
