Questions on Kendo UI for jQuery Forum

I created my whole page as an SPA, all the links do Ajax calls and just refresh content areas. I have serious performance Issues with content areas that have Kendo widgets. With a lot of subsequent calls the app becomes slower and slower until it freezes. I checked whats happening and I see Kendo with each initalization adds <div> items to the bottom of the <body>, when my app changes the content area which is inside the body these divs stay and with each click they keep growing until they turn into a monster that kills the performance.

Is there some generic method to clean these up?

Datasource vs Mvvm

Trying to wrap my head around the different data access methods. I have read all the docs on datasouce and mvvm but still am a little confused. I know mvvm is a pattern but its not just code seperation as in the examples mvvm is used for dataaccess without using a datasource.

Are datasource and mvvm two different approaches to working with data?
So you could use a datasource and templating for method 1
or Mvvm for method 2

I have read a forum where someone asked about using a datasource with mvvm why would you want to?

A datasource contains part of mvvm because it has the model as part of itself.

Just trying to pick one method for development and stick with it but not sure which one to go with.

Also in Mvvm you have all the different binding methods that are a bit confusing such as html element binding or attribute binding are these to different approaches where you just need to pick either html or attribute?

Thanks,

Dan

Cancel the Request to fill the grid

Hello guys,

I would like to know, if is there any way to cancel the request that fill some data by ajax on the grid of Kendo UI web?

I mean it because I have a page where the user can change the filter (on links.. not on the grid) and sometimes I have a lot of data coming from the async request, so if my user change these filters I would like to cancel the async request and start another one.

Look my code:

var path = 'my-url';
var grid = $("#grid").kendoGridTranslated({
dataSource: {
type: "json",
transport: {
read: {
dataType: "json",
url: path,
cache: false,
type: 'POST',
data: {
parameter: true
}
}
}
/* configuration and fields*/
}).data("kendoGrid");

Thank you.

Example for using Kendo Globalization?

Hi,

we are evaluation Kendo UI. What we like about it is it's support for Globalization using Cultures. But I've got a question about that:
-> Do you have an example how to use the Kendo Globalization in an app?

We would like to be able to use Kendo Globalization for all labels. Is that possible?

Otherwise what do you suggest on that topic? Another possiblity is to use https://github.com/SlexAxton/messageformat.js.

Thanks,
Jan

Hierarchy - customizing the hierarchy cell image based on condition

I have a simple grid with hierarchy data. The thing is, not all records have a data subset, so I don't want to show the hierarchy image for those rows (since there isn't anything to expand). Can anyone think of a way to handle this? Any thoughts on having a custom image for the "expand" link based on a value in the row?

Thanks!

local DataSource getting an error when binding.

This jsFiddle example is a slimmed down copy/paste from the MVVM RemoteBinding demo :

http://jsfiddle.net/rally25rs/WuQwn/

When I run this code, I receive the error "k.push is not a function", and the binding fails. If I remove the DataSource, and instead make viewModel.productsSource = [ ... ] (so it is just an array, not a data source) then the binding works. It only seems to fail when I use a dataSource, but that is what the demo does.

Can someone point out what I am doing wrong?
Thanks for any help.

Switch iOS native styling

Hi!
In the another forum thread you post me a fiddle with a switch example, this one:
http://jsfiddle.net/7WVqL/138/

It looks great and native on my iPad (with rounded corners), exactly as iPad native switch.

But in my project and actually also in your examples here http://demos.kendoui.com/mobile/switch/index.html on iPad the switch looks not native (square corners), actually like in Chrome on Windows PC.

I can not figure out, how to make iPad native like in fiddle I posted here.

PS: please to see difference, open links I posted here on ipad or simulator.
