Change cell background image / color
I have two schedulers. One is for users to populate with appointments. The second one is public facing. They both share the same data source though. For the public facing, as the scheduler loads and populates events I need to do the following:

- check the appointment subject. (For simplicity) If the subject is "A" then I set the background image of the cell to a color and an image
- if the subject is "B" I set it to another image and color
- I need to set the whole background image of the cell in month view. Not the background image and color for the appointment. The whole cell.
- I need to then also make the appointment invisible so that only the color and image remain.

I tried doing this in the OnAppointmentCreated event. I have the code below but this only sets the color of the appointment and not the whole cell. It also for some reason does not hide the appointment. Any help would be appreciated.

protected void RadScheduler1_AppointmentCreated(object sender, Telerik.Web.UI.AppointmentCreatedEventArgs e)
{          
            if(e.Appointment.Subject.ToString() == "A")
            {
                e.Appointment.CssClass = "Custom";            
                e.Appointment.Visible = false;
            }
}

the css:
<style type="text/css">  
    .Custom .rsAptOut  
    {  
         background-color: Blue !important;  
    }  
    </style>

Radtabstrip themes issue
I am working on a site that was using Qx 2008 controls.  In the process of working on the site, I migrated the controls to Q1 2009.  In the process the "gray" them was no longer available so I had to switch themes on the radtabstrip.  Any theme I select has a visual tab problem where the left x number of pixels are elevated above the rest of the tab.  See attached JPG.

Client side grouping and collapse/expand by default
Hi,

I can't figure out how to make use of the GridGroupLoadMode.Client, define groups on the server and at the same time selectively collapse certain groups when the grid initially loads.  I'm loading the groups just fine, but when I try to set groupHeader.Expanded = false in the Pre_Render event, I get javascript errors and things don't work right afterwards (context menu doesn't expand, date picker for the filter box does not show, etc).  Do you have an example of how to achieve this?

Questions: How do i register Client Events? I tried doing in Page_Load, but system threw an exception because it is not able to find getCurrent(this.page)
I want to export with "ExportOnlydata" = true and "IgnorePaging" = true, In doing so i get excpetion, which i think is because child grid data is not available (since it gets loaded only on Grid ItemCommand event).

I would really appreciate if you could look into my code and suggest me how to implement "Export to excel" functionality in this case.

Thanks,

Hide Notification Control

I am using the Notification control to alert our users that are logged into our system of when we will be doing maintenance. I plan on using a simple text file (server side) that will have the contents to display. If the file has text, the notification will display it to the user. If the file is empty, then do not show the notification to the user. I have code in the "OnCallbackUpdate" sub to read the file. If the message is empty I set the notification control to visible = false. However, it still shows up on the screen. How do I make it not show when there isn't any text to display?

<telerik:RadNotification ID="RadNotification1" runat="server" LoadContentOn="EveryShow"
    ShowInterval="6000" OnCallbackUpdate="OnCallbackUpdate" Position="Center" VisibleTitlebar="False"
    AutoCloseDelay="5000" EnableRoundedCorners="True" EnableShadow="True" Skin="Office2010Black">
</telerik:RadNotification>

Protected Sub OnCallbackUpdate(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadNotificationEventArgs)
    Dim sMsg As String = ""
    Dim sr As System.IO.StreamReader = New System.IO.StreamReader("C:\temp\TextFile1.txt")
    sMsg = sr.ReadToEnd
    sr.Close()
    If Not String.IsNullOrEmpty(sMsg.Trim) Then
        RadNotification1.Text = sMsg
    Else
        RadNotification1.Visible = False
    End If
End Sub
