When I have a RadDatePicker on a page that has Enabled = "false", the rendering causes an increased page size. Making it enabled again makes the problem go away.
Further more, if I make the dateinput portion of the raddatepicker invisible, the problem goes away.
Using Telerik 2012.1.215.40.
Here's the markup
<telerik:RadDatePicker ID="RadDateStart" Width="180px" EnableTyping="false" runat="server" EnableEmbeddedSkins="true" Enabled="false"> <Calendar ID="Calendar1" UseRowHeadersAsSelectors="False" runat="server" UseColumnHeadersAsSelectors="False" ViewSelectorText="x" EnableEmbeddedSkins="true"> <SpecialDays> <telerik:RadCalendarDay Repeatable="Today" ItemStyle-BackColor="#BCDDFF" /> </SpecialDays> </Calendar> <DateInput ID="DateInput1" DisplayDateFormat="MMM dd, yyyy" runat="server" DateFormat="M/d/yyyy" ReadOnly="True"> </DateInput> <DatePopupButton ImageUrl="" HoverImageUrl=""></DatePopupButton></telerik:RadDatePicker>
