Questions on UI for WinForms Forum

I have a very large data set bound to the AutoCompleteBox and there is about a 5 second delay from when the user types some character until the AutoCompleteBox returns the suggestions. Is there a set of events I can subscribe to (e.g. AutoCompleteLookupBegin, AutoCompleteLookupEnd) or a method I can override so that when the look-up starts I can set a busy cursor or indicate to the user that the search is on going? As of right now this delay blocks the UI which isn't a problem as long as we let the user know something is happening.

Thank You,
Chris

[Solved] 3rd Level Hierarchy Difficulty

Hi,
I am trying for a while now to figur out what I have wrong in setting up my 3 level relation. I keep getting an unspecified error if I try to open the 3rd level. Am I missing a little detail?

Calendar WeekNummering

Good day Telerik Forums

i have a question relating the RadCalendar control.

for an application i am developing we needed to display Week numbers.
so after switching on Row headers in RadCalendar, we found out that the numbering does not correspond with our previous controls.

Is there a way to alter the numbering of weeks?
changing culture did not have (any) desired effect.

i have included a picture displaying the differences.
on a side note: in telerik weeks go almost always to 53(sometimes to 54) and always start at 2 unless the year starts on a monday.

thanks in advance and with kind regards!

.NET4 Source Build

Hi

We build Telerik assemblies from source for redistribution as per your instructions here. In the VS2010 Release40 configuration the target framework is .NET Framework 2.0 by default.

Should we be changing the target framework to .NET Framework 4.0 in Release40 configuration prior to building? The reason I ask is twofold:

1) Would it be good practice in general?
2) We use Ngen as part of our application installation. If this is done on a machine without .NET2 installed (i.e. just .NET4 installed) the Ngen fails because it fails to find .NET2 dependencies.

Many thanks.

Adrian

How to create new appointment programmatically?

Dear Admin,

I have a RadScheduler with ActiveViewType = Day and RadScheduler1.GroupType = GroupType.Resource which my resources are my Employee.
I wrote this code to create an appointment, but it does not work and my RadScheduler does not show the appointment:

Private Sub NewAppointment(ByVal StartDateTime As Date, ByVal EndDateTime As Date, ByVal EmployeeID As Integer)
    Dim duration As Long = DateAndTime.DateDiff(DateInterval.Hour, StartDateTime, EndDateTime)
    Dim apt As New Appointment()
    apt.Start = StartDateTime
    apt.End = StartDateTime.AddHours(duration)
    apt.Summary = "Summary Test"
    apt.ResourceId =
    New EventId(EmployeeID)

    'RadScheduler1.Appointments.Add(apt)

    RadScheduler1.ActiveView.Appointments.Add(apt)
End Sub

What did I wrong?

I am looking forward to hearin from you as soon as possible.
Thank you in advanced.
Kian
