Multi-column menu

Will there be any in-built functionality to support multi-column lists in a menu (ordered correctly)?
How would I go about it? Has anybody else done this to a menu control?

Raw Data with Kendo Upload

Maybe I am doing something wrong or I am missing something, but do I have to provide a save URL or can I just get the bytearray of the file when it is done uploading?

I do not see an event/property/method that will give me access to the data that has been uploaded.

Kendo mobile performance tips

Hi all,
I'm building a Phone gap application running on iPad 3 using Kendo Mobile.
I currently have around 8 views on 1 html. 2 of the views have Kendo DataViz.
Transition across views are set to use slide.
Kendo Mobile controls are defined using data-* markups (instead of programmatically from javascript).
Helper classes, etc. are defined as javascript classes using closures.
There are minimal logic in javascript other than calling webservices with jquery and updating the UI with jquery selector (not MVVM).

As you see above, the app is very simple & small in nature. Yet, I'm having performance issues:

activating Kendo Mobile button requires longer tap. quick tap will trigger button "on down" animation however do not trigger the view redirection (redirection is done using href, not application.navigate)
sliding between view is notably sluggish. for 30-50ms I can see the background of the view rendering on the background. so for that moment, there's a white vertical stripe panning across left to right

Do you see any obvious flaw in the approach above that may cause performance issues?

does splitting views across html help performance?
should I be relying on other view transitions that inherintly lighter?
should I define the Kendo controls programmatically rather using data-*? is there a penalty for having to rely on Kendo scanning the whole dom for data-* attributes?
is there specific best practices for managing memory in javascript in relation to Kendo?

Thanks

Tab Order Feature for Kendo Controls - Section 508 Compliance

Hi,

As per Section 508, a user should be able to navigate through the screen/controls using Keyboard. To achieve this in Asp.Net we have a property exposed to each control namely "Tab Order" which actually signifies the control focus sequence when using the Tab key from the key board.

Is there a provision to have a Tab Order Feature enabled for all the Kendo Controls?

Thanks & Regards,
Manoj Kapoor

Managing Views in Single Page Application

Hi,

In MVVM samples that I've seen so far, I don't see any way to manage Views in an SPA.

Namely, I'm wondering how to "swap" Views in and out according to the user's selection in, let's say, a navigation menu.

Would it be a good idea to use the "visible" binding to show/hide different views ?

Or is there something built into KendoUI to help us manage this ?

I took a quick look at the KendoUI Mobile, and it seems that there is built-in View management, with transitions and all, so could we somehow reuse this for desktop browser based apps ?

Thanks for sharing your ideas.

Need to customize update URL based on row being updated

I need to be able to customize the update URL for each row in my data source. For example, the URL should be /resource/{id}. I read in another thread that it wasn't possible to set this to be a function, so I'm wondering if you could expose an event on the datasource for every row that fires during a sync. This event would pass the row so I could modify the URL on the fly.

Post of values not appearing

Can anyone see what is wrong with this please? I populate a grid. When I edit a row in the grid and choose save changes I have a controller action method being called by the datasource but I get a collection with one empty object - all properties are null or 0.

var datasource = new kendo.data.DataSource({

transport: {

read: {

url: "/AccountDetails/IndexForRequest/" + $("#Request.Id").val(),

dataType: "json",

data: { bankId: $("#BankId").val(), confirmationRequestId: $("Request.Id").val() }

},

update: {

url: "/AccountDetails/EditForRequest",

type: 'POST',

dataType: "json"

},

destroy: {

url: "/AccountDetails/DeleteForRequest",

type: 'POST',

dataType: "json"

},

create: {

url: "/AccountDetails/CreateForRequest",

type: 'POST',

dataType: "json"

}

},

batch: true,

pageSize: 30,

schema: {

model: {

id: "Id",

fields: {

Id: { editable: false, nullable: true },

Client: { editable: false, nullable: true },

Balance: { editable: false, nullable: true, type: "number" },

Currency: { editable: false, nullable: true },

EntityName: { editable: true, nullable: false, validation: { required: true } },

AccountName: { editable: true, nullable: true },

AccountNumber: { editable: true, nullable: false, validation: { required: true } },

SortCode: { editable: true, nullable: false, validation: { required: true } }

}

});

My controller action is...

[HttpPost]

public JsonResult EditForRequest(IList<

AccountDetailDto> models)

{

List<AccountDetailDto> returnObject = GenerateAccountDataForClientA();

return new JsonResult()

{

Data = returnObject,

JsonRequestBehavior = JsonRequestBehavior.AllowGet

};

}

Thanks

[Solved] Treeview Templates documentation

http://demos.kendoui.com/web/treeview/templates.html
looks like it has the same content as the "Basic Usage" documentation page
and thus nothing about templates, even though the "templates"
tab is selected. I'd sure like to see some doc on templates.

While you're at it:
The tip in this forum about {text: "<b>stuff</b>", encode: false}
is too important to leave buried in a forum.
If this is in the main doc, I missed it.
Consider having the default for this to be true, then I wouldn't have to know about it!
Also "encode" doesn't mean much to me.
Instead how about: render_html: true
