Validation call not triggered on grid column sort / filter

Validation used for a field in KendoGrid works fine on currently being edited cell when I try to select other cell.But It doesn't work when I try to sort any column or use filter. Is it possible to prohibit user from sorting or filtering till validation for the field passes.

Code used for validation in datasource for one of field.

01.Project:{

02.editable:true,

03.validation: {

04.custom: function(input) {

05.if(input.val()=="") {

06.input.attr("data-custom-msg", "Message");

07.return false;

08.}

09.else

10.return true;

11.}

12.}

13.}

programmatically select a value in dropdown

Hi

I want to store selected item state. I can't trigger 'select' event properly.

$('#groups').kendoDropDownList({

dataSource: [

{ text: "No group", value: "none" },

{ text: "By type", value: "type_label" },

{ text: "By route", value: "route_label" },

{ text: "By status", value: "status_label" }

],

dataTextField: "text",

dataValueField: "value",

select: function(e){

var selectedDataItem = this.dataItem(e.item.index());

set_global_setting ("group_state", dataItem.value);

// ... code which depends on selectedDataItem and works this.dataSource

}

}).data("kendoDropDownList").select(function(dataItem){

return dataItem.value === get_global_setting("group_state");

});

var groups_dropdown = $('#groups').data("kendoDropDownList");

groups_dropdown.trigger("select", {item : groups_dropdown.dataItem()}); // does not work since 'select' event expects 'e.item' as 'li'

When user changes selected value 'e.item' in 'select' event is a 'li'.
When I change selected value programmaticlly I should specify next selected item not as dataItem but as 'li'.
How can I do this?
Maybe I should somehow change 'selectedDataItem' definition in 'select' event?

Cascading List Views with knockout

Hi,

I have an viewmodel with an observable array of objects, and a computed selectedObject. I'm attempting to bind a KendoListView to an observable array in selectedObject, but the ListView doesn't get updated.

There's a fiddle demonstrating the issue here:

http://jsfiddle.net/JrJ2q/3/

I'd appreciate any support you could provide.

Thanks,

Sorting on Custom Edit Column

Hello,

I am having a problem sorting by the column that I enabled a custom editor for.

I basically followed the sample at http://demos.kendoui.com/web/grid/editing-custom.html

How would you go about sorting by the "Category" column? The column it self is an object, so I think is getting confused.

Any ideas?

Thanks!

Multiselect not rendering correctly, throbber always showing, lookups appearing above text field

This is for Kendo UI version 2013.1.514.340.

Here is my MVC view:

<script src="~/Scripts/jquery-1.7.1.js"></script>
<script src="~/Scripts/kendo.web.min.js"></script>
<script src="~/Scripts/kendo.aspnetmvc.min.js"></script>
<link href="~/Styles/examples.css" rel="stylesheet" />
<link href="~/Styles/kendo.common.min.css" rel="stylesheet" />
<link href="~/Styles/kendo.default.min.css" rel="stylesheet" />

@using Kendo.Mvc.UI
@model List<CV.Prototype.ViewModels.MyRecord>

@(Html.Kendo().MultiSelect()
      .Name("categoryMultiselect")
      .DataTextField("Name")
      .DataValueField("Id")
      //SERVER BINDING
          .BindTo(Model)
          .Value(Model)
      )

My controller is simply:
        public ActionResult Index()
        {

            var x = new List<MyRecord>
                {
                    new MyRecord {Id = 1, Name = "Name1"},
                    new MyRecord {Id = 2, Name = "Name2"},
                    new MyRecord {Id = 3, Name = "Name3"},
                    new MyRecord {Id = 4, Name = "Name4"}
                };
            return View(x);
        }

All the records display inside the grey boxes, but are not inside the input text box. Also the throbber is constantly displaying. Apart from this it functions correctly both with Server and Ajax binding. Any clues as to what I might be missing?

DropDownList Remnants on View Change

Hi,

I'm not sure if this is a bug or just a misunderstanding on my part. I'm also putting this post here, but it may be more relevant for the SPA section!

