Upload/Submit HttpPostedFileBase has zero files

I am using the "Basic usage" of the Upload control in ASP.NET MVC and Internet Explorer version 9.0.8112.16421

After I select the file to upload and click "Submit", my Submit() action is indeed called, but "IEnumerable<HttpPostedFileBase> files" contains zero files in the called method:

public ActionResult Submit(IEnumerable<HttpPostedFileBase> files)
{
:
:
}

How can I get the actual files to be uploaded?

Thanks.

[Solved] Icons for components are too high (kendo+bootstap 3)

All of the icons that are placed on the kendo controls are a bit too high (see attached images). I believe this started when I installed bootstrap, but I am not sure of the best fix.

Thanks

[Solved] Filtering Grid by Dropdown

Hello,

I need to reload the grid based on a dropdown change but I don't want to do the filtering. I don't want the grid to preload all of the data and then filter. I want it only to load based on the dropdown. But when I set it up the way I think it should work it is calling my controller method twice. The first time passing the parameter correctly from the dropdown and the second time passing a null.

Here is the view:

<div class="filter">

<label class="filter-label" for="filter">Filter:</label>

@(Html.Kendo().DropDownList()

.Name("filter")

.DataTextField("Text")

.DataValueField("Value")

.Events(e => e.Change("onChange"))

.BindTo(new List<SelectListItem>() {

new SelectListItem() {

Text = "Pending Reviews",

Value = "N"

},

new SelectListItem() {

Text = "Complete Reviews",

Value = "Y"

}

})

)

</div>

<br class="clear" />

<br />

@(Html.Kendo().Grid<PASSAdmin.ViewModels.ResourceReviewer.ResourceReviewViewModel>()

.Name("gridResourceReviews")

.Columns(columns =>

{

columns.Command(command => { command.Edit(); }).Width(50);

columns.Bound(m => m.Proposal_ID).Title("Proposal ID");

columns.Bound(m => m.Proposal_Title).Title("Title");

columns.Bound(m => m.PI_BNL_ID).Title("PI");

columns.Bound(m => m.Date_Submitted).Title("Date Submitted");

})

.Editable(editable => editable.Mode(GridEditMode.PopUp).TemplateName("ResourceReviewer/ResourceReview").Window(window => window.Width(700)))

.Pageable()

.Sortable()

.Events(e => e.Edit("onEdit"))

.DataSource(dataSource => dataSource

.Server()

.Model(model =>

{

model.Id(m => m.Beamtime_Request_ID);

model.Field(m => m.Beamline_Request_ID);

})

.Read(read => read.Action("GetResourceReviews", "ResourceReviewer"))

.Update(update => update.Action("AddResourceReview", "ResourceReviewer"))

))

<script type="text/javascript">

function onEdit(e) {

$(e.container).parent().css({

width: '700px',

height: '350px'

});

$(e.container.find(".k-edit-buttons.k-state-default")).css("width", "660px");

}

function onChange() {

var filter = this.value();

alert(filter);

$.get('/ResourceReviewer/GetResourceReviews', { reviewComplete: filter }, function (data) {

var grid = $("#gridResourceReviews").data("kendoGrid");

grid.dataSource.read();

});

}

</script>

And here is the controller method:

public ActionResult GetResourceReviews(string reviewComplete, [DataSourceRequest]DataSourceRequest request)

{

User user = new User();

int user_id = user.GetUserIDByBNLAccount(User.Identity.Name);

int resource_id = UserSession.LastViewedResourceID.GetValueOrDefault();

if (UserPermissions.VerifyResourceRole(user_id, resource_id, "Resource_Reviewer"))

{

using (PASSEntities context = new PASSEntities())

{

var vm = (from a in context.Beamtime_Requests

join b in context.Proposals on a.Proposal_ID equals b.ID

join c in context.Technique_Requests on a.ID equals c.Beamtime_Request_ID

join d in context.Beamline_Requests on c.ID equals d.Technique_Request_ID

join e in context.Beamlines on d.Beamline_ID equals e.ID

join f in context.Users on b.PI_User_ID equals f.ID

where a.Status == "BLREV" && d.Beamline_ID == resource_id && d.Beamline_Review_Complete == reviewComplete

select new ResourceReviewViewModel()

{

Date_Submitted = a.Date_Submitted,

Beamline_Request_ID = d.ID,

Beamtime_Request_ID = a.ID,

Proposal_ID = b.ID,

Proposal_Type_ID = b.Proposal_Type_ID,

Beamline_Review_Complete = d.Beamline_Review_Complete,

Current_Cycle_Request = a.Current_Cycle_Request,

PI_User_ID = b.PI_User_ID,

PI_BNL_ID = b.User.BNL_ID,

Proposal_Title = b.Title,

Refused_By_Beamline = d.Refused_By_Beamline

}).ToList();

DataSourceResult result = vm.ToDataSourceResult(request);

return Json(result, JsonRequestBehavior.AllowGet);

}

else

{

return RedirectToAction("Index");

}

Changing the ContentType in the http request

Hello,

I am looking for a way to change the contenttype in the http request, it seems you can do it in jquery but there doesn't seem to be a way to do it with the razor html helpers. I would think it would work something like line #6. Is this possible?

