[Solved] JSON Serialization?

[Jeff]

I am trying to implement the WCF sample into a web application project. I am using the exact XML provider, WCF service, and XML data file in your example (http://demos.telerik.com/aspnet-ajax/scheduler/examples/wcf/defaultcs.aspx).

Can someone help me with the source of this error? It seems to be a JSON issue.

When I set ResourcePopulationMode="ClientSide", I get a javascript error stating "Line: 5568 Error: 'undefined' is null or not an object."

When I set ResourcePopulationMode="ServerSide", I get a server error stating "Operation is not valid due to the current state of the object. " This is the last part of the stack trace:

System.Web.Script.Serialization.ObjectConverter.ConvertDictionaryToObject(IDictionary`2 dictionary, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject) +546658 System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeInternal(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject) +71 System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeMain(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject) +147 System.Web.Script.Serialization.ObjectConverter.ConvertObjectToType(Object o, Type type, JavaScriptSerializer serializer) +21 System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeInternal(Int32 depth) +181 System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeList(Int32 depth) +119 System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeInternal(Int32 depth) +210 System.Web.Script.Serialization.JavaScriptObjectDeserializer.BasicDeserialize(String input, Int32 depthLimit, JavaScriptSerializer serializer) +51 System.Web.Script.Serialization.JavaScriptSerializer.Deserialize(JavaScriptSerializer serializer, String input, Type type, Int32 depthLimit) +37 System.Web.Script.Serialization.JavaScriptSerializer.Deserialize(String input) +70 Telerik.Web.UI.Scheduling.ResourceDataSerializer.Deserialize(String json) +111 Telerik.Web.UI.SchedulerWebServiceClient.GetResources() +586 Telerik.Web.UI.RadScheduler.BindResourcesFromWebService() +95 Telerik.Web.UI.RadScheduler.PerformSelect() +123


I also noticed that if I remove the resources data from the XML file, no server error occurs and the client error changes to "Server method 'GetAppointments' failed."

Any help would be greatly appreciated.

Hi Jeff,

Please find attached a sample project that shows RadScheduler using a WCF service. It's basically a stripped down version of the WCF example.

The mentioned JSON error occurs when the server does not return valid JSON, usually because a server error caused ASP.NET to return an error page.
