Hello,

I have some trouble to get the data bind of a list in a EditorTemplate for the schelduler.

Here is how i create the schelduler :

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

.Name("scheduler")

.Date(DateTime.Now)

.StartTime(new DateTime(2013, 6, 13, 7, 00, 00))

.Height(600)

.Views(views =>

{

views.DayView();

views.WeekView();

views.MonthView();

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

})

.Selectable(true)

.Timezone("Etc/UTC")

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

.Editable(editable => {

editable.TemplateName("_EditorTemplatePartial");

editable.Resize(true);

})

.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(e => e.Attendees).DefaultValue(new List<iMail.Web.Models.CalendarAttendeeModel>());

})

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

.Read("TasksRead", "Dashboard")

.Create("TasksCreate", "Dashboard")

.Destroy("TasksDestroy", "Dashboard")

.Update("TasksUpdate", "Dashboard")

)

Code of _EditorTemplatePartial.cs

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

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

.Name("myMultiSelectiHATEYOU")

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

.DataTextField("AttendeeName")

.DataValueField("ID")

.BindTo(ViewBag.Contacts)

.Value(Model.Attendees)

</div>

Here is the data load in the MultiSelect

ICollection<CalendarAttendeeModel> contacts = new List<CalendarAttendeeModel>();

CalendarAttendeeModel att7 = new CalendarAttendeeModel();

att7.AttendeeName = "Georgette";

att7.ID = 4;

att7.Email = "myemail@attendee7.com";
........

contacts.Add(att7);

contacts.Add(att8);

contacts.Add(att9);

contacts.Add(att10);

ViewBag.Contacts = contacts;

The data in the multislect seems to be correctly loaded but when i want to save the data inside of TasksCreate() i have some trouble with my list.
Sample : If i select 4 item, my list count 4 row but haven't any data inside.
Moreover i can't try to use a datasource because of this template ".Editable(editable => { editable.TemplateName("_EditorTemplatePartial");"

public ActionResult TasksCreate([Kendo.Mvc.UI.DataSourceRequest]Kendo.Mvc.UI.DataSourceRequest request, TaskViewModel task)

{

}

My CalendarAttendeeModel is a List inside of the model TaskViewModel

public class TaskViewModel : Kendo.Mvc.UI.ISchedulerEvent

{

....

public string Title { get; set; }

public string Description { get; set; }

public string StartTimezone { get; set; }

public string EndTimezone { get; set; }

....

public List<CalendarAttendeeModel> Attendees { get; set; }

}

I can't get the selected data in the list inside of the editor template.
In the TasksCreate i can get the data of Description,... (it's the user who write the data) but for the List, i have a big problem.

I use Kendo UI 2013.3.1511 and Razor engine.

I'm stuck with that :/
Any idea to suceed ?

Refresh KendoUI TreeView after AJAX update

Hello -

I have the following TreeView in my application:

@(Html.Kendo().TreeView()
.Name("treeview")
.ExpandAll(true)
.Events(events => events.Select("onTreeNodeSelected"))
.BindTo((IEnumerable<TreeViewItemModel>)ViewBag.NavigationTree))

I have a button on the page that when clicked a KendoWindow gets displayed and allows the user to enter in text for a new node. On the submit button within the KendoWindow it posts the AJAX form and the ViewBag.NavigationTree gets updated.

How can I have the new node be added to the tree via AJAX? Essentially I want to update the TreeView's BindTo when the ViewBag.NavigationTree gets updated via an AJAX call.

Thanks in advance,
Dan

Treeview Node Id passing to Controller action

Hi,

I'm trying to redirect to a controller action and pass the ID of the selected tree node into the controller action.

Ideally, I would like to use some code like this:

<div class="kendo-tree">

@(Html.Kendo().TreeView()

.Name("treeview")

.DataTextField("Name")

.TemplateId("treeview-template")

.DataSource(dataSource => dataSource

.Read(read => read.Action("DashboardTree", "Home"))

)

.Events(e => e.Select("onSelect"))

)

</div>

And here's what the onSelect would do:

function onSelect(e) {

var data = $('#treeview').data('kendoTreeView').dataItem(e.node);

//alert("node clicked" + data.id);

window.location = @Url.Action("Edit", "Employee", new { id = data.id });

}

I'm not sure if window.location is the way to do this and would welcome better suggestions. I don't have a form to submit, I just want to go to another page when the user clicks a tree node. Surely I'm missing something here...

