Hello, I am building some kind of single page application with Kendo UI controls included on each view;

Navigation between sites is written in javascript with no server page reload (main div container is re-rendering depending on the content via ajax call).

Main view contains Kendo.Window, and looks like this:

My kendo window render function is placed in script file, which starts with the page, when it is "$(document).ready()"; here is the code:



When I open this view for the first time and click the button to open the window - it becomes visible; when I click on "#WindowButton" it shows one alert "button clicked!";


Problem starts, when I go to other view, and back again to this first view (I remind: with no page refresh, it is single page app) - then, when I open the window, and click on "#WindowButton", alert "button clicked!" openes two times - one after the other. When I go to other view and back to this once again (for the 3rd time), it shows 3 times and so on;

I noticed that all kendo controls are rendering on every single view load, and the old ones aren't replaced by new rendered, but they are duplicating, below the code from google chrome developer tools:

First view opened for the first time:



Control is rendered on the 7th line - when I open window, property "display" changes its value from "none" to "block" - it is obvious and correct;

When I open the same view for the second time (without server page reload), my HTML looks like this:


As you can see, kendo window control is rendered two times, so when I call button, placed on a window, the action is called two times :/ (action is recognized by jQuery function when element with id="WindowButton" is clicked - now there are two same buttons with the same ID). When I go to this page 3rd, 4th, 5th and so on, I receive html with as many duplicates of kendo controls as many times I have been opening this view.

Ofcourse it is simplified code above, true code is much, much heavier.


When I click refresh button on my web browser - html shows one kendo window, and all is back set to normal.


What should I do to avoid this problem? Maybe should I manually delete kendo html elements from view "on view detach" in javascript function? Are there any detach functions for kendo UI controls?

I am using a bar chart with stacked series in version v2013.2.726. The user can click on items in the legend to disable or enable them. I would like to determine which items are enabled.

I tried using the following property: kendoChart._sourceSeries[i].visible. But it does not seem to accurately reflect the enabled state of the legend item when in the click event handler.

Is there any way to do this?

Is it possible to disable a scrollview via code? I use one as a selector, but once entry has started, it would be nice to disable it.

I am using WCF Data Service 5.6 to return JSON data:

DATA SERVICE CLASS
public static void InitializeService( DataServiceConfiguration config )
{
    config.SetEntitySetAccessRule( "*", EntitySetRights.AllRead );
    config.SetServiceOperationAccessRule( "*", ServiceOperationRights.All );
    config.DataServiceBehavior.MaxProtocolVersion= DataServiceProtocolVersion.V2;
}
[WebGet]
     public IQueryable<Tournament_Players_Result> Tournament_Players( int tournamentID )
     {
            return this.CurrentDataSource.Tournament_Players( tournamentID ).AsQueryable();
      }

Binding the data to a kendoGrid:

SCRIPT
var playersDataSource = new kendo.data.DataSource({
        type: "odata",
        transport: {
               read: {
                      url: http://localhost:41698/Tournament.svc/Tournament_Players?tournamentID=1,
                      dataType: "json"
                }
         }
});

$(document).ready(function () {
       $("#playersGrid").kendoGrid({
                dataSource: playersDataSource,
         });
});

Getting an error message:
ERROR
{"error":{"code":"","message":{"lang":"en-US","value":"Query options $orderby, $inlinecount, $skip and $top cannot be applied to the requested resource."}}}

Without the type="odata" in DataSource the service returns:
{"d":[{"__metadata":{"type":"TournamentModel.Tournament_Players_Result"},"PlayerID":1,"FirstName":"Tiger","LastName":"Woods","Handicap":null,"StartTime":"\/Date(1365674400000)\/","StartHole":"Mako #1"},{"__metadata":{"type":"TournamentModel.Tournament_Players_Result"},"PlayerID":2,"FirstName":"Adam","LastName":"Scott","Handicap":null,"StartTime":"\/Date(1365674400000)\/","StartHole":"Mako #1"},{"__metadata":{"type":"TournamentModel.Tournament_Players_Result"},"PlayerID":3,"FirstName":"Phil","LastName":"Mickelson","Handicap":null,"StartTime":"\/Date(1365675300000)\/","StartHole":"Mako #1"},{"__metadata":{"type":"TournamentModel.Tournament_Players_Result"},"PlayerID":4,"FirstName":"Henrik","LastName":"Stenson","Handicap":null,"StartTime":"\/Date(1365675300000)\/","StartHole":"Mako #1"},{"__metadata":{"type":"TournamentModel.Tournament_Players_Result"},"PlayerID":5,"FirstName":"Justin","LastName":"Rose","Handicap":null,"StartTime":"\/Date(1365676200000)\/","StartHole":"Hammerhead #1"},{"__metadata":{"type":"TournamentModel.Tournament_Players_Result"},"PlayerID":6,"FirstName":"Rory","LastName":"McIlroy","Handicap":null,"StartTime":"\/Date(1365676200000)\/","StartHole":"Hammerhead #1"}]}