When using a dropdownlist inside a view (rendered as part of an SPA layout), the following element is created at the foot of the body (as well as the normal markup):

<div style="display: none; position: absolute;" data-role="popup" id="dropdownlist1-list" class="k-list-container k-popup k-group k-reset"><ul aria-live="off" id="dropdownlist1_listbox" aria-hidden="true" role="listbox" tabindex="-1" style="overflow: auto;" unselectable="on" class="k-list k-reset">

On a view change, using layout.showIn(), I was to understand the the view and all its child elements would be removed from the DOM. As it is, these elements remain - if the view reference is retained it would appear that only one instance is created if the the view reference is recreated, a duplicate is formed when the view is rendered.

The JSFiddle here demonstrates the issue hopefully. Obviously if there are a lot of views being used with many dropdownlists, then the capacity for many of these remnants to be created could be significant. I haven't done exhaustive testing, but this doesn't seem to happen for (for example) the grid.

Grateful for any assistance!

Many thanks,

J.

mismatched quotation marks around the word groupable in kendo.all.min.js

Not sure what version of kendo I have, but the javascript parser add-in for Visual Studio detected an anomaly in the kendo.all.min.js file -- in one place the word groupable is quoted with a single quote on the left end and a double quote on the right end.

mismatched quotation marks 'groupable" in kendo.all.min.js

I'm not sure what version I've got, but there's a mismatched quotation mark (single on one end , double on the other) in kendo.all.min.js.

I tried to attach a PNG showing where it is, but there's an error message "Invalid post content".

Thanks

GridEditMode.InLine after Edit then Update - Grid Stays In Edit Mode

Title says it all. I am editing a record inline. When I hit update, the request to the server occurs, the record is saved and the response is returned. However, the Grid does not acknowledge the fact that the AJAX request was successful. So the Grid stays in edit-mode. If I cancel then refresh the grid, the row shows up as it should (saved). No errors are occurring on the server or client.

I'm using the ASP.NET MVC Wrappers - AJAX.

<div style="width: 700px">

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

.Name("grdRoles")

.Columns(columns =>

{

columns.Bound(r => r.Name).Width(200);

columns.Bound(r => r.Description).Width(300);

columns.Command(command => {

if (security.CanAdd || security.CanUpdate) command.Edit();

if (security.CanDelete) command.Destroy();

}).Width(200);

})

.Groupable(grouping => grouping

.Enabled(false))

.Events(events => { if (security.CanAdd && !security.CanUpdate) events.DataBound("function() { this.table.find('.k-grid-edit').hide(); }"); })

.DataSource(dataSource => dataSource

.Ajax()

.Model(model => model.Id(r => r.RoleId))

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

.Read(read => read.Action("Index", "Roles", new { area = "Setup" }))

.Create(create => create.Action("Create", "Roles", new { area = "Setup" }))

.Update(update => update.Action("Edit", "Roles", new { area = "Setup" }))

.Destroy(destroy => destroy.Action("Delete", "Roles", new { area = "Setup" }))

.Sort(sort => sort.Add(r => r.Name).Ascending())

.PageSize(10))

.Filterable(filtering => filtering

.Enabled(true))

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

.Pageable(paging => paging

.Enabled(true)

.Info(true)

.PageSizes(false)

.Refresh(true))

.Scrollable(scrolling => scrolling

.Sortable(sorting => sorting

.Enabled(true)

.AllowUnsort(false)

.SortMode(GridSortMode.SingleColumn))

.ToolBar(toolbar => { if (security.CanAdd) toolbar.Create(); })

)

</div>

[HttpPost]

public ActionResult Edit([DataSourceRequest] DataSourceRequest request, RoleGridModel model)

{

if (ModelState.IsValid && model != null)

{

try

{

Role r = Mapper.Map<RoleGridModel, Role>(model);

r.AppContext = this.AppContext;

r.SubscriberId = this.AppContext.SelectedSubscription.SubscriberId;

r.ModifyDate = DateTime.UtcNow;
