RadGrid ASP.NET - IE issue with MultiCell selection mode

Hi guys,

I'm having an issue with MultiCell selection mode within a RadGrid.
After I select some cells, I can't select any text inside any textbox of the whole page.

You can reproduce this bug even in this official demo page:
https://demos.telerik.com/aspnet-ajax/grid/examples/functionality/selecting/cell-selection/defaultcs.aspx
(I have this kind of problem only with Internet Explorer 9+)

Any suggestion or workaround?

Thanks
Giuseppe

AsyncUpload Invalid Characters

I am not sure if it has to do with our recent update to 2014.1.225 or if it is only recently that our Mac users have started attempting to upload files with characters that are invalid on our windows server, but errors have been occurring as a result of this. I then noticed that the latest release specifically states that such a scenario was addressed to allow the upload of these files. I updated to this version and the same errors continue to occur. Even attempting to upload these files with invalid characters from a mac on the telerik demos do not work. The file does not succeed or fail it just sits there and throws a javascript error about an invalid token. While this is different from what we are experiencing it still seems like this does not function correctly in 2014.1.403. Is there something new that needs to be configured in order to make this work?

I have attached a screen of the errors thrown in the developer tools from our site when attempting to upload such a file in Safari on Mac. Has anyone else run into this or something similar?

Thanks!
Jon

Having issues in Telerik's RadScheduler when using recurrence fields and events

I am using RadScheduler for showing/creating the Appointments in my Database.
My code is working fine (Create, Retrieve, Update, Delete) as long as I have non-recurring Appointments. But, as soon as a recurring type Appointment comes in account, everything stops working and I get following error on postback:
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.

What am I doing wrong here?
Following is my code, On .ASPX page:

<asp:Content ID="BodyContent" ContentPlaceHolderID="MainContent" runat="server">

<telerik:RadScheduler ID="RadScheduler1" runat="server" TimeZoneOffset="00:00:00" AdvancedForm-EnableCustomAttributeEditing="true"

SelectedView="MonthView" OverflowBehavior="Expand" StartInsertingInAdvancedForm="true" EnableViewState="true"

DataKeyField="AppointmentID" DataStartField="CalendarStartDateTime" DataEndField="CalendarEndDateTime"

DataSubjectField="AppointmentBody" DataRecurrenceField="RecurrenceRule" DataRecurrenceParentKeyField="ParentAppointmentID"

DataReminderField="Reminder" OnAppointmentCreated="RadScheduler1_AppointmentCreated" OnAppointmentInsert="RadScheduler1_AppointmentInsert"

OnAppointmentUpdate="RadScheduler1_AppointmentUpdate" OnAppointmentDelete="RadScheduler1_AppointmentDelete"

OnRecurrenceExceptionCreated="RadScheduler1_RecurrenceExceptionCreated" OnReminderDismiss="RadScheduler1_ReminderDismiss"

OnReminderSnooze="RadScheduler1_ReminderSnooze">

<AdvancedForm Modal="true"></AdvancedForm>

<Reminders Enabled="true" MaxAge="5"></Reminders>

<TimeSlotContextMenuSettings EnableDefault="true"></TimeSlotContextMenuSettings>

<AppointmentContextMenuSettings EnableDefault="true"></AppointmentContextMenuSettings>

</telerik:RadScheduler>

</asp:Content>

And Code on .CS page:

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

BindAppointments();

}

private void BindAppointments()

{

try

{

List<AppointmentEN> lstAppointment = AppointmentProvider.GetAppointments();

foreach (var item in lstAppointment)

{

item.RecurrenceRule = string.IsNullOrWhiteSpace(item.RecurrenceRule) ? null : item.RecurrenceRule;

item.ParentAppointmentID = item.ParentAppointmentID == 0 ? null : item.ParentAppointmentID;

}

RadScheduler1.DataSource = lstAppointment;

RadScheduler1.DataBind();

RadScheduler1.SelectedView = SchedulerViewType.MonthView;

RadScheduler1.SelectedDate = DateTime.Now;

//RadScheduler1.Visible = true;

}

catch (Exception ex)

{

}

I have found that doing EnableViewState="false" does the job, but I don't want to do that because then other functionalities like Rescource editing stops working correctly.

Bindind hidden properties between two grids

Hello together,

as this is my first post on this forums and am new to telerik components, please be gentle, if this is a dumb question. ;-)

I try to use two RadGrids which are linked together:

<telerik:RadGrid ID="rgCompanies" runat="server"
        AllowPaging="True" AllowAutomaticUpdates="False" AllowAutomaticInserts="False"
        AllowAutomaticDeletes="False" AllowSorting="true"
        DataSourceID="Companies">
        <MasterTableView AutoGenerateColumns="False"
            DataKeyNames="CompanyId">
            <Columns>
                <telerik:GridBoundColumn DataField="CompanyId" HeaderText="Nr." SortExpression="CompanyId"
                    UniqueName="CompanyId" Visible="true" ReadOnly="true" MaxLength="5">
                </telerik:GridBoundColumn>
