RadScheduler Month View and Groupping Error

Hello Telerik Team,

I'm using your scheduler, and found a problem when adding an appointment to the scheduler using context menu.
I was able to reproduce the same problem in your online example: http://demos.telerik.com/aspnet-ajax/scheduler/examples/contextmenu/defaultcs.aspx.
To debug the problem, please set the scheduler to "Month View" and "Group by Calendar", next select 2 or 3 days using dragging on the timeslot and click in context option "New Appointment", in your example I'm redirected to this page "http://demos.telerik.com/ErrorPageResources/error.aspx?aspxerrorpath=/aspnet-ajax/scheduler/examples/contextmenu/defaultcs.aspx", I'm my code I get the error:
Resource index out of range: 6
at Telerik.Web.UI.Scheduler.Views.Month.GroupedByResource.Model.GetSlotByIndex(String index)
 at Telerik.Web.UI.Scheduler.Views.SchedulerModel.ProcessPostBackCommand(SchedulerPostBackEvent postBack)
 at Telerik.Web.UI.Scheduler.Views.SchedulerModel.<GetTimeSlotContextMenuCommands>b__1(ISchedulerModel ActiveModel, SchedulerPostBackEvent postBack)
 at Telerik.Web.UI.RadScheduler.ProcessTimeSlotContextMenuItemCommand(SchedulerPostBackEvent postBack)
 at Telerik.Web.UI.RadScheduler.ProcessPostBackCommand(SchedulerPostBackEvent postBack)
 at Telerik.Web.UI.RadScheduler.RaisePostBackEvent(String eventArgument)
 at Telerik.Web.UI.RadScheduler.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument)
.......

Is this a bug, or something I'm doing wrong?

Thanks for the fast reply.

This scheduler is running as a client web part (provider hosted app) in a Sharepoint.

OnClientClose in RadWindowManager vs RadWindow?

After spending 2 days trying to refresh the parent page when the rad window is closed. I was finally able to get somewhere. If I set the OnClientClose in the RadWindowManager my javascript function fires if I set it in the RadWindow it does not fire. Is this intended? What is the point of the OnClientClose in the RadWindow?

[Solved] Tabstrip example not working for me

I am trying to use the logic from the demo project listed here (http://demos.telerik.com/aspnet-ajax/tabstrip/examples/multipage/dynamic-pageview-creation/defaultvb.aspx), but It's not working as expected.

First, the onTabSelecting javascript is not finding previous pageViewId's and it keeps posting back.
Second, the code "e.Tab.PageView.Selected = True" in the TabClick event in the codebehind is throwing an error, "Object reference not set to an instance of an object." Upon inspection, e.Tab is showing it is a valid RadTab, but the PageView is Nothing.

I looked at everything, and it all looks correct. I have some logic to dynamically create the tabs and load the ascx into pageviews based upon a saved path in the database. The default.aspx uses a nested master, with the AjaxManager in the child master. It's setup like this:

Site.Master ---> Child.Master ---> Default.aspx

Here is the Default.aspx page.

<%@ Page Title="Home Page" Language="VB" MasterPageFile="~/Child.Master" AutoEventWireup="true" CodeBehind="Default.aspx.vb" Inherits="MainApp._Default" %>

Tooltip

Hi telerik-Support

I add all series manually via code-behind. The values for x-axis are dates and for y-axis are ints.
After render to the client the tool-tip shows the milliseconds of the date. You can see it on the attached file.

On code-behind I configure the series item like this:

...

lineSeries.LabelsAppearance.DataFormatString = "{1}";

lineSeries.TooltipsAppearance.DataFormatString = "{1} {0:d}";

...

How can I archive that on client side the date would be shown and not the milliseconds.

Thanks,
Christian

Download file from ajaxified control (download dialog not appearing)

I have several controls which were ajaxified using RadAjaxManager and I'm now trying to download a PDF. I understand

the issues with not being able to use Response.WriteFile (callbacks don't work...full postbacks do). I found

the following link on your site about using the ResponseScripts collection to get around this issue, i.e.,

http://www.telerik.com/help/aspnet-ajax/ajax-download.html

RadAjaxManager1.ResponseScripts.Add(String.Format(@"window.location.href = ""{0}"";", "http://yoursite.com/Your_File"));

This works fine...but the file appears in the existing browser window...I do not get the file download dialog.

Is there a way to add something similar to the following "content-disposition" header (with the attachment attribute)...so the download

file dialog appears? I need the downloaded file to appear in a separate window.

Response.AppendHeader("content-disposition", "attachment; filename = " + Path.GetFileName(fileName));
