Batch Edit with DatePicker

Is it possible to get a DatePicker as the editor when doing client-side batch editing? I've tried:

 and

<telerik:GridTemplateColumn HeaderText="1st Pmt. Due" UniqueName="FirstPaymentDate" DataType="System.DateTime" HeaderStyle-Width="100px" ItemStyle-Width="100px" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" AllowSorting="false"><br>                                <ItemTemplate><br>                                    <asp:Label runat="server" ID="date"Text='<%# Eval("FirstPaymentDate") %>'><br>                                    </asp:Label><br>                                </ItemTemplate><br>                                <EditItemTemplate><br>                                    <telerik:RadDateTimePicker ID="picker1" runat="server" DbSelectedDate='<%# Bind("date") %>'><br>                                    </telerik:RadDateTimePicker><br>                                </EditItemTemplate><br>                            </telerik:GridTemplateColumn>

 and in neither case do I get a DatePicker control when I click to enter edit mode.

I've searched extensively and haven't been able to find an example that does this. Is it possible? Can someone provide or point me to an example?​
