I have been using the trial version of DevComplete. I've been building a web app using Kendo UI MVC. Up until this point I haven't had any issues. However, a couple days ago I purchased DevComplete. I installed the production Kendo.MVC dll in my project. Now my app is not working. When I attempt to load any page with a Kendo UI Grid, I am getting a JavaScript error that says kendo.synchReady is not a function. 

The actual code that Kendo is generating, in part, looks like this:

kendo.syncReady(function(){jQuery("#grid").kendoGrid({"columns":[{"title":"Last Name","headerAttributes":{"data-field":"LastName","data-title":"Last Name"},"width":"150px","field":"LastName","encoded":true,"editor":"...

Can someone tell me what happened? The only change I've made was to install the production Kendo.Mvc.dll in place of the trial version.

I got the same error. I use kendo version 2017.1.223.545 and jquery version 3.1.1.

Please see error on captured screen attachment.

Thank you

I'm sorry. I forgot to tell that I still can't find the solution yet, so please help.

Thank you.

I'm getting this error too. It seems to be when I'm using the Kendo.Mvc.dll 2017.1.223.545

HI 

  I gettting this error too.I'm using the Kendo.Mvc.dll 2017.1.223.545 .Styles and js also for 2017.1.223

I'm getting this error too. I'm using the Kendo.Mvc.dll 2017.1.223.545 

styles and js also for 2017.1.223

We are having this issue as well. After upgrade we tried it with both CDN and local script files.

A new project from the MVC template runs fine though.

Any update on this? I experiencing the same issue after updated to 2017.1.223

If you guys are using the custom download option, I was able to get rid of the error by selecting all options under the core framework list.  Although I dont need all in this list, my instinct tells me something is off with the core files.

Framework

Shared components providing behaviors, data access and other services

Hi Konstantin,

I downloaded the 2017.1.223 version and then manually copied into my project the CSS and JS files.  I'm still getting that kendo.syncReady is not a function issue.  I'm assuming that if I copied over the kendo.aspnetmvc.min.js from the "UI for ASP.NET MVC R1 2017" folder that it is the right one.  Am I wrong?

Hello,

I am using Kendo.Mvc version - 2017.1.233.545.  My project was running fine with an older version of Kendo but now, i get an error, 

kendo.syncReady is not a function. 

This thread mentions several ways to fix.  Kendo team, please provide your response on how this can be resolved. 

I just created a brand new project to test. Still having the issue using all 2017.1.223 versions of the files. Website still comes up and states that kendo.syncReady is not a function.

Now when I forcefully include script src="@Url.Content("~/Scripts/kendo/2017.1.223/kendo.aspnetmvc.min.js")" into my scripts it works as expected.

We discovered this when a new starter downloaded the latest UI for ASP.NET MVC which was R1 2017.

Our existing application was using the files from R3 2016 and we began getting the error saying "kendo.syncReady is not a function".

To fix this this we just installed the previous version (R3 2016 from the Telerik website) alongside R1 2017 and swapped over the Kendo.Mvc dll.

I also came across this error and temporarily overcame it by explicitly including 

<script src="@Url.Content("~/Scripts/kendo/2017.1.223/kendo.aspnetmvc.min.js")"></script>

into my _Layout.cshtml.

However this is temporary and I expect an official solution from Telerik.

I came across this error. I found the issue. I am using local resources, I have copied all the required scripts and css files to the corresponding location. 

I was hoping that by doing this will fix the problem after rebuilding the solution/project. I have overlooked the browser cache issue everyone experiences with js files. After struggling for a while, I did hard refresh on the browser ctrl+F5 which loaded latest js files and its fixed.

Hope this helps

Hi Stefan,

I used to get the latest builds, copy js and dll into my project, test and run. With 2017.1 and the "syncReady" error I no longer to this.

I'd really like an official article explaining the trouble and an official solution, so I could upgrade to 2017.

Hi Stefan,

thanks for you reply. However, I'm not sure I understand.

Previously in this thread you mention, that "...this is a new function introduced in 2017..." and several posters incl. Kendo staff refer to including kendo.aspnetmvc.min.js to fix the problem.

In your last post, you say that the error is caused by an incorrect version upgrade, and not by a newly introduced function. 

I would be really happy if you could clarify.

Thanks in advance.

We are experiencing the same issue with kendo.syncReady.

We are using the following:

* Kendo.Mvc.dll version 2017.1.223.545.

* Kendo UI for JQuery Javascript files version 2017.1.223

* JQuery Version 2.2.4

* RequireJS Version 2.3.3

Our code that is failing. Note that "Start" is a global function that is a RequireJS wrapper for document.ready:

    start(function () {
        require(['kendo/kendo.window.min'], function () {
            kendo.syncReady(function(){jQuery("#enrollmentWizardWindow").kendoWindow({"modal":true,"iframe":false,"draggable":true,"scrollable":true,"pinned":false,"title":null,"resizable":false,"actions":["Close"]});});;
        });
    });

Attached are screenshots proving this. As you can see in the "network tab of Chrome" screenshot, the kendo.aspnetmvc.js file is loading before the JavaScript on the HTML page executes.

Please give us an ETA of when this critical bug is fixed so we can adjust our current release timeline.
