[Solved] For create large Web Applications, it's enough with Kendo?

Hi, for create Large Web Applications, it's enough with Kendo, MVVM, DataSource, Template bindings, etc,

or I need to also use any framework like Backbone or Knockout, Ember, or other?

What do You think about this?

Thanks.

Changing data in list from different endpoint

Bottom line: How do I load items in a dropdown list from a different url after it's been initialized?

I have a 3 dropdown lists that are bound to 3 kendo data sources which read json from 3 different endpoints. I want to be able to select something from the first dropdown, and have the second and third dropdowns change. Just as an example, if the first dropdown is names of grandfathers, second dropdown is list of fathers and third dropdown is a list of sons, the third dropdown should only list sons related to the selected father, and the second dropdown should only list fathers related to the selected grandfather.

Cascading dropdowns aren't useful because I'm graphing data about grandfathers, fathers, and sons regardless of their relationships.

The endpoints are:

"service/getGrandfatherList/"
"service/getFatherList/grandfatherID"
"service/getSonList/fatherID"

Problem is, I can't get the second and third dropdowns to change. In my onclose event handler I've tried:

$("fathers").data("kendoDropDownList").dataSource.read(); as suggested in this thread
Re-initializing the dropdown list, though that makes it disappear (see thread linked above)
Assigning the kendo data source to a new kendo.data.DataSource that reads from the appropriate URL then calling datasource.read(), datasource.fetch(),dropdownlist.refresh()

Those do nothing. What's weird is that even after assigning the data source to a new datasource and calling fetch(), it reads from the old url instead of the new one.

Hope I've explained this properly... any ideas?

Javascript Error in Grid

Running Kendo UI 2012.2.710.340 in a MVC 4 .NET Web App.

MVC Grid EditorTemplateName

When using editor templates by name like:

columns.Bound(x => x.Name).EditorTemplateName("String").Width(300);

Causes this to be rendered:

{"title":"Name","width":"300px","field":"Name","encoded":true,"editor":"%3cinput class=\"text-box single-line\" data-val=\"true\" data-val-required=\"Please provide a setting name.\" id=\"Name\" name=\"Name\" type=\"text\" value=\"\" /%3e%3cspan class=\"field-validation-valid\" data-valmsg-for=\"Name\" data-valmsg-replace=\"true\"%3e%3c/span%3e"}

Which then causes the grid, when inline editing to show the html encoded rather than endering the actual html it represents. I see an "encoded:true" but it doesn't seem to be treating the editor as encoded.

Thanks in advance.

EDIT: I blogged a workaround.

ASP.NET MVC 4 Partial View templates - invalid template issue.

I am wondering if there is any sample code / API that can process the output after calling HtmlHelper.Partial(...). In many cases, we use the same partial view to render the repeating items and also the template for when the user adds new items at the client. The '#' character is the trouble. In many cases a # character is used in an <a href='#'... or else where which is not part of the template. Recently, I just used the following code to get around the href='#' issue,

var template = html.Partial(...);
string str = template.ToHtmlString();

str = str.Replace("href=\"#\"", "href=\"\\\\#\"");
str = str.Replace("href='#'", "href='\\\\#'");

return new MvcHtmlString(str);

it would be great if someone had a regex or a helper function that could escape all the non-template '#' characters. I would really be unfortunate if I have to duplicate all my partial views just make them template safe.

How to bind Grid to Web API Controller?

I'm having trouble binding data from a Web API Controller to a Grid. Unfortunately I haven't been able to find any examples of this.

Here's the API Controller:

public class FruitController : ApiController

{

public class Fruit

{

public string Name { get; set; }

public string Color { get; set; }

}

public IEnumerable<Fruit> GetFruits()

{

List<Fruit> list = new List<Fruit>();

Fruit f = new Fruit();

f.Name = "Apple";

f.Color = "Red";

list.Add(f);

f = new Fruit();

f.Name = "Kiwi";

f.Color = "Green";

list.Add(f);

return list;

}

And in my .cshtml file I have:

@model IEnumerable<FruitController.Fruit>

@(Html.Kendo().Grid(Model)

.Name("Grid")

.Columns(columns =>

{

columns.Bound(p => p.Name);

columns.Bound(p => p.Color);

})

.Groupable()

.Pageable()

.Sortable()

.Scrollable()

.Filterable()

.DataSource(dataSource => dataSource

.Ajax()

.Read(read => read.Action("GetFruits", "api/Fruit").Type(HttpVerbs.Get)

)

When I run this, I get a successful JSON response from the controller (seen via Chrome):

[{"Name":"Apple","Color":"Red"},{"Name":"Kiwi","Color":"Green"}]

But the grid has no data in it. Is there something obvious I am missing? I haven't been able to figure this out!

Thanks!

[Solved] Error on validating field if id starts with 'first' or 'last' (jQuery 1.8.0)

Dear Developers,

there is a bug in _validate method of the Editable widget. There is a line in the code (ln. 30578, kendo.web.js v2012.2.710) which tries to retrieve the input element:

input = $(':input[' + kendo.attr("bind") + '="' + (isBoolean ? 'checked:' : 'value:') + e.field + '"]', that.element);

If the field's name starts with 'first' or 'last' (e.g. first_name) the computed selector will be:

':input[data-bind="value:first_name"]'

In that case jQuery 1.8.0 can not find the element because the css parser throws an exception:

Uncaught Error: Syntax error, unrecognized expression: :input[data-bind="value

Obviously with jQuery 1.7.1 there is no exception.
This may be unconfortable in the future.
