RadDatePicker Null value Issue

[Ramesh]

Hi All,

I have webform with three bread crumbs for a registration process.

All the three bread crumbs are in a single webpage with different views in it. In first view these two RadDatePicker controls (one exam start date and other exam end date).

In edit mode these RadDatePicker.SelectedDate are becoming null so, I am facing an issue/Error "Nullable object must have a value"

Please help on it.

regards,
R

Please find the code below:

<telerik:RadDatePicker ID="startDate" runat="server" Width="90px" Calendar-ShowRowHeaders="false" AutoPostBack="true">
                                                <DateInput ReadOnly="true">
                                                </DateInput>
                                                <Calendar>
                                                    <SpecialDays>
                                                        <telerik:RadCalendarDay Repeatable="Today" ItemStyle-CssClass="rcToday" />
                                                    </SpecialDays>
                                                </Calendar>
                                            </telerik:RadDatePicker>
                                            <asp:RequiredFieldValidator ControlToValidate="startDate" Display="None" ErrorMessage="start Date Required"
                                                ValidationGroup="ED" SetFocusOnError="true" runat="server" ID="RequiredFieldValidator9"></asp:RequiredFieldValidator>

<telerik:RadDatePicker ID="EndDate" runat="server" Width="90px" Calendar-ShowRowHeaders="false" AutoPostBack="true">
                                                <DateInput ReadOnly="true">
                                                </DateInput>
                                                <Calendar>
                                                    <SpecialDays>
                                                        <telerik:RadCalendarDay Repeatable="Today" ItemStyle-CssClass="rcToday" />
                                                    </SpecialDays>
                                                </Calendar>
                                            </telerik:RadDatePicker>
                                            <asp:RequiredFieldValidator ControlToValidate="EndDate" Display="None"
                                                ValidationGroup="ED" ErrorMessage="End Date Required" SetFocusOnError="true"

Hi Ramesh,

I have created a sample web site to test the described behavior using the provided code snippet. On my side the validation works as expected after configuring the ValidationGroup and Display properties of the validators. Please run the attached application and let me know about the result.