Thanks,
bh

Set focus after click event

I have a Kendo button with the click event defined as:

@(Html.Kendo().Button()
.Name("btnAddNewLineItem")
.Tag("span")
.Icon("plus")
.Content(@InvSubModule.Infrastructure.Localization.ResourceManager.GetString("AddNew") +" " + "<span></span>")
.HtmlAttributes( new {type = "button"} )
.Events(ev => ev.Click("AddLineItemButtonRequest"))
)

In my JavaScript method: "AddLineItemButtonRequest", the last line sets the focus to another control on the page via jQuery:

$("#LineItemType").focus();

However, after this line, the focus is shifted back to the Kendo button above. Is there another way I should be setting the focus?

Thanks for your time,
Scott Dulock

Annotating editable, causing grid to fail

What I am trying to do.. is create this grid of CartLines, display them, and allow editing of ONLY the quantity field.
This grid below displays, and is editable (presumably, I haven't implemented the update action but the UI appears to work).

The moment I added .Editable(false) to any of the model.Fields, I get an error that the object is not referring an object ..

>> Object reference not set to an instance of an object.

and that happens before it even tries to call the read action. And I am quite surprised about the behavior on the first column, the picture column. That field is editable also which surprised me. I mean.. I guess i didn't tell it not to.. But it is clearly associating it with the modeId and I would think the modelid is sacred and shouldn't be changed.

Anyway... what's the best way to accomplish this?
Quantity should be editable
Nothing else should be editable.
(though I may add a delete the entire row option)

@(Html.Kendo().Grid<EveShop.Domain.Entities.CartLine>()

.Name("cartGrid")

.DataSource(

dataSource => dataSource

.Ajax()

.Read(read => read.Action("GetCartList", "Cart").Data("additionalCartListData"))

.Model(model =>

model.Id(p => p.Product.ProductID);

model.Field(p => p.Product.Name);

model.Field(p => p.Quantity);

model.Field(p => p.Product.Price)/*.Editable(false)*/;

})

)

.Columns(columns =>

{

        // this first column is really just a picture column, may be a better way to do this

        // than binding it to Product.ProductID?  to an empty field?  didn't see how to do that.

      c

olumns.Bound(line => line.Product.ProductID).ClientTemplate("<img src='" + Url.Content("~/Images/Types/") + "#:Product.ProductID#_64.png' alt='#: Product.ProductID #' />").Title("Picture");

columns.Bound(line => line.Product.Name);

columns.Bound(line => line.Quantity);

columns.Bound(line => line.Product.Price);

})

.Editable(editable => editable.Mode(GridEditMode.InCell))

)

Always Display Group Message

I am using the grouping function of the Grid. I would like to display the "Drag a column header and drop it here to group by that column" message always, not just when there is no grouping, because I have one column that is grouped by default when the page loads, and the user still needs to know how it works. Is there a way to have this message displayed always?

Set selected item in ddl using ajax binding with value from model

I have a popup window to be used for editing detailed information of a row in a grid. The popup window's content is from a partial view. In this popup window I have a dropdownlist for states. This custom popup edit window is opened when a custom command button is clicked. I call an action on the controller to pull the data to populate the custom popup, I put that data in a model and I have the custom popup using the model. Everything works fine, except the dropdownlist's selected value is not set. It just shows the first item in the list. I've tried setting the .Value option to the model value - .Value(Model.state) - doesn't work. I've tried using the DataBound event to set the value there to the model.State, but I get errors. If I try to declare the event function in the popup partial view, it doesn't get recognized and I get the not declared error. If I try to declare it in the calling view, it doesn't recognize the model (since it's in the partial view). What am I doing wrong? Any help is very much appreciated!

Here's the code:

Calling view (Index.cshtml) - grid and popup window:

@model IEnumerable<GMCEventRegistrationTools.Models.EventRegistrationModel>

@(Html.Kendo().Grid<GMCEventRegistrationTools.Models.EventRegistrationModel>()

.Name("EventRegistrationGrid")

.AutoBind(false)

.ToolBar(toolbar => toolbar.Create())

.Editable(editable => editable.Mode(GridEditMode.InLine))

.DataSource(dataSource => dataSource

.Ajax()

.Model(model => model.Id(p => p.RegistrationKey))

.Read(read => read.Action("Registrants_Read", "Home").Data("registrantsForEvent"))

.Create(update => update.Action("EditingPopup_Create", "Home"))

.Update(update => update.Action("EditingPopup_Update", "Home"))

.Destroy(update => update.Action("EditingPopup_Destroy", "Home"))

)

.Columns(cols =>

{

cols.Bound(p => p.RegistrationKey).Hidden(true);

cols.Bound(p => p.FirstName);

cols.Bound(p => p.LastName);

cols.Bound(p => p.CompanyName);

cols.Bound(p => p.ProvideAccomodations);

cols.Bound(p => p.RegistrationConfirmed);

cols.Command(command => { command.Edit(); command.Destroy(); });

cols.Command(command => command.Custom("Edit Details").Click("editDetails"));

