Dear Sir,
I have to insert appointments in the website (web control) and retrieve the appointments in the windows application (win control). Is it possible ?
i am using both the web & win rad controls for a same project which is created in the web & now it it converting that same project as window application. In that, RadSchedule control in both web & win rad control's recurrence rule field 's (format) data is varying while inserting a new appointment. But i am using a single database (sqlserver 2005). Can i insert same type of recurrence rule field 's (format) data in both.
Please reply as soon as possible..

Hello all -
I am new to using the Telerik controls and am encountering a problem that I cannot seem to find a solution to. It's probably a simple fix and am hoping someone can point me in the right direction. I have added the RadAjaxPanel and a panel bar to one of my pages. Withing the ItemTemplate tags I have added a div with several labels and textboxes. When I look at the page in design view or through a browser the text for the labels does not appear? If I highlight the area in a browser I can see the text so it appears the its being rendered with the text color set to white. If in design view I set the skin attribute to "Default" then the text shows up.
Any thoughts?
Thanks in advance!

I'm getting the following error and I can' track down the reason. I have a screen where the user selects criteria. I build the query behind the scenes for the onneeddatasource event when they click search. On initial load I just display a dummy grid. When I click on search the page postback, assembles and runs the query and returns the correct grid as expected. If I click on search a second time or peform any type of post back I get the Failed to load viewstate.
Hopefully you can help me solve this mystery. Thanks

One of our key customers is having performance issues with our Scheduler. They mainly manifest themselves by locking up the Scheduler and occasionally crashing the browser that it is open within.
We have investigated this and found that whenever the mouse is moved around within the Scheduler, the memory and CPU resources spike, often to 100%. This is not while dragging or anything. Though we have a lot of custom client code, it looks to be caused by client mouse events that are native to the Scheduler control.
Has anyone else experienced similar issues?
Is it possible to turn off some/all of the Schedulers client events?
Are there any recommended best practices surrounding this?

Hi All,
I'd like to conditionally have a couple of images shown along with the subject of an appointment. To that end I tried putting the following code into the subject from the AppointmentDataBound event.
| Dim subject As String = e.Appointment.Subject |
| subject += " - " & dataRowView.Item("Title").ToString() |
| Dim Status As Integer = 0 |
| Status = CInt(dataRowView.Item("Status")) |
| Dim errorImages As String = "" |
| If Status = 1 OrElse Status = 3 Then |
| errorImages = "<img src=""/images/icons/16/not_ok.png"" border=""0"" />" |
| End If |
| If Status = 2 OrElse Status = 3 Then |
| errorImages += "<img src=""/images/icons/16/not_ok_orange.png"" border=""0"" />" |
| End If |
| e.Appointment.Subject = errorImages & subject |
When this executes it works but the <img... is rendered as text in the appointment. Is there a way to use this method to get the images rendered?
I could use a AppointmentTemplate but given that the Status flag can affect two images I'm not sure how I could do it. Any pointers?
Regards,
Jon

Hello,
I would like to know if it's possible to have a new column (on the left) in the month view where it's written the number of the week.
And in this column, have a dropdownlist to switch ressources for example.
Thank you
