Hi,
I'm developing a page for edit values.
I've this code:
....
<td>
<asp:DropDownList ID="ddlAAConGas" runat="server" SelectMethod="GetEmpresasGN" DataTextField="Nombre" DataValueField="IdEmpresa" SelectedValue='<%# Item.AAConGas %>' />
</td>
<td>
<ej:DatePicker ID="dateFechaConcesionGND" runat="server" WatermarkText="Seleccione Fecha" DateFormat="dd/MM/yyyy" Value='<%# (Item.FechaConcensionGND) %>'/>
</td>
......
<div align="center">
<asp:Button ID="btnAceptar" runat="server" Text="Aceptar" OnClick="btnAceptar_Click" Width="100" />
<asp:Button ID="btnCancelar" runat="server" Text="Cancelar" OnClick="btnCancelar_Click" Width="100" />
</div>
The page load values perfectly, but when I click on btnAceptar, I get an exception: "System.NullReferenceException' in App_Web_btt5vogx.dll" on datepicker control, the item is null, but Drop Down List load data perfectly.
Ah, The property FechaSolicitudGND is DateTime?
Any idea?
