Hello,

I need to have the ability to select the first row in a grid automatically and based on that selection two other radgrids gets populated. I was able to achieve the selection of the first row by doing the following in the prerender method.

This worked somewhat. (1) The two other grids are not populated when the autoselection happens, and (2) If i select another row in RadGrid1, the new selection is not kept and isntead the row from the prerender method is always selected.

I had all this working when a user comes in selects from a dropdown, but it seems that the client wants the first selection in the radcombobox to be automatically selected with the relevant data...

Any help would be tremendous, please!

SS

' PreRender Method

if (RadGrid1.MasterTableView.Items(0).Count > 0) Then

RadGrid1.MasterTableView.Items(0).Selected = True

End If

IIS7 WIN 2008 Telerik.Web.UI.WebResource.axd error 500

Dear Reader!

I have developed a simple ASP.NET AJAX Website running on ASP.NET 4.0.
It works fine on my development machine (Windows 7, IIS).

You can have a look at the site:

http://www.easyteamorganiser.com:82/

But depolying it to Windows 2008 Server, IIS 7.0 I can't get it to run properly.
It starts well, but by pressing the button it throws an client-side exception:

Thanks for help, Skim

I moved back to ASP.NET 2.0 (.NET 3.5). There it worked instantly.

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.

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)

        With oEvent

            .RecurrenceParentID = e.Appointment.RecurrenceParentID
            .Save()
        End With

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.
