Hi Rahul,

I see that my colleague Ianko has already replied in the other thread regarding the same topic. For convenience below, you will find his answer pasted:

The same will happen with every component that utilizes the newly added styling options (themeColor, size, etc.). 

Currently, I can suggest you add the following patch to support IE10: 

    var originalInit = kendo.ui.Widget.fn.init;

    kendo.ui.Widget.fn.init = function(element, options) {
      if(!this.__proto__) {
        this.__proto__ = Object.getPrototypeOf(this);
      }, element, options);

Here you are a dojo example to check it out: Note that the Captcha service is currently not working with the dojo, but this is only to show how to utilize the patch. 

I would recommend keeping the conversation in a single thread.
