DatePicker Binding null reference

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?

Hi Manolo,

Thanks for using Syncfusion Products.

We are unable understand your use case scenario and unable reproduce the reported exception from the Datepicker control. Could you please confirm your use case scenario, whether you are using Datepicker control inside of a FormView and then tried to bind the value to this control or did you tried to get the value from DatePicker in code behind.

Please share us the issue reproducing sample with reproducing steps, otherwise modify the attached sample and share the same with us that would be helpful for us to analyze the problem and provide you prompt solution ASAP.

We have prepared the sample for accessing DatePicker value from the code-behind. Please find the sample in a below link:

Please let us know if you have further queries.

Thanks,
