I have try to delete all property and quickly got another error:

Error Creating Control - RadScheduler1'End' could not be set on property 'DataEndField'.

I alse have to try assign properties on the fly, but I have got many client scripts errors.

Thank you very much.

Hey,

I have a very similar (in fact basically identical problem). With the AppointmentFactory="" in place, I get the [Cannot create an object of type 'Telerik.Web.UI.IAppointmentFactory'] error.

If I manually remove the property, as suggested (and even rebuilding+restarting VS 2008 before the next attempt), I get the following error [System.InvalidOperationException: The control with ID 'RadScheduler1' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.].

I was following the getting started document, here (the problem arises at step 20).

Any suggestions?

More information about script error:

I am including scheduler on thy fly with these properties:

<RadScheduler DataStartField="att_50134" DataEndField="att_50135" DataKeyField="n_id" DataSubjectField="n_code_name" CustomAttributeNames="n_nug_typ_id,att_50132_key" HoursPanelTimeFormat="htt" Skin="Office2007" StartInFullTime="true" OverflowBehavior="Expand" SelectedView="MonthView" AllowEdit="false" AllowDelete="false" AllowInsert="false" Width="100%" Height="100%">
</RadScheduler>

My page has a <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >

Sometimes the scheduler window contains only table without days numbers (in moth view). When the mouse cursor is moving over the table, the appointments are visible suddenly. Really strange. I am using IE 8.0.

Thank you.

Okay, trying the updated version. Just want to first confirm that I simply copied over the files in the internal build download, over the installed version, as that seemed to be the correct approach.

With this setup, I run into the problem that the control is no longer properly added to the form.

I get:

    
            Error Creating Control - RadScheduler1 
        
            Failed to create designer 'Telerik.Web.UI.RadScheduler, Telerik.Web.UI, Version=2009.1.604.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4'

Since it seems to be relevant in this case, this is on
VS 2008, Version 9.0.30729.1 SP
With .NET 3.5 SP1

Cheers for the help so far.

Cheers, gave that a shot, but it didn't appear to fix the issue. So I ended up adding an explicit reference to the dll files to the project to get around it. Just for reference, the project and GAC trees.

Still though, when running the program I hit the ScriptManager error:

    
            The control with ID 'RadScheduler1' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.

                        DataKeyField="ID" DataRecurrenceField="RecurrenceRule"

                        ValidationGroup="RadScheduler1"> 
        
                    </telerik:RadScheduler>

Thanks again on the help.

Hello Sergey,

Do you have a scriptmanager control in your page? Also please make sure you are using the right version of Telerik.Web.UI.dll in your project. If it is built for ASP.NET 2.0 you should use the 2.0 build of Telerik.Web.UI located in the bin folder of your installation. If you are using ASP.NET 3.5 you need the 3.5 build which can bound in the bin35 folder of the radcontrols installation.

Kind regards,
Albert
