RadTreeView postback performance

Does anyone know why RadTreeView would take 1.5 seconds to postback in a page, when regular TreeView takes .5 seconds? This doesn't happen in a simple demo project, just in my application page. What might be in my page that would cause postback to get delayed?

Thanks!
Andrew

[Solved] RadUpload Loose Input values

Hi

I have a grid that containt 2 user controls in the EditTemplate, one displays some info associated in a radgrid and the other is a radupload to upload some file to the the server. Each user controls contains a RadAjaxManagerProxy and the ASPX page contains a RadAjaxManager. My problem is that in some situation like sorting the grid and moving pages, the content of my radUpload include in the other user control simply disappears, so the user need to add the files to upload again. Is there a normal things that the content always disappears of it is simply my AjaxManager proxy that is not well configured ??? How i can keep theses values in the radupload control ???

If you need more details , please let me know.

Displaying fields

I have an edit window(pop up) that allows a user to create or edit a few fields. Access to this window either comes from selecting a record in a grid to edit or a create new record link.

If I select a previous record to edit, close the window and then click on the Create New Record link, the previous record's data is displayed momentary and then the correct empty fields are displayed. What is the proper way to not show any previous data?

[Solved] How to set Appointment.cssClass by Resource

I found your sample for setting the cssClass by Subject but I need to set it according to one of the resource ID's.

Here is the sample code from your documentation

Protected Sub RadScheduler1_AppointmentCreated(sender As Object, e As Telerik.Web.UI.AppointmentCreatedEventArgs)
   Select Case e.Appointment.Subject
      Case "McGregor"
         e.Appointment.CssClass = "McGregorStyle"
      Case "John Doe"
         e.Appointment.CssClass = "JDStyle"
      Case "Smith"
         e.Appointment.CssClass = "SmithStyle"
      Case "Anderson"
         e.Appointment.CssClass = "AndersonStyle"
      Case Else
   End Select
End Sub 'RadScheduler1_AppointmentCreated

My Appointment table schema is the standard demo table with the following added fields
Appointment
- AppointmentID
- Subject
- StartDate
- EndDate
- RecurrenceRule
- RecurrenceParentID
- LocationID
- RoomID
- GroupID

related tables
Location
- LocationID
- LocationName

Room
- RoomID
- RoomName

Group
- GroupID
- GroupName
- GroupColor

I need to set the e.Appointment.cssClass according to the GroupID field. I tried to figure it out but my OOP skills are considerably lacking.

Ideally I want to allow in our admin for the customer to set their own color, using the RadColorPicker, for each Group they create. Since it seems the related table data is also in the scheduler hierachy would it be possible to have it set the color automatically based on a new column Group.GroupColor field?
