Incorrect times (+1) displayed in scheduler

Hi, I'm struggling to get times to be consistent between the RadScheduler when retrieving data from Exchange via EWS. I only need to work in GMT timezone. I've set what I think are all necessary TimeZones to GMT, but when retrieving the data the appointments are shown +1 hour as compared to Outlook. Some example code to show what is happening is below. When adding a new appointment this seems to work OK and is consistent. When updating however, the e.ModifiedAppointment.Start date is an hour behind what I actually choose in the RadScheduler. Any help appreciated.

<telerik:RadScheduler TimeZoneID="GMT Standard Time" RenderMode="Lightweight" runat="server" ID="RadScheduler1" DayStartTime="07:00:00" Height="600px"
DayEndTime="20:00:00" OnAppointmentInsert="RadScheduler1_AppointmentInsert"
OnAppointmentUpdate="RadScheduler1_AppointmentUpdate" OnAppointmentDelete="RadScheduler1_AppointmentDelete"
DataKeyField="ID" DataSubjectField="Subject" DataStartField="Start" DataEndField="End" DataTimeZoneIdField="TimeZone" Skin="WebBlue"
RowHeight="28px" MinutesPerRow="30" FirstDayOfWeek="Monday" LastDayOfWeek="Friday" OverflowBehavior="Auto">
<AdvancedForm Modal="true"></AdvancedForm>
<TimelineView UserSelectable="false"></TimelineView>
<TimeSlotContextMenuSettings EnableDefault="true"></TimeSlotContextMenuSettings>
<AppointmentContextMenuSettings EnableDefault="true" ></AppointmentContextMenuSettings>
<Reminders Enabled="false"></Reminders>
</telerik:RadScheduler>

Public Function LoadAppointments() As List(Of RevAppointment)
Dim appointments As New List(Of RevAppointment)
Dim now = Date.Now
Dim startDate As Date = New Date(now.Year, now.Month, now.Day, 0, 0, 0)
Dim endDate As Date = startDate.AddDays(7)
Dim calendar As CalendarFolder = CalendarFolder.Bind(Me.ExService, WellKnownFolderName.Calendar, New PropertySet())
Dim cView As New CalendarView(startDate, endDate, 250)
cView.PropertySet = New PropertySet(AppointmentSchema.Subject, AppointmentSchema.Start, AppointmentSchema.End, AppointmentSchema.Id, AppointmentSchema.TimeZone, AppointmentSchema.StartTimeZone, AppointmentSchema.EndTimeZone)
Dim cAppointments As FindItemsResults(Of Microsoft.Exchange.WebServices.Data.Appointment) = calendar.FindAppointments(cView)
For Each cAppointment In cAppointments
Dim tz = TimeZoneInfo.GetSystemTimeZones().FirstOrDefault(Function(x) x.DisplayName = cAppointment.TimeZone)
Dim appointment As New RevAppointment
appointment._id = cAppointment.Id.ToString
appointment.Start = cAppointment.Start
appointment.End = cAppointment.End
appointment.Subject = cAppointment.Subject
appointment.TimeZone = tz.Id
appointments.Add(appointment)
Next
Return appointments
End Function

Protected Sub RadScheduler1_AppointmentUpdate(ByVal sender As Object, ByVal e As Telerik.Web.UI.AppointmentUpdateEventArgs)
Dim id As New ItemId(e.Appointment.ID)
Dim ps As New PropertySet(AppointmentSchema.Subject, AppointmentSchema.Start, AppointmentSchema.End, AppointmentSchema.Id, AppointmentSchema.TimeZone, AppointmentSchema.IsMeeting)
Dim updatedAppt As Appointment = Appointment.Bind(Me.ExService, id, ps)
updatedAppt.Subject = e.ModifiedAppointment.Subject
updatedAppt.Body = e.ModifiedAppointment.Description
updatedAppt.Start = e.ModifiedAppointment.Start

updatedAppt.Location = ""
updatedAppt.ReminderDueBy = DateAdd(DateInterval.Minute, -15, e.ModifiedAppointment.Start)

Dim mode As SendInvitationsOrCancellationsMode
If updatedAppt.IsMeeting Then

Else
mode = SendInvitationsOrCancellationsMode.SendToNone
End If

RadClientDataSource On Demand Paging

Is there an example of using On Demand Paging with a RadClientDataSource.