Any help would be welcomed!

Thanks,

Greg.

I did not yet dwelve into the code.
Any provision in the framework to prevent XSS and SQL Injection?
Otherwise, what are recommended best practices?

When I run my application on my Lumia 920 or in Chrome using user agent "Mozilla/5.0 (compatible; MSIE 10.0; Windows Phone 8.0; Trident/6.0; IEMobile/10.0; ARM; Touch; NOKIA; Lumia 920)," all the kendo mobile controls are much too big and the application doesn't work at all (see attached screenshot). 

I've only included kendo.mobile.all.min.js, kendo.mobile.all.min.css, and the entire images file in my solution. Any ideas what might cause this?

I see the same issue when I override the user agent in Chrome on the kendo mobile demos site (http://demos.kendoui.com/mobile/m/index.html) but not on my Lumia 920.

The documentation is a bit spare on how custom rules should be handled in Validator. E.g., I am assuming that if you have multiple custom rules, they are all handled via decision trees in the "custom" configuration object. And if that is true, then I am assuming you have to do the same for the "message" configuration object if you want to have a different message for each custom rule.

However, it is not clear in the documentation how one should send the specific message text.

E.g., let's say we want to have two custom rules. 

• One rule checks the "firstname" input field and fails if the value does not include "Tom".  On failure, we want the message for that field to be "Please be a Tom".
• The other rule checks the "lastname" input field and fails if the value does not include "Smith". On failure, we want the message for that field to be "Please be a Smith".

Based on what examples I can find in the forums, my first guess at how one would do this looks like the following:


The above code is for illustration and has not been actually tested.

However, I do know that the line  return 'Please be Tom'; fails to place any text in the error message.

My hunch is that there is a specific formatting function that must be used. Any hints or leads, here, for what that might be?

TIA

Hi Everyone,
I'm quite new to Kendo UI Mobile on Icenium, and i'm currently trying to refresh the data i have on my mvvm viewmodel, basically i have a view model with a datasource and a function named showView: wich i would like to be called after the view is presented to the user, i tried seeking on the documentation but i wasen't unable to make raise data-show on my viewmodel. Could any one be so kind to provide me a working example, the viewmodel is created like the one on visual studio sample, with an added showView: function().. 
I need this because i need to load  fresh data from localStorage, do some stuff with it and populate the datasource to show a result on the screen.
 
Thanks
Sebastian

im calling the the api the response headers are empty.when i access the api it is working fine.Can anyone help how to intergerate the web api with the Kendo UI html pages.

Hi, 
I convert my MVC project to use Kendo UI. I have action result return simple Json object status with message if there is an error. It was working fine before I convert.
now it tries IE tries to download the Json, Firefox and Chrome will show it as text.

here is my code. I add  ("text/html", System.Text.Encoding.UTF8, JsonRequestBehavior.AllowGet) I was hoping it will fix it but it didn't

return Json(new { Success = true }, "text/html", System.Text.Encoding.UTF8,
                        JsonRequestBehavior.AllowGet);


 return Json(new { Success = false, Message = formPost.Message }, "text/html", System.Text.Encoding.UTF8,
                        JsonRequestBehavior.AllowGet);




form 

Ajax.BeginForm(new AjaxOptions { OnSuccess = "handleModalSubmit" })

JS


 function handleModalSubmit(result) {

        if (result.Success) {
            alert("Your request was sent Successfully");
            
        }
        else {
            alert("There was problem sending your request");

        }
    }



Here is my Kendo include files
