Calling RadScheduler1.Rebind() duplicates resources with ServerSide ResourcePopulationMode

[Dev]

We have a RadScheduler using a web service binding with ResourcePopulationMode="ServerSide".  The GetResources method is as per the documentation:

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

If we call RadScheduler1.Rebind() in the code behind then GetResources is called but the resources are added to the RadScheduler rather than replacing them, with the result that duplicate resources appear.

Is this the expected behaviour?  Are we supposed to be rebinding the scheduler differently?

Hello Rob,

 
Thank you for contacting Telerik support.

Yes this is am expected behavior when RadScheduler is bound to Web Service binding  that is caused by the specific way the resources are loaded from the server side in such scenarios. That is why in such cases we recommend rebinding RadScheduler as in the code below:

protected void RadButton1_Click(object sender, EventArgs e)
      {
          RadScheduler1.Resources.Clear();
          RadScheduler1.Rebind();
      }

Hope this will explain the issue. If you have further questions please don't hesitate to contact us again.
