    I am using an old licensed version of the Telerik TabStrip. I am using IE 10 and 11. I am now getting javascript errors when I use the TabStrip on a web page. The error is window.attachEvent("onunlo\x61d",this.O9); Object does not support attachEvent. How would I fix this?


    The dll shows as
    RadTabStrip.Net2.dll

    Assembly Version 3.4.1.0

    Hi,

    The issue stems from the fact that the attachEvent method is no longer supported by the latest IE as announced in msdn.microsoft.com.

    Please note that the mentioned version of the Telerik controls is no longer supported. Therefore it is expected that you might be experiencing issues related to new browser versions. The issue you have faced should not be present in the Telerik UI for ASP.NET AJAX latest version. For this reason we would suggest that you use the latest version of the Telerik controls that are designed to be compatible with the latest browsers.

    For more information you can refer to Telerik Support Lifecycle Policy.

    I figure that would be the answer. I downloaded the demo version of Telerik UI for ASP.Net AJAX Q2 SP1. I need to know how to change my existing web site to use the new version. I do not have the time to completely rewrite the application. Where is good documentation to do this and to add the controls to the VS 2010 Toolbox.

    Hi,

    Adding controls to VS 2010 should happen automatically after installing Telerik UI for ASP.NET AJAX. More information about it may be found in the Adding the Telerik Controls to the Visual Studio Toolbox help article.

    You may also need the Upgrading a Trial to a Developer License or to a Newer Version help article that contains resources on updating process.

    And you would most probably need reference about the current state of the controls. You may find that in the Controls section of the documentation referred in the above two links. For quick controls link reference, you may use the Introduction page of Telerik UI for ASP.NET AJAX documentation.
