GridEditableItem.UpdateValues() problem with GridMaskedColumn

I am having an issue when I use the following column in a grid:

<telerik:GridMaskedColumn DataField="Phone" HeaderText="Phone" UniqueName="Phone" Mask="(###) ###-####" />

In code behind:

protected void grid1_UpdateCommand(object sender, GridCommandEventArgs e)
{
GridEditableItem item = e.Item as GridEditableItem;
int licenseSponsorId = Convert.ToInt32(item.GetDataKeyValue("LicenseSponsorId"));
CDS.LicenseSponsor licenseSponsor = _db.Get<CDS.LicenseSponsor>(licenseSponsorId);
item.UpdateValues(licenseSponsor);
_db.Update(licenseSponsor);
}

The call to UpdateValues() results in "() -" being assigned to the Phone field when the user does not enter any input in the Phone field...

Is there a way to change this behavior?

Horizontal Bar Chart Issue

Hi Guys,

I have a horitontal bar chart with XAxis and YAxis2. YAxis2 Item labels appear on the top from left to right in ascending order. Take a look at the attached image. However, XAxis item labels start from bottom to top in ascending order. I want them to appear from top to bottom so that they look consitent with YAxis2 items labels. Is this possible?

Many thanks.
Irfan

Error On Delete With Recurrences

I have a scheduler set up with an object data source. I don't seem to have any problems binding the scheduler or making inserts or updates. The problem comes when I try to delete the first occurrence in a series. I get a bit of a cryptic error (below). If I delete the whole series or any of the other occurrences beside the first one, it works.

I also noticed when I look at the list of recurrences, the first item has a little red line between the Yen and Yang refresh icon. I also notice I do not have a value in the DataRecurrenceParentKeyField that I set - I've tried it both as a varchar and an int.

<-- Error -->
Cannot locate the parent of appointment with ID = '1'. Ensure that the parent appointment with ID = '' exists and is loaded.

<-- Code -->
<radPro:RadScheduler ID="rsEvents" runat="server"
            DataKeyField="EventModuleId"
            DataStartField="StartDateTime"
            DataEndField="EndDateTime"
            DataSubjectField="Title"
            DataRecurrenceField="RecurrenceRule"
            DataRecurrenceParentKeyField="RecurrenceParentID"
            AllowDelete="True"
            AllowEdit="True"
            AllowInsert="True"
            HoursPanelTimeFormat="h:mm tt"
            ShowAllDayRow="true"
            DataSourceID="odsEvents"
            Height="525"
            StartEditingInAdvancedForm="true" />

Protected Sub rsEvents_AppointmentInsert(ByVal sender As Object, ByVal e As Telerik.Web.UI.SchedulerCancelEventArgs) Handles rsEvents.AppointmentInsert
        Dim oAdmin As AdminPage = CType(Me.Page, AdminPage)
        Dim oEvent As New EventModule
        With oEvent
            .Title = e.Appointment.Subject
            .StartDateTime = e.Appointment.Start
            .EndDateTime = e.Appointment.End
            .RecurrenceRule = e.Appointment.RecurrenceRule
            .RecurrenceParentID = e.Appointment.RecurrenceParentID
            .Save()
        End With
    End Sub

VS 2012 crash after 2012 Q3 upgrade on Windows 8 (also on Windows 7 and VS 2010)

Computer: Windows 8, 64-bit, 8GB RAM

I upgraded my DevCraft 2012 Q2 SP2 installation to Q3 today and and VS 2012 is crashing after opening a solution. I have the following components installed:

RadControls for WinForms
RadControls for ASP.NET AJAX
RadControls for WPF
RadControls for Silverlight
KendoUI for ASP.NET MVC
MVC UI Extensions
Reporting
JustTrace
OpenAccess
JustMock

After installing, I started VS 2012 and took a very long time (perhaps 20 minutes) to get to a responsive state. I watched it in Task Manager and it looks like one core was pegged at 100% during this time and RAM consumed grew to over 500MB.

VS did come back eventually and I loaded a solution. Everything looked for a few seconds and then visual studio crashed. I tried rebooting and restarting VS but it crashes every time I try to load a solution. I went into the Windows EventLog and found this error:

Application: devenv.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.

at MS.Win32.HwndSubclass.SubclassWndProc(IntPtr, Int32, IntPtr, IntPtr)

I then restarted VS and instead of loading a solution, I tried running TELERIK\VS Extensions Options... This also failed with a dialog complaining about a missing resource (see the attached image).

I also installed the update on a Windows 7 64-bit machine with both VS 2010 and 2012 installed. VS 2010 did not have the excessively long startup time but it also crashed when I tried loading a solution. VS 2012 seems to be stuck loading a solution right now.

Looks like something is wrong with Kendo. I'm going to try uninstalling it.

While uninstalling all of the Kendo components on my Windows 8/VS2012 machine, I went over to the Windows 7 machine, launched VS 2012 and opened the Telerik\VS Extensions Options... I didn't get an error message this time but the dialog is messed up. See the attached image.

Update: After uninstalling all of the Kendo components on the Windows 8/VS 2012 machine, VS2012 was able to load a solution and work normally. On the Windows 7/VS2010 machine, I'm now seeing VS2010 crash whild loading a solition.

GridButtonColumn CommandName Delete

It must be very simple but I can't work it out
I've got a grid

<telerik:RadGrid ID="RadGrid1"

runat="server"

ShowHeader="False"

AutoGenerateColumns="False"

>

<MasterTableView

DataKeyNames="AppID, IDCart, IDOrder">

<Columns>

..............

<telerik:GridTemplateColumn UniqueName="TemplateColumn" >

<HeaderStyle Width="335px" />

<ItemTemplate>

<asp:Literal ID="myLiteral" runat="server" />

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridButtonColumn ConfirmText="Delete this product?" ConfirmDialogType="RadWindow"

ConfirmTitle="Delete" ButtonType="ImageButton" CommandName="Delete" Text="Delete"

UniqueName="DeleteColumn">

<HeaderStyle Width="15px" />

<ItemStyle HorizontalAlign="Center" CssClass="MyImageButton" />

</telerik:GridButtonColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

(myliteral is filled on temDataBound event.)
I bind the grid on code behind needdatasource event. It works fine.
If I click the GridButton to delete, raising RadGrid1_DeleteCommand event, it performs the delete function. It works fine

Now I just need to add Ajax to this.
so

<telerik:RadAjaxManager ID="RadAjaxManagerCart" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadGrid1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadGrid1" />

<telerik:AjaxUpdatedControl ControlID="myLiteral" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

It is not working. The RadGrid1_DeleteCommand event is performed, but it does not refresh the grid

Could you help me please?
