We can use the Network tool in F12 developer tools (Internet Explorer browser) to analyze why the page loads very slow. We can easily find which requests that takes time. Is it the data retrieval or other client process?

There are two types of event: events; and recurring events. Please try to check the retrieved events in ISDataSource OnSelected server side event. You can try to use following snippet code to determine the amount of returned events.

protected void ISDataSource1_Selected(object sender, ISNet.WebUI.DataSource.ISDataSourceStatusEventArgs e)
{
    if (e.ReturnValue.ToString()=="RecurringEvents")
    {
        WebScheduler_PersonalTrainee.RecurringEventsDataTable receventdt =
            e.ReturnValue as WebScheduler_PersonalTrainee.RecurringEventsDataTable;
        int RecurringEventsCount = receventdt.Count;
    }

    if (e.ReturnValue.ToString() == "Events")
    {
        WebScheduler_PersonalTrainee.EventsDataTable eventdt =
            e.ReturnValue as WebScheduler_PersonalTrainee.EventsDataTable;
        int RecurringEventsCount = eventdt.Count;
    }
}

Hope this help.

Glad to hear the good news.
