Hello everybody !

I'm actually using Telerik Scheduler Q2 2009, and when I add some ressources allowing multiple values (AllowMultipleValues = "true"), I obtains the following error

[OleDbException (0x80040e21): Multiple-step OLE DB operation generated errors.Check each OLE DB status value, if available. No work was done.]
Telerik.Web.UI.Scheduling.DataSourceViewSchedulerProvider.OnDataSourceOperationComplete(Int32 count, Exception e) +16
System.Web.UI.DataSourceView.Insert(IDictionary values, DataSourceViewOperationCallback callback) +77
Telerik.Web.UI.Scheduling.DataSourceViewSchedulerProvider.Insert(RadScheduler owner, Appointment appointmentToInsert) +130
Telerik.Web.UI.Scheduling.AppointmentController.InsertAppointmentThroughProvider(Appointment appointment) +31
Telerik.Web.UI.RadScheduler.InsertAppointmentInline() +106
Telerik.Web.UI.RadScheduler.OnBubbleEvent(Object source, EventArgs args) +326
System.Web.UI.Control.RaiseBubbleEvent(Object source, EventArgs args) +37
System.Web.UI.WebControls.LinkButton.OnCommand(CommandEventArgs e) +118
System.Web.UI.WebControls.LinkButton.RaisePostBackEvent(String eventArgument) +135
System.Web.UI.WebControls.LinkButton.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) +10
System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +13
System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +175
System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1565

I'm using a Microsoft Access 2003 Database, is it due to Access ? or is it an error i've done ?

Thanks you very much for your help
Andrew

Hello Andrew,

Only custom providers can provide the support to allow multi-valued resources. Please, follow this help topic for step-by-step instructions on implementing a provider for multi-valued resources:
