Hi.

 My question is: How to avoid the "null" text on columns that are nullable?

Example: My model is:

[KnownType(typeof(ReferralViewModel))]
public class ReferralViewModel
{
    [ScaffoldColumn(false)]
    public int Id { get; set; }
 
    [ScaffoldColumn(false)]
    public int Rut { get; set; }

    [Required(ErrorMessage = "Campo obligatorio")]
    [DisplayName("Observación Actual")]
    [DataType(DataType.Text)]
    public string AtencionObservacion { get; set; }

    [DisplayName("Detalle Interconsulta")]
    [DataType(DataType.Text)]
    public string DetalleInterconsulta { get; set; }
}

As show, DetalleInterconsulta is not requiered, and the posible values are null, empty or an string. When the user leave blank the field and insert it the grid show the row good. But when the user click the Edit Button, the blank field show "null". If I see the BD, sometimes the field is save as string "null" (not the NULL value).

This happens with all fields that are not required and the type is string. I'm using the last version of Telerik (2010.2.825.235).

I attach images for view.

Thanks.

Hi Daniel,

This issue will be fixed with the next official release of Telerik ASP.NET MVC components. The workaround is to hook up to the OnEdit(...) event and set appropriate value for the TextBox(or other controls).

Hi Hristo and Jigar,

Could you confirm whether this issue should be resolved in version 2010.2.902? I am using it and the issue is still present. I am using PopUp as my edit mode, if that makes any difference.

Best regards,

Erik
