Datetime in Kendo UI grid: dates before 1970 c#

Has anyone experienced seeing "NaN/NaN/0NaN" in Kendo UI grids for fields prior to 1970? I'm experiencing this in the Kendo UI grids, but not the previous Telerik UI grids.
The fields (date of births) are of type "Datetime?"
The view i'm using uses .Format("{0:d}") for formatting, might that be the issue?

columns.Bound(od => od.PatientDOB).Format("{0:d}").Title("PatientDOB").Width(50);

Attached 2 screenshots for visual representation.
I'm wondering if there is a workaround to this issue.

Any help is greatly appreciated.
Thanks!

[Solved] Dropdown menu in grid rows

Hi guys,

I'm trying to embed a dropdown menu (bootstrap) inside a grid on the first column of each bound row (basically creating a menu for each item). It works but the menu is hidden behind the next row down so there's something to do with the markup of the grid overlapping the markup of the menu.

Here's the markup:

@(Html.Kendo().Grid<Listing>()

.Name("grid")

.DataSource(dataSource => dataSource

.Ajax()

.Read(read => read.Action("RefreshTable", "HomeController"))

)

.Columns(columns =>

{

columns.Bound(x => x.Number)

.Width(120)

.Template(@<text></text>)

.ClientTemplate(

"<div class='btn-group'>" +

"<button type='button' class='btn btn-default btn-sm dropdown-toggle' data-toggle='dropdown'><span id='selectedTagType'>#= Number#</span> <span class='caret'></span></button>" +

"<ul class='dropdown-menu' role='menu'>" +

"<li><a onclick='editRecord();'></a>Edit</li>" +

"<li><a onclick='activateRecord();'></a>Activate</li>" +

"<li><a onclick='transferRecord();'></a>Transfer</li>" +

"</ul>" +

"</div>"

);

columns.Bound(x => x.TypeDescription);

columns.Bound(x => x.PhoneNumber);

})

)

EditorTemplate for Schelduler

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))

)

[Solved] 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?
