I have the following code:

    Protected Sub radEventScheduler1_FormCreating(ByVal sender As Object, ByVal e As Telerik.Web.UI.SchedulerFormCreatingEventArgs) Handles radEventScheduler1.FormCreating  

        e.Cancel = True 

        'Double clicked on appointment  

        If e.Mode = Telerik.Web.UI.FormMode.Insert Then 

            Response.Redirect("Page2.aspx", True)  

        ElseIf e.Mode = Telerik.Web.UI.FormMode.Edit Then 

            Response.Redirect("Page3.aspx, True)  

        Else 

            'Everything else - do nothing for now  

        End If 

    End Sub

What I want to do is to direct to different pages depending on whether the user is trying to add a new appointment or edit an existing one. I'm not sure if I used the correct radscheduler event for this (FormCreated). I do know that response.redirect doesnt work due to the fact that this is based on microsoft ajax. Is there a way to redirect to another page without using response.redirect?

Thanks

I have created a new page and copying most of the code from the old page seems to have done the trick and the new page is now working as intended (so far).

However, there is a bit of a snag. When creating / editing an appointment, I have the following code:

Protected Sub radEventScheduler1_FormCreating(ByVal sender As Object, ByVal e As Telerik.Web.UI.SchedulerFormCreatingEventArgs) Handles radEventScheduler1.FormCreating  

        'Double clicked on appointment  

        If e.Mode = Telerik.Web.UI.FormMode.Insert Or e.Mode = Telerik.Web.UI.FormMode.AdvancedInsert Then 

            Response.Redirect("Insert.aspx?key=0", True)  

        ElseIf e.Mode = Telerik.Web.UI.FormMode.Edit Or e.Mode = Telerik.Web.UI.FormMode.AdvancedEdit Then 

            Dim a As Integer = radEventScheduler1.Appointments.Count  

            Response.Redirect("eventdetails.aspx?key=" & e.Appointment.ID.ToString.Trim, True)  

        Else 

            'Everything else?  

            'lblMessage.Text = "Everything Else"  

            Dim a As Telerik.Web.UI.FormMode  

            a = e.Mode  

        End If 

        e.Cancel = True 

    End Sub

The redirecting on inserting an appointment works fine, but then I do the redirect for editing an appointment, I get the error "object reference not set to an intance of the object" for e.Appointment.ID.ToString.Trim.

Is there a way to get the ID that is passed to the radscheduler (i.e. the value in the DataKeyField property of the scheduler?

Again, thanks so much for your help and patience.

Hi Remrick,

This is bug in the preview refresh version, FormCreating does not always receive an appointment and that is why you receive the null reference exception. As a workaround, attach to the FormCreated event instead. We will fix it for the official release.

There is the special case when dealing with recurrent appointments. When the user has chosen to create a recurrence exception you will still get a form in edit mode, but the appointment will have an empty ID (null in current development builds) and it will be in the "Exception" state. In essence, you are expected to show an edit form in this case, but perform an insert on submit.

I have tried putting the code in the FormCreatedEvent instead and found another problem. When I try to edit an existing or create a new appointment it returns with the error in the following line in the scriptresource.axd file:

},Hide:function(_9){  

var _a=document.getElementById(_9);  

var _b=(!this.IsSticky)?document.getElementById(this.get_element().id+_9):this.get_element();  

var _c=new Date();  

if(_b==null){  

return;  

}

The error occurs on the var_b line, saying "Microsoft JScript runtime error: 'this.get_element().id' is null or not an object"

I note that this error only occurs if the current viewtype is not the same as the starting viewtype.

For example, if I set Scheduler1.viewtype = SchedulerViewType.DayView in the code behind page at page load, then the error doesnt happen when I create a new appointment in day view, but when I click on week or month to change the viewtype, then create or edit an appointment, then the error occurs. If I set the viewtype to weekview in the page load, then creating or editing an appointment in weekview is fine, but the error occurs when I go to day or month view and try to create it there.

If I change the viewtype by clicking on month or day and go back to weekview (which was the starting view) then the error occurs as well so it might have something to do with changing the view type.

Hi Remrick,

I am sorry for the late response. We are busy putting the final touches to the Q2 release and it will be available soon. You can monitor this forum thread for the latest announcements regarding the release.

I did not manage to reproduce the problem with the preview refresh version. I am attaching my test project, so you can verify that we are doing the same thing.

Try the the same example with the official Q2 release, when it is available. If the problem persists, please send your test project to support@telerik.com and include "RadScheduler #97928" in the subject line, so we can debug it locally.

All the best,
