Adding custom field to Scheduler error casting to IEvent

Hello,

I've gone through the tutorial here: http://www.telerik.com/help/winforms/scheduler-appointments-and-dialogs-adding-a-custom-field-to-the-editappointment-dialog.html. I have been able to add my custom field to the scheduler, however when I run the application I get the following error:

Unable to cast object of type 'RadSchedulerDemo.GuardianAppointment' to type 'Telerik.WinControls.UI.IEvent'

This error occurs in the custom AppointmentFactory class I created, as directed by the tutorial, within the CreateNewAppointment function. I've searched for an answer to this issue but have not been able to find anything related to it.

Any ideas on what could be the problem?

ReadOnlyChanged

Hi,

I have a problem with RadRadioButton and RadToggleSwitch.

I would like to change the look of the control depending on the ReadOnly state.

But I can not find an event ReadOnlyChanged.

I also try to catch all property changes, but no event is registered when I change the ReadOnly.

((Telerik.WinControls.UI.RadRadioButtonElement)(x.GetChildAt(0))).RadPropertyChanged += ...

((Telerik.WinControls.UI.CheckBoxLayoutPanel)(x.GetChildAt(0).GetChildAt(1))).RadPropertyChanged += ...

RadForm and TitleBorder Element

I am using the Visual Style Builder to make a theme based on the Metro Blue theme that is built-in. I am trying to change the color (currently light blue) that appears as the top border of all RadForms. However, when I go to RadForm->TitleBar->TitleBorder element and change the TopColor and TopShadowColor properties the RadForm Title bar is no longer displayed. I have attached before and after screenshots. I checked and some of the other property values change as a result of changing the TopColor property but I set them back to their previous values but the title bar is no longer displayed.

Am I missing something?

Tab key does not tab to next cell

I am using radgridview from Q1 2008 SP1.
The tab key was working till today afternoon, but now it doesn't work anymore.
The tab key was automatically transferring focus to the next cell for editing, but it has suddenly stopped to behave like this. Instead now the tab key simply ends the edit process for current cell but does not put the next cell into edit mode.
May be someone has solved this issue.
Any feedback would be greatly appreciated as I am on a very tight project deadline for this.

Thanks
