    Hello Telerik Team,

    We have used the UI for ASP.NET AJAX Telerik toolkit in our application. Recently we have upgraded the Telerik version from older version “2012.2.724.35” to the new version “2014.2.724.45”. After upgrading the Telerik version we are facing some functionality issues. We need your help on identifying the fix for following mentioned issue. 

    Following is the issue which we are facing after upgrading Telerik Version to “2014.2.724.45” i.e. UI for ASP.NET AJAX Q2 2014:

    Issue: Basically the issue is, we have used a Telerik combobox and on its OnClientDropDownOpening="OnClientDropDownOpenedHandler" event, we have written a JavaScript function which will scroll the vertical scroll bar of that combobox at the top every time we will open that combobox for the first time. Now before upgrading the Telerik version to “2014.2.724.45” our JavaScript function used to work properly and it returned the object with proper data. Please refer the attach image "BeforeTelerikUpgrade.png"

    Now, after upgrading the Telerik version to “2014.2.724.45” the same JavaScript function that we have written on the OnClientDropDownOpening="OnClientDropDownOpenedHandler" does not return the proper result. Please refer the attach image "AfterTelerikUpgrade.png".

    Just to let you know we haven’t done any code changes to the JavaScript function after upgrading the telerik version. We are using IE7 document mode for our website. Also after upgrading the Telerik version to “2014.2.724.45” whenever we scroll the vertical scroll bar of that combobox then it forcefully goes at the top and starts flickering which did not used to happen before we have upgraded the Telerik version.

    Please can anyone help us to identify the fix for this problem? Is this the issue related to the upgraded Telerik version“2014.2.724.45”? And is there any other workaround to resolve this issue without breaking our existing functionality where when we click on the combobox then the vertical scroll bar will remain at the top position?
