[Solved] Problem with Grid Ajax Rebind

[Daniel]

Hi.

I recently update to Telerik MVC 2010.3.1110.235. (released today).

My problem is that now the grid's ajax rebind don't work for me. When I delete an item, the grid don't refresh. I must click the "refresh button" to refresh the data.

My grid's are inside a TabStrip.

The Select, Add and Update works fine.

Any idea?

Thanks.

Hi Atanas.

My edit is in Inline Mode. I do a little research and I see when the item is deleted in the BD, and execute the rebind

//Rebind the grid
return View(new GridModel
{
  Data = _morbidHistoryRepository.GetPatientById(id)
});

the Json return an "Model Estate", and the refresh id not executed.

Firebug results:

Call: POST http://localhost:4080/MorbidHistory/_DeleteMorbidHistory?rut=17455432
Parameters: rut 17455432
Post: id=58&page=1&size=10&orderBy=&groupBy=&filter=

And the important response:

{"data":[{"Id":59,"Rut":17455432,"Nombre":"dfdfssfds","Tipo":"dfsdsdfsdfs","Fecha":"\/Date(1289876400000)\/","Observacion":null},{"Id":57,"Rut":17455432,"Nombre":"dsf","Tipo":"dsfds","Fecha":"\/Date(1289876400000)\/","Observacion":null}],"total":2,"modelState":{"Nombre":{"errors":["Campo obligatorio"]},"Tipo":{"errors":["Campo obligatorio"]},"Fecha":{"errors":["Campo obligatorio"]}}}

See that the Json return the fields validation, and It's cause that refresh view dont work (i think).

I attach images for view. See image2. Json return 2 item, the grid still show 3. And an object "ModelState" appears.

Thanks.

Hello Daniel,

 This is by design. If there are model state errors (validation didn't work) the grid is not rebound. Please make sure you don't have any validation errors.

Hi Atanas.

There are no validation errors.

This is the model for the grid:

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

    [ScaffoldColumn(false)]
    public int Rut
    {
        get;
        set;
    }

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

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

    [Required(ErrorMessage = "Campo obligatorio")]
    [DisplayName("Fecha")]
    [DataType(DataType.Date)]
    public DateTime? Fecha
    {
        get;
        set;
    }

    [DisplayName("Observación")]
    [DataType(DataType.MultilineText)]
    public string Observacion
    {
        get;
        set;
    }
}

But as I wrote, the problem is only with Delete. The validation only executed on Insert and Edit. It's strange happens when I delete an item. My Telerik build version is 1111, MCV 2.

Thanks.

Hello Daniel,

 This

{"Nombre":{"errors":["Campo obligatorio"]},"Tipo":{"errors":["Campo obligatorio"]},"Fecha":{"errors":["Campo obligatorio"]}}}

means that there are validation errors. You can check ModelState.IsValid with the debugger to verify this.