}

)

.ClientDetailTemplateId("registration-client-template")

)

@(Html.Kendo().Window().Name("EditRegDetails")

.Title("Edit Registration")

.Visible(false)

.Modal(true)

.Draggable(true)

.Width(900)

)

function editDetails(e) {

e.preventDefault();

var dataItem = this.dataItem($(e.currentTarget).closest("tr"));

var window = $("#EditRegDetails").data("kendoWindow");

window.refresh({

url: '/Home/GetRegistrationDetails',

data: { id: dataItem.RegistrationKey }

});

window.center();

window.open();

}

Controller/Action:

public ActionResult GetRegistrationDetails(int id)

{

EventRegistrationModel eRegistrationModel = new EventRegistrationModel();

using (var eventTools = new WebDBEntities())

{

WebEventRegistration reg = eventTools.WebEventRegistrations.Where(p => p.RegistrationKey == id).FirstOrDefault();

AdditionalInfo ai = new AdditionalInfo();

var serializer = new JavaScriptSerializer();

if (reg != null && (reg.FirstName != null && reg.FirstName != ""))

{

eRegistrationModel.AddressLine1 = reg.AddressLine1;

eRegistrationModel.AddressLine2 = reg.AddressLine2;

eRegistrationModel.City = reg.City;

eRegistrationModel.CompanyName = reg.CompanyName;

eRegistrationModel.EmailAddress = reg.EmailAddress;

eRegistrationModel.EventDetails = serializer.Deserialize<AdditionalInfo>(reg.EventDetails);

eRegistrationModel.EventName = reg.EventName;

eRegistrationModel.FirstName = reg.FirstName;

eRegistrationModel.JobTitle = reg.JobTitle;

eRegistrationModel.LastName = reg.LastName;

eRegistrationModel.MiddileInitial = reg.MiddileInitial;

eRegistrationModel.PhoneNumber = reg.PhoneNumber;

eRegistrationModel.PostalCode = reg.PostalCode;

eRegistrationModel.ProvideAccomodations = reg.ProvideAccomodations == 0 ? true : false;

eRegistrationModel.ReferrerIpAddress = reg.ReferrerIpAddress;

eRegistrationModel.RegistrationConfirmed = reg.RegistrationConfirmed == 0 ? true : false;

eRegistrationModel.RegistrationDate = reg.RegistrationDate;

eRegistrationModel.State = reg.State;

eRegistrationModel.RegistrationKey = reg.RegistrationKey;

}

else

{

return View("Error");

}

return PartialView("EditRegistrationDetails", eRegistrationModel);

}

Partial view with dropdown:

@model GMCEventRegistrationTools.Models.EventRegistrationModel

@using (Html.BeginForm("SaveRegistrationEdit", "Home", FormMethod.Post, new { id = "editregis-form" }))

{

most fields removed for brevity

<div class="form-group">

@Html.LabelFor(model => model.State)

@(Html.Kendo().DropDownListFor(model => model.State).Name("State")

.HtmlAttributes(new { @class = "form-control textbox-size stateslist"})

.DataTextField("State").DataValueField("StateCode")

.DataSource(source => {

source.Read(read =>

{

read.Action("GetStates", "Home");

});

})

.Value(Model.State)

.Events(events => events.DataBound("setSelectedState"))

)

<p class="error">@Html.ValidationMessageFor(model => model.State)</p>

</div>

Thanks!

Custom commands at a group level

Hi,

I've just purchased the ASP.Net MVC Kendo UI Grid and I am looking to do the following:-

I have a dataset which in the redacted code below is grouped by RegionalManager like this:-

.DataSource(dataSource => dataSource
.Ajax()
.Group(grp => grp.Add(m => m.RegionalManager ))
.ServerOperation(false)
.Batch(true) // enable batch updates

What I would like to be able to do is somehow add a command at the group level so I could swap the regional manager for an entire grouping.
At the moment, I am only able to add custom commands at the whole grid or row level.

Any help would be much appreciated.

ASP.NET MVC Grid - second page doesn't get properly rendered, instead JSON is displayed

I'm evaluation the Telerik ASP.NET MVC UI components and I'm trying to come to grips with the KendoUI Grid for ASP.NET MVC 3. The initial setup works fine, the first page of data is being displayed just fine....

but when I try to go to the second page, my defined function for the Ajax paging does get called just fine, but instead of the page and the grid with the second set of data, I'm seeing a huge blob of JSON data on my screen......

Must have missed something really basic - but I can't seem to find *WHAT* ! The docs aren't really helping - it seems I'm doing everything as prescribed - but it just doesn't work..... no error message or exception or anything - just throws a blob of JSON at me instead of *rendering* it!

Any ideas? What am I missing?
