How to disable the radscheduler when there's no data

I've a radscheduler reading it's data in from a provider (which connects to exchange). If there's no account to connect to, or a problem with the service, I want the scheduler to simply be disabled and not render.

So I thought this simple peice of logic would do the trick:

if (Service != null)

{

Calendar.DayStartTime = TimeSpan.Parse("05:00:00");

Calendar.DayEndTime = TimeSpan.Parse("23:00:00");

Calendar.Culture = System.Globalization.CultureInfo.CreateSpecificCulture("en-GB");

Calendar.WeekView.HeaderDateFormat = "d";

ScheduleProvider ExchangeScheduleProvider = new ScheduleProvider();

ExchangeScheduleProvider.ExchangeService = Service;

Calendar.Provider = ExchangeScheduleProvider;

}

else

{

Calendar.Enabled = false;

Calendar.Visible = false;

}

However, even though the scheduler shouldn't be enabled now in theory, it seems to ignore this and is desperate to try and databind. I get the following error:


            [ArgumentException: DataKeyField, DataSubjectField, DataStartField and DataEndField are required for databinding]
   Telerik.Web.UI.Scheduling.DataSourceViewSchedulerProvider.EnsureDataFieldsAreSet() +204

Nowhere in my code do I set a datasource or tell it to databind.
I don't want it to databind or do anything, how do I disable the control?

if the user change row, call the sql update
if the user press enter, call the sql update

<script type="text/javascript">

function RowClick(sender, eventArgs)

{

sender.get_masterTableView().editItem(eventArgs.get_itemIndexHierarchical());

}

function keyPressed(sender, args) {

if (args.get_keyCode() == 13) {

sender.get_masterTableView().updateItem($(el).parents("tr")[0]);

var e = args.get_domEvent().rawEvent;

e.returnValue = false;

e.cancelBubble = true;

if (e.stopPropagation) {

e.preventDefault();

e.stopPropagation();

Master/Content RadAjaxManager - IE Error

JavaScript on Content Page:

function onRequestStart(sender, args) {

currentLoadingPanel = $find("<%= RadAjaxLoadingPanel1.ClientID %>");

currentUpdatedControl = "<%= rightPanel.ClientID %>";

//show the loading panel over the updated control

currentLoadingPanel.show(currentUpdatedControl);

}

function onResponseEnd() {

//hide the loading panel and clean up the global variables

if (currentLoadingPanel != null)

currentLoadingPanel.hide(currentUpdatedControl);

currentUpdatedControl = null;

currentLoadingPanel = null;

}

function InitiateAsyncResults(argument) {

var m = $find("<%=RadAjaxManager.GetCurrent(Page).ClientID %>");

m.ajaxRequest(argument);

return false;

}

Page Load on Content Page

RadAjaxManager manager = RadAjaxManager.GetCurrent(Page);

manager.AjaxSettings.AddAjaxSetting(manager, rightPanel);

manager.ClientEvents.OnRequestStart = "onRequestStart";

manager.ClientEvents.OnResponseEnd = "onResponseEnd";

manager.AjaxRequest += new RadAjaxControl.AjaxRequestDelegate(manager_AjaxRequest);

Working great in Firefox, but is throwing an error in IE (error below). I've added alerts into the JavaScript, to make sure it's finding the RadAjaxManager and the other controls and it is. Again it's working fine in Firefox.

Need to add a letter 'W' in RadDatePicker

Hi all,

I have a page with RadDatePicker and RadGrid, etc.

Which all works fine without any issue.

Ok. While RadDatePicker is viewed, A column appears for Week Serial No without a heading.

Then it follows with S, M ,T, W, T, F and S. Many of the End Users are getting confused of it.

Need to insert a letter in the heading of Week Serial No.

Is there any option to Add or Insert.

Thank You.

Calling ContentTemplated RadWindow Open from CodeBehind

I have a situation that I need some answers for please. I am working with the RadWindow control using the Contenttemplate. When my RadGrid is in EditMode, and user makes a selection from a contained dropdownlist, I would like to PopUp the RadWindow at that point showing user adding options to help further filter data. When user clicks to close the Radwindow, I want to return to my EditMode RadGrid displaying the selected options in my RadGrid Textbox.

My question is, how do I get my radwindow(content template) to display from codebehind.

<telerik:RadWindow ID="UserListDialog" runat="server" Title="Editing record" Width="250" Height="536" KeepInScreenBounds="true" Modal="true" Behaviors="Minimize, Move, Resize, Maximize" Left="580" Top="-8" EnableShadow="true">

<ContentTemplate>

<asp:Panel ID="PnlUserRoleList">

<asp:CheckBoxList ID="UserRoleCheckBoxList" runat="server" Width="60%" />

<asp:Button ID="btnAddselected" Text="AddItems" runat="server" />

<asp:Button ID="btnCancel" Text="Cancel" runat="server" />

</asp:Panel>

</ContentTemplate>

</telerik:RadWindow>
