Problem with Sorting on a Grid that has Nested Items

We have a problem with the RadGridView, when we have at our top level a collection full of "GroupDto"'s..
Below this we have "GroupMemberDto" Items...

so in our list we potentially have for example...

- GroupDto 1
          - GroupMemberDto 1
          - GroupMemberDto 2
+ GroupDto 2
- GroupDto 2
          - GroupMemberDto 3
          - GroupMemberDto 4
          - GroupMemberDto 5
          - GroupMemberDto 6
- GroupDto 4

So the problem occurs, when we have a top level item selected say "GroupDto1" and "GroupMemberDto1" selected....

then the problem occurs if we try to sort by one of the fields on GroupMemberDto... we get the following error
"Unable to cast object of type 'BusinessPort.Agility.Core.Shared.DataTransferObjects.GroupMemberDto' to type 'BusinessPort.Agility.Core.Shared.DataTransferObjects.GroupDto'."

a copy of the call stack we get is...

The debug source files settings for the active solution indicate that the debugger will not ask the user to find the file: c:\TB\102\WPF_Scrum\Release_WPF_40\Sources\Development\Controls\GridView\GridView\GridView\GridViewDataControl.Scrolling.cs.

The debugger could not locate the source file 'c:\TB\102\WPF_Scrum\Release_WPF_40\Sources\Development\Controls\GridView\GridView\GridView\GridViewDataControl.Scrolling.cs'.

Hope this all makes sense, Let me know if you have any suggestions on how we can solve this, or if you require further information?

Bug in RadGridView: CurrentCell not in sync with SelectedCells / SelectedRow

Hi,

I have a experienced a lot af problems when using SelectionUnit FullRow. The CurrentCell property does not seem to be in sync all the time with the SelectedCells / SelectedRow properties. I have frequent cases where this happens but these are difficult to reproduce.
I have one case though were I could always reproduce this: when cancelling the selection in the SelectionChanging event. When doing so the CurrentCell is still set to another row and when clicking this same cell a second time there are no Selection events any more.

I use version 2011.2.920.40 of the Telerik WPF library.

A sample solution can be downloaded here.

how to customize AppointmentSourceWarning text

Hi there,

Is there a way to replace the AppointmentsSource warning text?
Can I do that without the need to implement a custom ScheduleView theme?

Here is my situation - I have a RadScheduleView that is bound to the VM for Appointments.
When I load my form, the VM takes about 5 seconds to fetch the Appointment data.
Everything looks good and works fine after the 5 seconds load.
But, in the first 5 seconds there is a big "Please provide AppointmentsSource" and I don't know how to customize that message.

I hope to show a "Loading..." message instead of the default AppointmentsSource warning text.

Any ideas on a good approach for this situation?

Thanks in advance.

AppointmentStyleSelector strange behavior

Hi

I'm using trial version of WPF controls (Q3 2011) and trying to implement custom appointment style as it described here
It works well until I want to resize an appointment (please see attached screenshot). The problem is that if I use custom AppointmentStyleSelector I can't resize Appointment rectangle by dragging top or bottom edge anymore, right and left edges are highlighted for resizing instead. Usage of OrientedAppointmentItemStyleSelector as AppointmentStyleSelector leads to the same results.
So could you please help me to figure out how to fix that issue?

Here is a link to the demo project http://dl.dropbox.com/u/3950376/TelerikAppointmentStyle.zip

Thanks,
Alexander
