This RadDatePicker calendar control works in standard ASP INSERT record form.

          <td style="width:90px;">
            <TRad:RadDatePicker ID="dpDATE_INSTALLATION_INSERT" runat="server"
                                SelectedDate='<%# Bind("DATE_INSTALLATION","{0:d}") %>' AutoPostBack="False">
              <Calendar ID="Calendar2" runat="server" Skin="Outlook" ShowRowHeaders="false"
                        BorderStyle="Solid" BorderWidth="1px" BorderColor="Black"
                        TitleStyle-Backcolor="PaleGoldenrod"></Calendar>
              <DateInput ID="DateInput2" runat="server"
                         DateFormat="dd-MMM-yyyy" DisplayDateFormat="dd-MMM-yyyy" ></DateInput>
            </TRad:RadDatePicker>
          </td> 

In the insert parameter I use the DateTime datatype.

When moved to AJAX Rad Grid form it fails when attempting to insert new record inthe Grid Form with error

"Conversion from string "" to type 'Date' is not valid."

I did not have to handle NULL or zero-length strings before.

Hi Kevin,

Try modifying the RadDatePicker declaration as below:

      <td style="width:90px;">
            <TRad:RadDatePicker ID="dpDATE_INSTALLATION_INSERT" runat="server"
                                DbSelectedDate='<%# Bind("DATE_INSTALLATION","{0:d}") %>' AutoPostBack="False">
              <Calendar ID="Calendar2" runat="server" Skin="Outlook" ShowRowHeaders="false"
                        BorderStyle="Solid" BorderWidth="1px" BorderColor="Black"
                        TitleStyle-Backcolor="PaleGoldenrod"></Calendar>
              <DateInput ID="DateInput2" runat="server"
                         DateFormat="dd-MMM-yyyy" DisplayDateFormat="dd-MMM-yyyy" ></DateInput>
            </TRad:RadDatePicker>
          </td>

DbSelectedDate is not available in the latest version of RadAjax DatePicker control.

Initializing the date in code behind fixed the NULL date error,
but then when I click Add New Record, the edit column disappears.  ARGG!!

Yes, Intellisense does not find it,
but it worked.

Thanks
