Multiple Resource Values for Recurrence

[Alan Wang]

HI,

I tried Implementing A Provider That Supports Multi-valued Resources. It works fine for appointment without recurrence. When I switch from day view to week view it will show following message if  there is an appointment with recurrence.

Error: Sys.WebForms.PageRequestManagerServerErrorException: Failed to load viewstate.  The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request.  For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.

By the way, I tried to create a appointment with recurrence on your demo site using following link. It also throws exception:

Please let me know how to fix this

Just wondering if anyone from Telerik look into this bug. I tried myself for last two days and still no luck. I don't even know where throw the exceptions. This is very important to me. Please let me know if anyone figure out what wrong with it.

Thanks in advanced

Hi Alan,

I tested the case with the attached sample, but I was not able to replicate the problem. Could you please examine the demo and let me know what is different with your implementation?

Hi Peter,

Thanks for your reply.

I finally figure out what cause the problem. Here is my Scenario. In my scheduler, I have Appointment Template as following:

<AppointmentTemplate>

         <asp:HyperLink ID="lnkCase" runat="server" ImageUrl="~/Images/ViewCase_16.jpeg"></asp:HyperLink>

         <%# Eval("Subject")%>
</AppointmentTemplate>

Then I have event on appointment created find the hyperlink, enable/disable the hyperlink based on resources value, following is the code for AppointmentCreated event:

protected void schedulerAppt_AppointmentCreated(object sender, AppointmentCreatedEventArgs e) {       


        HyperLink lnkCase = (HyperLink)e.Container.FindControl("lnkCase");

        if (e.Appointment.Resources.GetResourceByType("Case").Key.ToString().CompareTo("0") == 0 ||

            e.Appointment.Resources.GetResourceByType("Case").Key.ToString().CompareTo("") == 0) {

            lnkCase.Visible = false;

        } else {

            lnkCase.Target = "_blank";

            lnkCase.NavigateUrl = "~/Case/Case.aspx?id=" + e.Appointment.Resources.GetResourceByType("Case").Key.ToString();

        }

}

If I take appointmentcreated event out, everything works fine.

Please help me, I need the hyperlink inside the appointment.

Thanks again
Alan
