Replacing SchedulerInfo in ResourcesPopulating not working

[David Bryant]

I using a web service to bind the scheduler and now trying to populate the resources.  I need to pass some additional info to the web service so I've created a class that implements ISchedulerInfo and have followed the instructions for passing additional info to the web service via a custom implementation of ISchedulerInfo.  I'm successful with the call to GetAppointments with additional parameters but I set the custom parameters in javascript. 

So, the web service settings show ResourcePopulationMode="ServerSide".  On the page...

    Protected Sub RadScheduler1_ResourcesPopulating(ByVal sender As Object, ByVal e As Telerik.Web.UI.ResourcesPopulatingEventArgs)
        Dim myInfo As New CustomSchedulerInfo
        myInfo.UserID = 1234
        e.SchedulerInfo = myInfo
    End Sub

Setting breakpoints shows ResourcePopulating firing before the web method call to GetResources. 

    <WebMethod()> _
    Public Function GetResources(ByVal schedulerInfo As CustomSchedulerInfo) As IEnumerable(Of ResourceData)
        Return Controller.GetResources(schedulerInfo)
    End Function

When I set a breakpoint in GetResources and evaluate schedulerInfo, schedulerInfo.UserID = 0 (default). 

Maybe I'm just missing some setting but it appears as though replacing e.SchedulerInfo is not working -- at least not in VB.

Any suggestions?

Hi David,

For your convenience, I have prepared a simple working demo which shows how to bind RadScheduler to a Web Service and how to filter appointments based on a selected resource. Here is the code with highlighted relevant sections:


MySchedulerInfo.cs

Copy Code

public class MySchedulerInfo : SchedulerInfo
{
    public string TeacherID { get; set; }
    public MySchedulerInfo(ISchedulerInfo baseInfo, string teacherID)
        : base(baseInfo)
    {
        TeacherID = teacherID;
    }
    public MySchedulerInfo()
    {

    }
}

SchedulerWebService.cs

Copy Code

[WebMethod]
    public IEnumerable<AppointmentData> GetAppointments(MySchedulerInfo schedulerInfo)
    {
        return Controller.GetAppointments(schedulerInfo);
    }

    [WebMethod]
    public IEnumerable<AppointmentData> InsertAppointment(MySchedulerInfo schedulerInfo, AppointmentData appointmentData)
    {
        return Controller.InsertAppointment(schedulerInfo, appointmentData);
    }

    [WebMethod]
    public IEnumerable<AppointmentData> UpdateAppointment(MySchedulerInfo schedulerInfo, AppointmentData appointmentData)
    {
        return Controller.UpdateAppointment(schedulerInfo, appointmentData);
    }

    [WebMethod]
    public IEnumerable<AppointmentData> CreateRecurrenceException(MySchedulerInfo schedulerInfo, AppointmentData recurrenceExceptionData)
    {
        return Controller.CreateRecurrenceException(schedulerInfo, recurrenceExceptionData);
    }

    [WebMethod]
    public IEnumerable<AppointmentData> RemoveRecurrenceExceptions(MySchedulerInfo schedulerInfo, AppointmentData masterAppointmentData)
    {
        return Controller.RemoveRecurrenceExceptions(schedulerInfo, masterAppointmentData);
    }

    [WebMethod]
    public IEnumerable<AppointmentData> DeleteAppointment(MySchedulerInfo schedulerInfo, AppointmentData appointmentData, bool deleteSeries)
    {
        return Controller.DeleteAppointment(schedulerInfo, appointmentData, deleteSeries);
    }

    [WebMethod]
    public IEnumerable<ResourceData> GetResources(MySchedulerInfo schedulerInfo)
    {
        return Controller.GetResources(schedulerInfo);
    }

RadSchedulerWebServiceCustomProvider.aspx

Copy Code

<script type="text/javascript">
       //Put your JavaScript code here.
       var teacherID = "all";
       function OnClientSelectedIndexChanged(sender, args) {
           teacherID = args.get_item().get_value();
           var scheduler = $find('<%=RadScheduler1.ClientID %>');
           scheduler.rebind();
       }
       function OnClientAppointmentsPopulating(sender, eventArgs) {
           eventArgs.get_schedulerInfo().TeacherID = teacherID;
       }
   </script>
   <p>
       Filter appointments by teacher (resource):
   </p>
   <p>
       <telerik:RadComboBox ID="RadComboBox1" runat="server" OnClientSelectedIndexChanged="OnClientSelectedIndexChanged">
           <Items>
               <telerik:RadComboBoxItem Text="All" Value="all" />
               <telerik:RadComboBoxItem Text="Teacher 1" Value="1" />
               <telerik:RadComboBoxItem Text="Teacher 2" Value="2" />
           </Items>
       </telerik:RadComboBox>
   </p>
   <telerik:RadScheduler ID="RadScheduler1" runat="server" OnClientAppointmentsPopulating="OnClientAppointmentsPopulating"
       AppointmentStyleMode="Default" SelectedView="WeekView" SelectedDate="2011-01-21" Width="600px">
       <WebServiceSettings Path="SchedulerWebService.asmx" ResourcePopulationMode="ServerSide" />
       <ResourceStyles>
           <telerik:ResourceStyleMapping Type="Teacher" Key="1" BackColor="Orange" />
           <telerik:ResourceStyleMapping Type="Teacher" Key="2" BackColor="Aqua" />
       </ResourceStyles>
   </telerik:RadScheduler>

MyDbSchedulerProvider.cs

Copy Code

public override IEnumerable<Appointment> GetAppointments(ISchedulerInfo shedulerInfo)
    {
        var myInfo = shedulerInfo as MySchedulerInfo;
        string teacherID = myInfo.TeacherID;

        List<Appointment> appointments = new List<Appointment>();

        using (DbConnection conn = OpenConnection())
        {
            DbCommand cmd = DbFactory.CreateCommand();
            cmd.Connection = conn;
            cmd.CommandText = "SELECT [ClassID], [Subject], [Start], [End], [RecurrenceRule], [RecurrenceParentId], [Reminder] FROM [DbProvider_Classes]";

            if (teacherID != "all")
                cmd.CommandText += "WHERE TeacherID = " + teacherID;

Peruse it at leisure and don't hesitate to contact us if you need further guidance. We will be glad to help.
