Hi,

I'm developping an ASP.NET MVC application using Kendo UI v2014.1.415. Some of the Kendo controls are not rendering properly in Release mode. I check the the css bundle I found the following :
/* Minification failed. Returning unminified contents.
(27,35175): run-time error CSS1030: Expected identifier, found '.'
(27,35182): run-time error CSS1031: Expected selector, found ')'
(27,35182): run-time error CSS1025: Expected comma or open brace, found ')'
*/

Here is the code from my bundle config :

bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
"~/Scripts/jquery-{version}.js"));

bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
"~/Scripts/jquery.validate*"));

// Use the development version of Modernizr to develop with and learn from. Then, when you're
// ready for production, use the build tool at http://modernizr.com to pick only the tests you need.
bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(
"~/Scripts/modernizr-*"));

bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
"~/Scripts/bootstrap.js",
"~/Scripts/respond.js"));

bundles.Add(new StyleBundle("~/Content/css").Include(
"~/Content/bootstrap.css",
"~/Content/site.css"));

//Kendo UI - Begin
const string VersionKendo = "2014.1.415";
const string KendoScriptFolder = "~/Scripts/kendo/" + VersionKendo + "/";
const string KendoCssFolder = "~/Content/kendo/" + VersionKendo + "/";

bundles.Add(new ScriptBundle("~/bundles/kendo").Include(
KendoScriptFolder + "kendo.all.min.js",
KendoScriptFolder + "cultures/kendo.culture.en-US.min.js",
KendoScriptFolder + "cultures/kendo.culture.fr-FR.min.js",
KendoScriptFolder + "kendo.aspnetmvc.min.js"
));

bundles.Add(new StyleBundle("~/Content/kendo/css").Include(
KendoCssFolder + "kendo.common.min.css",
KendoCssFolder + "kendo.metro.min.css",
KendoCssFolder + "kendo.default.mobile.min.css"));

// Clear all items from the default ignore list to allow minified CSS and JavaScript files to be included in debug mode
bundles.IgnoreList.Clear();

// Add back the default ignore list rules sans the ones which affect minified files and debug mode
bundles.IgnoreList.Ignore("*.intellisense.js");
bundles.IgnoreList.Ignore("*-vsdoc.js");
bundles.IgnoreList.Ignore("*.debug.js", OptimizationMode.WhenEnabled);
//Kendo UI - End

BundleTable.EnableOptimizations = true;

How can I fix this?

Hello again Alexandre,

This is indeed an odd issue - do you still get the same minification error with the latest SP version? Also can you please check with your browser's developer tools what prevents the grid pager UI elements from being served properly? This information can help us find the source of the issue.

If this does not help, the best means to proceed is to isolate a simplified working sample of your project and send it attached to a private support ticket. Thus we'll be able to investigate further and provide an appropriate explanation/fix.

Kind regards,
