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!

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.

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>
                <telerik:GridBoundColumn DataField="CompanyName" HeaderText="Unternehmensname" SortExpression="CompanyName"

            <Selecting AllowRowSelect="true"></Selecting>
        </ClientSettings>
 
 
 
 
    </telerik:RadGrid>

and the DataSources:

<asp:EntityDataSource ID="Companies" runat="server"
        ConnectionString="name=PortalEntities"
        DefaultContainerName="PortalEntities" EnableFlattening="False"
        EntitySetName="Companies" EntityTypeFilter="Company" EnableInsert="False" EnableDelete="False" EnableUpdate="False">
    </asp:EntityDataSource>
 
    <asp:EntityDataSource ID="Refinements" runat="server"

        DefaultContainerName="PortalEntities" EnableFlattening="False"
        EntitySetName="Refinements" EntityTypeFilter="Refinement" EnableInsert="False" EnableDelete="False" EnableUpdate="False">

    <asp:EntityDataSource ID="PaperTypes" runat="server"

    <asp:EntityDataSource ID="PrintTypes" runat="server"

    <asp:EntityDataSource ID="Products" runat="server"
        ConnectionString="name=PortalEntities"
        DefaultContainerName="PortalEntities"
        EnableFlattening="false"
        EntitySetName="Products" EntityTypeFilter="Product" EnableInsert="true" EnableDelete="true" EnableUpdate="true"
        Where="it.CompanyId = @CompanyId" Include="PrintType1, Refinement1, PaperType1">
        <WhereParameters>
            <asp:ControlParameter ControlID="rgCompanies" DefaultValue="1" Name="CompanyId" PropertyName="SelectedValue" Type="int64" />
        </WhereParameters>
    </asp:EntityDataSource>

But now I have a problem. When I try to add a new product in the second grid, it doesn't get the correct value for the value "CompanyId" in "Products". But it is needed, as it is a foreign key.

I'm quite stuck with this and I'm sure, the solution is quite simple. But nothing I tried yet, worked in any way.

So I would appreciate, if someone can help me out with this.

Yours

Hello!

We bought Telerik tools but still the next message in our proyect:

Thank you for using the Trial Version of Telerik UI for ASP.NET AJAX to build more powerful applications faster. Purchase the Commercial Version now to get access to all product updates and the Telerik expert support. 

What can we do to fix it?

Thank you.

We use RadTextBoxes in a form with a countdown timer for testing purposes.  After so much time elapses, if the user has not submitted the form, it is automatically submitted for him.

This form worked great until 1 or 2 updates ago when the RadTextBox started returning an empty value to the server on occasion.  Since the issue was sporadic we checked many other things before we finally realized it only happened when the form auto submitted.  Then we figured out it was a blur issue with RadTextBox.

In the meantime, this has caused us major problems as examinees type in an essay for 15 minutes and then it is all gone because they were not lucky enough to click outside the RadTextBox.

Now that we know what the problem is, we can work around it with a box.blur() or box.set_value(box.get_textBoxValue()) before postback.

I love these controls but this behavior is a serious breaking change and makes no sense.  There should be no requirement to blur a RadTextBox to get its value to the server.

Please fix this.

Thank you.

I suggest you to review your online demo in "Time picker/DateTime picker" section and add more demo/info re. RadDateTimePicker. Specifically, I would suggest:
  • Add "DateTimePicker - First Look"
  • MOST IMPORTANT: Add DateTimePicker range validation as it's different from TimePicker!

I have a RagGrid. On click of "Add New", I want a customized form. Is this possible?
I tried the following but did not work!
protected void _RadGrid1_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
       {
          if (e.CommandName == RadGrid.InitInsertCommandName)
          {
              e.Canceled = true;
              this._RadGrid1.EditIndexes.Clear();

              e.Item.OwnerTableView.EditFormSettings.UserControlName = "AddControl.ascx";
              e.Item.OwnerTableView.InsertItem();
          }          
      }

I'm doing some work in a javascript function and part of it is to remove (or add) an attribute from a RadTextBox.  Looking at the list of properties and methods on the Client Object page, I don't see how to do this.  I've seen forum posts reference the _textboxelement property of RadTextBox control like so:

<script type="text/javascript"
    function setToolTip() { 
        var RadTextBox = $find("<%= RadTextBox1.ClientID %>");  // Get the textbox client object 
        RadTextBox._textBoxElement.title = "Changed Tooltip"
    
</script>

I was wondering if this would work.  If so, how?

I'm trying to add or remove the data-bind attribute on a textbox.

Thanks.