Thanks,

01..DataSource(dataSource => dataSource

02. .Ajax()

03. .PageSize(20)

04. .ServerOperation(true)

05. .Events(events => events.Error("error_handler"))y

06. .Create(update => update.Action("Customer_Create", "Customer", ContentType="Application/Json")

07.

08. )

09. .Read(read => read.Action("Customer_Read", "Customer"))

10. .Update(update => update.Action("Customer_Update", "Customer"))

11. .Destroy(update => update.Action("Customer_Delete", "Customer"))

12. .

BindTo After Read Action

Hello.
I have a scheduler and an EditorTemplate.
I want to bind a multiselectfor after the reading method. (with my Model which is populated in the read Method).
I suppose the .BindTo() Display nothing because the read method 'll be call after this one.

So here is my scheduler :

@(Html.Kendo().Scheduler<iMail.Web.Models.TaskViewModel>()

.Name("scheduler")

.Date(DateTime.Now)

.Timezone("Etc/UTC")

.Views(views =>

{

views.DayView();

views.WeekView();

views.MonthView();

views.AgendaView(agenda => agenda.Selected(true));

})

.Selectable(true)

.Timezone("Etc/UTC")

.Events(e =>

{

e.Edit("onEdit");

e.Change("onChange");

})

.Editable(editable =>

{

editable.TemplateName("_EditorTemplatePartial");

})

.DataSource(d => d

.Model(m =>

{

m.Id(f => f.TaskID);

m.Field(f => f.Title).DefaultValue("No title");

m.RecurrenceId(f => f.RecurrenceID);

m.Field(f => f.Priority);

m.Field(f => f.TypeID);

})

.Events(e => e.Error("error_handler"))

.Read (read => read.Action("TasksRead", "Calendar").Data("additionalInfo").Type(HttpVerbs.Get))

.Create(create => create.Action("TasksCreate", "Calendar").Data("additionalInfo"))

.Destroy(destroy => destroy.Action("TasksDestroy", "Calendar").Data("additionalInfo"))

.Update(update => update.Action("TasksUpdate", "Calendar").Data("additionalInfo"))

)

And here is my MultiSelectFor in the _EditorTemplatePartial.cs file.

<div id="AttendeeAlreadyInvited">

<div data-container-for="AlreadyInvitedID" class="k-edit-field">

@(Html.Kendo().MultiSelectFor(model => model.AlreadyInvitedID)

.HtmlAttributes(new { data_bind = "value:AlreadyInvitedID" })

.DataTextField("Name")

.DataValueField("ID")

.BindTo(Model.Invited)

)

</div>

Model.Invited has a structure like this :

public class CalEmployeeLight

{

public int ID;

public string Name;
}

Here is a part of my model :

public class TaskViewModel : Kendo.Mvc.UI.ISchedulerEvent

{

   public int TaskID { get; set; } //each event have an ID.

   .....

   public IEnumerable<

int> AlreadyInvitedID { get; set; }

public ICollection<CalEmployeeLight

> Invited { get; set; }

}

Each event in the Scheduler have an ID (TaskID)

The Model is populated in the TaskRead fct and works correctly.
But my multiselectFor is empty.

How can i use .bindTo() fct in the MultiSelectFor() after the Model is populated by "TaskRead" ?

Kendo Ui - Dependency Injection

Hi,

I'm currently developing an application with the support of Windsor Castle (DI container).

As I also want to use Kendo in this project, I started with a simple Grid.

Suddenly the Exception "no parameterless constructor defined for this object" came up.

I've found some threads about this on the net - like this one (http://www.telerik.com/forums/binding-to-an-arraylist-4539b158237a) - which are talking about the same error.
But the solution suggested in those are not satisfying, because I don't want to introduce a parameterless constructor if I don't need one (beside of Kendo).

Is there a way to use Kendo without having parameterless constructors?

Thanks in advance.

Kind regards
Daniel
