Hello,

At the moment i have a scheduler inplemented in my application. I made it exactly as in the examples is described. The problem is at the moment, that when there are appointments on the overview, pointing to different timeslots is workign kinda laggy and slow. it takes a while before it lights up the timeslot of one hour where i have my mouse on it. I searched the Telerik forum, for performance problems and im already using the radscriptmanager as well the radstylesheetmanager.

My code is below:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="ucQuickPlan.ascx.cs"

Inherits="VEGAS_HPF.Hoofdmenu.Agenda.ucQuickPlan" %>

<%@ Register Src="AdvancedForm.ascx" TagName="AdvancedForm" TagPrefix="scheduler" %>

<style type="text/css">

.RadScheduler .rsAptSubject

{

text-align: left;

padding: 4px 0 1px;

margin: 0 0 3px;

font-size: 12px;

font-weight: bold;

color: #369;

height: 17px;

border-bottom: 1px solid #99DEFD;

width: 100%;

}

.RadScheduler .rsAdvancedEdit .RadColorPicker label

{

text-align: left;

display: block;

padding: 0;

}

</style>

<script type="text/javascript">

//<![CDATA[

// Dictionary containing the advanced template client object

// for a given RadScheduler instance (the control ID is used as key).

var schedulerTemplates = {};

function schedulerFormCreated(scheduler, eventArgs) {

// Create a client-side object only for the advanced templates

var mode = eventArgs.get_mode();

if (mode == Telerik.Web.UI.SchedulerFormMode.AdvancedInsert ||

mode == Telerik.Web.UI.SchedulerFormMode.AdvancedEdit) {

// Initialize the client-side object for the advanced form

var formElement = eventArgs.get_formElement();

var templateKey = scheduler.get_id() + "_" + mode;

var advancedTemplate = schedulerTemplates[templateKey];

if (!advancedTemplate) {

// Initialize the template for this RadScheduler instance

// and cache it in the schedulerTemplates dictionary

var schedulerElement = scheduler.get_element();

var isModal = scheduler.get_advancedFormSettings().modal;

advancedTemplate = new window.SchedulerAdvancedTemplate(schedulerElement, formElement, isModal);

advancedTemplate.initialize();

schedulerTemplates[templateKey] = advancedTemplate;

// Remove the template object from the dictionary on dispose.

scheduler.add_disposing(function() {

schedulerTemplates[templateKey] = null;

});

}

// Are we using Web Service data binding?

if (!scheduler.get_webServiceSettings().get_isEmpty()) {

// Populate the form with the appointment data

var apt = eventArgs.get_appointment();

var isInsert = mode == Telerik.Web.UI.SchedulerFormMode.AdvancedInsert;

advancedTemplate.populate(apt, isInsert);

}

//]]>

RadScheduler1.DataKeyField = "id";

RadScheduler1.DataStartField = "afspraakdatum";

RadScheduler1.DataEndField = "afspraakdatumEind";

RadScheduler1.DataSubjectField = "afspraakopmerkingen";

//RadScheduler1.GroupBy = "adviseur_id";

RadScheduler1.GroupingDirection = GroupingDirection.Horizontal;

RadScheduler1.DataSource = cls_VEGAS_HPF.getDataset("exec sp_getAgendaItems", "ConnWB");

RadScheduler1.ResourceTypes.Add(restype1);

DataTable dt_Kamers = cls_VEGAS_HPF.getDataTable("SELECT * FROM tblDLocatieKamer", "ConnHPF");

ResourceType restype2 = new ResourceType("Kamer");

restype2.DataSource = dt_Kamers;

restype2.KeyField = "intKamerID";

restype2.TextField = "strKamerNaam";

restype2.ForeignKeyField = "intKamerID";

RadScheduler1.ResourceTypes.Add(restype2);

RadScheduler1.GroupBy = "Adviseur";

}

protected void RadScheduler1_DataBound(object sender, EventArgs e)

{

//RadScheduler1.ResourceTypes.FindByName("User").AllowMultipleValues = true;

//RadScheduler1.ResourceTypes.FindByName("Room").AllowMultipleValues = false;

}

protected void RadScheduler1_AppointmentDataBound(object sender, SchedulerEventArgs e)

{

string colorAttribute = e.Appointment.Attributes["AppointmentColor"];

if (!string.IsNullOrEmpty(colorAttribute))

{

int colorValue;

if (int.TryParse(colorAttribute, out colorValue))

{

Color appointmentColor = Color.FromArgb(colorValue);

e.Appointment.BackColor = appointmentColor;

e.Appointment.BorderColor = Color.Black;

e.Appointment.BorderStyle = BorderStyle.Solid;

e.Appointment.BorderWidth = Unit.Pixel(1);

}

e.Appointment.ToolTip = e.Appointment.Subject + ": " + e.Appointment.Description;

}

Any help is much appriciated.

Hello Peter,

The link you gave me, might be true. However, it seems to me the problem is not exactly in the scheduler itself, but in the appointment. Because when i have appointments in my selected day, it starts working enormously slow. When there aren't appointments in the selected day view, it works acceptable fast. It has also nothing to do with how many appointments there are in the Scheduler, since when i have no appointments in the selected day view, there are appointments in the scheduler itself since i load ,during my test fase, all the appointments which i have in the table.

Still, a Telerik employee stated there that they would fix it, what is the status of that since i don't see it in the overview of upcoming fixes as well?

Regards,

Corné
