Alert Dialog handler in popup window is giving error on click of button in WebAii

Hello Boyan Boev,

      Sorry for delay.Actually I send all the Source to You I am not having anything else.My Problem is Popup alert handing in Chrome.

Consider that you enter all the detail in any one of the Registration form without Saving you are clicking cancel at time you will get a Popup Alert "Details are not yet saved.Do you want to proceed?" with OK/Cancel button.At that time I want to find the alert and click Ok (or) Cancel button using C# code.

    I am doing testing in visual studio 2010 using telerik Plugin.
