    We were using ASP.net AJAX Q2 2013 along with VS 2010 for our development. Recently we upgraded the environment to VS 2013 and Telerik  ASP.net AJAX Q3 2013 RAD Controls.  Now we find that in all the web pages where we have the RAD Date picker, the control flickers in IE11 on post back. Also for drop down lists, the user has to click twice to get it working. There is a considerable slowness in these controls.  This is happening only in IE11 and works fine in chrome.  This was working correctly in IE 11 when we were using Q2 2013.  We cannot tell our clients to use chrome since our application works best in IE. 

    We are now hesitating to provide our latest build to our clients due to the slowness of these controls.  What could be the possible issue and are there any workarounds or fixes for this? An early action from your end is appreciated.  

    Thanks and Regards

    Hi Rajendran,

    Based on the provided description it is rather difficult to determine what exactly is causing the issue. Could you please provide some more information on your scenario and test the approaches below for optimizing your project:
    • Try using RadAjax for ajaxifying the controls and prevent flickering.
    • You could set Shared Calendar for the RadDatePickers control in case more than one is used on the page.
    • Please inspect the server resonance in the browser's console and verify if any js errors appear when the drop down list failed to open.
