The image below shows the result:


using DevExpress.Web.ASPxTreeList;

protected void ASPxTreeListExporter1_RenderBrick(object sender,
DevExpress.Web.ASPxTreeList.Export.ASPxTreeListExportRenderBrickEventArgs e) {
    if (e.RowKind == TreeListRowKind.Data && e.Column != null &
        e.Column.FieldName == "Department") {
        if (Convert.ToInt32(ASPxTreeList1.FindNodeByKeyValue(e.NodeKey)["Budget"]) < 100000)
            e.BrickStyle.BackColor = System.Drawing.Color.Orange;
