we are exposing Devexpress ReportDesigner to user for creating structure
but issue is that if user take time to design report structure session get expired....

so i am looking for any call back event to be fired on each activity to keep session alive

@Html.DevExpress().ReportDesigner(settings =>
{
    settings.Name = "reportDesigner";
    object newReportUrl = new { Controller = "Canvas", Action = "AddNewCanvas", name = Model.ReportName };
    object existReportUrl = new { Controller = "Canvas", Action = "UpdateCanvas", id = Model.RHID };
    settings.SaveCallbackRouteValues = Convert.ToInt64(Model.RHID) != 0 ? existReportUrl : newReportUrl;
    settings.Height = System.Web.UI.WebControls.Unit.Percentage(100);
    settings.ControlStyle.CssClass = "fullscreen";
    if (Model.dt != null)
    {
        settings.DataSources.Add("Canvas", Model.dt);
    }
//setting.callback something for each activity 
    settings.CustomJSProperties = (_, e) => e.Properties["cpIndexUrl"] = Url.Action("Index", "Home");
}).Bind(Model.report).GetHtml()
