Hi,

I'm using richtextbox with TelerikEditor and have come across the following problem. If I use Text Highlight Color on my text, the highlight color is not saved. ie when reloading the record which was saved in xaml the highlight is gone. Any one else come across this one.

Thanks,
Karl

I have a TreeView that I would like to display a set of objects where they each contain a list<> or BindingList<> of objects of the same type as the base class. It is a recursive type. I am having a hell of a time getting this list to display anything other than the root list. The more I tinker with the ChildMember or DisplayMember I get either nothing displayed or I get an error:

System.InvalidOperationException was unhandled

Hi,

I am currently evaluating the radgridview in UNBOUND mode.

I have used .Relations.AddSelfReference which works in my scenario very well

My question is, is it possible to make the indent smaller for the sub rows

+ My Top Row
        My Top Rows Relation #1
        My Top rows Relation #2

I would like to make this indent smaller

+ My Top Row
    My Top Rows Relation #1
    My Top rows Relation #2

Thanks

Reporting what I think might be a bug.
When using a RadScheduler (2011 Q3) in MonthView, CellClick event of RadScheduler does not fire when a cell (corresponding to a day in monthview) is clicked. It fires only when the smaller day header is clicked.
One can overcome this issue by using RadScheduler MouseClick event like this:

Hi,

I've been following this example which works great
:
http://www.telerik.com/help/winforms/scheduler-appointments-and-dialogs-drag-and-drop-from-another-control.html

What I would like to do is once I have dropped the appointment I would like the apppointment dialog box to open so I can enter some addtional data. I am also using the CustomEditAppointmentDialog example so I can use my own fields etc.

Is this possible, I've tried firing the _AppointmentEditDialogShowing event but can't pas the appointment details ie times etc it comes up with a invalid cast.

Thanks