We have a RadClientDataSource that connects to a controller return json data. We pass the page index, and page size to the controller, and it returns the records for that page, as well as the total count that we assign to the virtualCount.

However, when we try to page, we get an "Out of stack space". We do not see another call to our parameter map function to get another page. How do we set this up?

Import excel with path to RadSpreadsheet

Hi, I'm trying to bind between an excel file and the RadSpreadsheet control using what I checked in your forums.
The code I use and does not work is:
Dim formatProvider As Telerik.Windows.Documents.Spreadsheet.FormatProviders.IWorkbookFormatProvider = New Telerik.Windows.Documents.Spreadsheet.FormatProviders.OpenXml.Xlsx.XlsxFormatProvider
Using input As Stream = New FileStream(filePath, FileMode.Open)
RadSpreadsheet1.Sheets.AddRange(Telerik.Web.Spreadsheet.Workbook.FromDocument(formatProvider.Import(input)).Sheets)
End Using

In the UI part
</div>
<telerik:RadSpreadsheet runat="server" ID="RadSpreadsheet1">
<div>

The version of the spreadsheet is 2016.2.421.40 and telerik web.UI 2016.2.504.40.
I'm trying to get this code working in chrome.

How to get all child nodes for a RadTreeView

Hi,

I am using a RadTreeView & the tree menu is data sourced. On the server side when I try to grab the nodes using

foreach (RadTreeNode node in RadTreeView1.Nodes)

This provides only the root nodes (the ones at the higher level). All of the nodes have quite few child node & subfolders (which again contain child nodes). How can I scroll thru all the nodes in the tree?

Thank you

[Solved] Failed to load viewstate

Hi.
I am not good at English.

I use RadTreeView for Ajax 2009 Q3.
I try to maintain a state of RadTreeView Nodes before creating a new folder via right-clicking menu.
The sorce code is the following.

    
            namespace TelerikTreeView  
        
            {  
        
                public partial class _Default : System.Web.UI.Page  
        
                {  
        
                    /// <summary>  
        
                    /// Variable for state maintein  
        
                    /// </summary>  
        
                    private RadTreeNodeCollection preChangeTreeNodes;  
        
                    protected void RadTreeView1_ContextMenuItemClick(object sender, RadTreeViewContextMenuEventArgs e)  
        
                    {  
        
                        RadTreeNode clickedNode = e.Node;  
        
                        // Copy Nodes  
        
                        this.CopyRadTreeNodesTo(out preChangeTreeNodes);  
        
                        .....  
        
                    }  
        
                    /// <summary>  
        
                    /// The state of present TreeView is copied onto the RadTreeNodeCollection object of the argument.  
        
                    /// </summary>  
        
                    /// <param name="nodes"></param>  
        
                    private void CopyRadTreeNodesTo(out RadTreeNodeCollection nodes)  
        
                    {  
        
                        nodes = new RadTreeNodeCollection(this.RadTreeView1);  
        
                        foreach (RadTreeNode node in this.RadTreeView1.Nodes)  
        
                        {  
        
                            nodes.Add(node.Clone());  
        
                        }  
        
                    }

The following error occurs by the second post backing.

-----------------------
Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.
-----------------------

The error will not occurs when EnableViewState property of TreeView is false.
But I don't want to change EnableViewState to false. Beause I can not get RadTreeViewContextMenuEventArgs Value when it is false.
Also SessionState mode is SQLServer, I can not use session to maintain the node.
How to keep the node during page post-back?

RadGrid Filter with Template column

Hello Team,

I created a Rad grid with a GridBoundColumn which is assigned a DateTime column. I have the allowFilterOnColumns= True.

Since it is a template column i have added a RadDatePicker as said in the demo of basic template filtering.

But the filter is not working.

Here is the code i have now.
