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

I have a horizontal splitter with a top pane and a bottom pane. Normally I can slide the splitBar up and down. However, if I have a binary component in one of the panes, I cannot slide the splitBar over it. Please try the simplified sample code below, and please help me find a solution. I have been trying to figure this one out for some time.
| <telerik:RadScriptManager ID="RadScriptManager1" runat="server"> |
| </telerik:RadScriptManager> |
| <telerik:RadSplitter ID="splitter1" Orientation="Horizontal" Width="100%" Height="100%" runat="server"> |

| </telerik:RadPane> |
| <telerik:RadSplitBar ID="splitBar1" runat="server" /> |
| <telerik:RadPane ID="paneBottom" runat="server" Width="100%" Height="100%" ContentUrl="RadGridExport.pdf"> |
| </telerik:RadPane> |

Greetings,
I like the scheduler, but we have some specific customizations required.
1) how to get the left side of the Schedule to be reserved for doctors' hours, e.g. we want the person making appts to visually see that, e.g., Dr. John has business hours from 3 - 5 pm, for example. This could look like an appt block, but is not one at all. And there may be 4 or 5 of these reserved appointment-looking blocks - each in a different color.
2) Also, how do I populate the header of the Day Schedule (this is on the same level as "all day" header)? What's the property.
Many thanks,
Randy Smith

Hey Guys,
I am using a Radscheduler control that edits and Inserts using an advanced custom form.
All works great however I would like to make the start and end time visible in the MonthView because we need user to specify time not only date. Currently if i double click a target slot the advanced insert form appear with only start and end date.
Can you please advise.
Best regards,
Maged

Hello guys.
I'm trying to use this example (without image column, very simple), but I'm setting its datasource by a c# method. The grid is binded correctly and the action started by the "add new record" button, showing all fields to insert a new record. However, the edit and delete button gave me this exception:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
and the insert button do nothing.
First: How can I to know the name of controls showed in the insert action?
Second: What's the event fired by Edit and the delete button? I tryed to put a breakpoint in the: RadGrid1_UpdateCommand, RadGrid1_EditCommand, RadGrid1_ItemDeleted, RadGrid1_DeleteCommand, but the system doesn't break at breakpoint.
Tx in advance.
Regards.
