I am getting an error in the below code........what am I doing wrong ? 
-- error with this because of the conditional statement 
    <telerik:RadDatePicker  ID="radBillPeriodStartDate1" Skin="Office2007" Style="vertical-align: middle;"
                            runat="server" 
                            DbSelectedDate='<%# Bind("END_BILLING_PERIOD","{0:D}") == DBNull.Value ? radBillPeriodEndDate.SelectedDate : Bind("END_BILLING_PERIOD","{0:D}") %>'
                            >
                    
-- this works fine when there is no conditional statement 
 
     <telerik:RadDatePicker ID="radBillPeriodEndDate1"  Skin="Office2007" Style="vertical-align: middle;"
                            runat="server" DbSelectedDate='<%# Bind("END_BILLING_PERIOD", "{0:d}") %>'
                            >

ok thanks for that. Here is my problem , I have a raddatepicker bound to a radgrid. When I add a new item, I need to assign a datevalue from an existing control that I have on the page, and when the user edits this value, get that value saved to the database.
I have the following code which works but when a user edits it the value is not getting bound to the data, it resets it to 01/01/0001. Because there is no InsertItemTemplate in radGrid is there a way to achieve this ?

telerik:GridTemplateColumn HeaderText="Billing Period Start Date" UniqueName="BEGIN_BILLING_PERIOD"

EditFormColumnIndex="1">

<asp:Label runat="server" ID="lblBillingPeriodStartDate" Text='<%# Eval("BEGIN_BILLING_PERIOD", "{0:D}") %>'></asp:Label>

</ItemTemplate>

<telerik:RadDatePicker ID="radBillPeriodStartDate1" Skin="Office2007" Style="vertical-align: middle;"

runat="server" DbSelectedDate='<%#GetDateValue(Convert.ToDateTime(DataBinder.Eval(Container.DataItem, "BEGIN_BILLING_PERIOD")))%>'

</telerik:RadDatePicker>

</EditItemTemplate>

</telerik:GridTemplateColumn>

protected

DateTime GetDateValue(DateTime d)

{

DateTime retValue;

if (d == null)

{

retValue =

DateTime.Parse(radBillPeriodEndDate.SelectedDate.ToString());

}

else

{

retValue = d;

//Convert.ToDateTime(d, "{0:d}");

}

return retValue;

}
