Month Navigation & DayRender

[Dave Whiting]

Hi,

I'm using the DayRender event to set styles for holidays and weekends on a radDatePicker containing a calendar with autopostback = true. I've then used AjaxManager to cause the DayRender to fire when the fast-navigation 'next month' button is clicked on the calendar.

The problem I get is that the Ajax postback appear to fire but the calendar control (month view) disappears and the user has to click the calendar button on the datepicker again to bring it back. It does however display the next month which is what i needed. I need to stop the calendar hiding itself.

Any idea how I could fix or work around this?

Many Thanks
Mark

Hi Mark Broomfield,

A scenario where the calendar of the date picker has AutoPostBack set to true is not supported by RadDatePicker.

In order to implement the desired functionality, you could use the DayRender sever event of the calendar to customize the default calendar view. And implement the OnDayRender client-side event to customize the month view after navigation.

Find more about DayRender event in the following online resources:

My DayRender event doesn't fire when I navigate to another month... what's the fix?

Hi Peter,

Could you please elaborate more on which DayRender event does not fire the server-side or client-side? The server-side will be triggered if the AutoPostBack property of the calendar is set to true. As for the client-side in order to initially invoke the event you can do something like this:

ASPX:

<telerik:RadDatePicker runat="server"   ID="DatePicker1">
            <Calendar runat="server" >
              <ClientEvents OnLoad="Load" OnDayRender="RenderADay" />
            </Calendar>
         </telerik:RadDatePicker>

JavaScript:

function RenderADay(sender, eventArgs)

       {

          //your logic

       }
function Load(sender,eventArgs)

       {

           sender._moveToDate(sender.get_focusedDate(), true);

       }

All the best,

When I put AutoPostBack on the Date Picker's Calendar, the calendar pop-up displays when I click on it, but then the page posts-back and the pop-up closes. I've tried with both a RadAjaxManager and a RadAjaxPanel.

Hi Peter,

When setting AutoPostBack the behavior that you experiencing is expected as Iana explained in her post. I suggest that you use the client-side OnDayRender event instead of the server-side as it fits your requirements better.

Thanks for the reply Angel - As I said here, I'll just stick to using Special Days to get the behaviour I want and only use the DayRender event for the current month.
