Javascript validation for datepicker

[Saran kumar]

hi im using the rad date picker from the below code. every thing works fine. but in validation im using the javascript.

<telerik:RadDatePicker ID="radPublishDate" runat="server" Style="margin-left: 0px;
                                                    z-index: 11000000000000;" ClientEvents-OnPopupOpening="PopupOpening" Height="12px"
                                                    Width="100px" Culture="English (United States)" Skin="Office2007" EnableMultiSelect="false">
                                                    <DateInput ID="publishDateInput" runat="server" Height="14px" DateFormat="MM/dd/yyyy"
                                                     DisplayDateFormat="MM/dd/yyyy">
                                                    </DateInput><Calendar ID="Calendar1" Skin="Office2007" UseColumnHeadersAsSelectors="False"
                                                        runat="server" UseRowHeadersAsSelectors="False" ViewSelectorText="x" ToolTip="Select Date"
                                                        ShowRowHeaders="false">
                                                    </Calendar>
                                                    <DatePopupButton HoverImageUrl="" ImageUrl="" />
                                                </telerik:RadDatePicker>

i just need to hide this and make the background as red on validation.

e.g im using javascript

$(

'ctl00_ContentPlaceHolder1_ucNote1_radPublishDate').SelectedDate == null  - is not working
$('ctl00_ContentPlaceHolder1_ucNote1_radPublishDate').style.visibility = 'hidden' - is not working
$('ctl00_ContentPlaceHolder1_ucNote1_radPublishDate').style.backgroundcolor = '#FF9F9F' -not working

please let me know the correct properties to achive these functionalites.
