Hi everybody,
I am using the RadGridScheduler Component to manage Activities by moving, editing or deleting them. In order to display a detailed view of the activity, a details window is opened using the RadWindowManager.
On this details view there is a button to delete the current activity. When I do this, the window gets closed and a javascript callback method is called from the scheduler’s aspx site to refresh the current content.
However, after the activity has been deleted within the RadScheduler’s AppointmentDelete event and the aspx site gets load again, the following Exception has been thrown:
[NullReferenceException: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.]
Telerik.Web.UI.SchedulerPostBackEvent.DeserializeFromJSON(String json) +85
Telerik.Web.UI.RadScheduler.RaisePostBackEvent(String eventArgument) +67
Telerik.Web.UI.RadScheduler.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) +7
System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +11
System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +177
System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1746
Has anybody an idea, what went wrong?
Thanks in advance.
