I am gettting a performance problem with the RADCalendar control.  When one scrolls to a different month a postback occurs.  I need a postback only on selected date changed.

Hi Phil Huhn,

One suggesction to achieve this functionality is, set the AutoPostBack property to true on client side in "OnDateSelected" eventhandler and then set the "AutoPostBack" to false from the server side in PageLoad event.

ASPX:
<telerik:RadCalendar ID="RadCalendar1" Runat="server" AutoPostBack="true">  
    <ClientEvents OnDateSelected="OnDateSelected" /> 
</telerik:RadCalendar> 

JavaScript:
<script type="text/javascript">  
function OnDateSelected(sender, eventArgs)  
{  
    sender.set_autoPostBack(true);  
}  
</script> 

C#:
protected void Page_Load(object sender, EventArgs e)  
{  
    RadCalendar1.AutoPostBack = false;  


Thanks,
Princy.

That is a cool interplay between client and server side!  I have a feeling the above solution is used in many other situations.  So, I renamed the JavaScript function to 'OnChangePostBack' and placed the script in the master-page.

Hi,
Just found this thread and I'm using the approach to. Nice!
But I think it should be integrated into the calendar with a property, like: EnableOnlyClientSideNavigation=true/false

Regards,
Mattias
