Set SelectedDate RadDatePicker in Edit Form in RadGrid

[Yefta]

Hi, i have a RadDatePicker in EditForm in RadGrid.

The column in RadGrid consist of EditButtonColumn, Name, StartDate, EndDate.

when i click Edit, it shows error:

Sys.WebForms.PageRequestManagerServerErrorException: Specified cast is not valid.

I assume this is because the value StartDate and EndDate is empty/null.

my code to assign the value to RadDatePicker is like this:

<telerik:RadDatePicker ID="radStartDate" runat="server" Culture="en-US" TabIndex="8" Skin="MetroTouch" SelectedDate='<%# Bind("StartDate") %>'>
    <Calendar ID="Calendar1" runat="server">
        <SpecialDays>
            <telerik:RadCalendarDay Repeatable="Today" ItemStyle-BackColor="Yellow">
            </telerik:RadCalendarDay>
        </SpecialDays>
    </Calendar>
    <DateInput DisplayDateFormat="d/M/yyyy" DateFormat="d/M/yyyy" LabelWidth="40%" TabIndex="6">
    </DateInput>
</telerik:RadDatePicker>

<telerik:RadDatePicker ID="radEndDate" runat="server" Culture="en-US" TabIndex="9"  Skin="MetroTouch" SelectedDate='<%# Bind("EndDate") %>' >
    <Calendar ID="Calendar2" runat="server">
        <SpecialDays>
            <telerik:RadCalendarDay Repeatable="Today" ItemStyle-BackColor="Yellow">
            </telerik:RadCalendarDay>
        </SpecialDays>
    </Calendar>
    <DateInput DisplayDateFormat="d/M/yyyy" DateFormat="d/M/yyyy" LabelWidth="40%" TabIndex="6">
    </DateInput>
</telerik:RadDatePicker>

How to set RadDatePicker, when there's no value, shows no error. And if there's a value, the value of StartDate and EndDate will set to TextField and SelectedDate in RadDatePicker 

 

Thank you very much
