The Telerik DatePicker is malfunctioning in Internet Explorer 10

While developing my ASP.NET website, I have incorporated Telerik controls for date and time pickers. Everything is functioning smoothly across various browsers except for IE 10. Upon running the script debugger, an error message was displayed:

SCRIPT5007: Unable to get property 'documentElement' of undefined or null reference Telerik.Web.UI.WebResource.axd, line 166 character 2

Is there anyone who can provide guidance on how to resolve this issue?

Thank you in advance!

Answer №1

I made an update to my web.config file under the system.webServer section by adding these lines:

<httpProtocol>
  <customHeaders>
    <clear />
    <add name="X-UA-Compatible" value="IE=9" />
  </customHeaders>
</httpProtocol>   

After implementing this change, the issue was resolved successfully.

Answer №2

Check out the solution at this link

Make sure to include the following code within the <head> section,

<meta http-equiv="x-ua-compatible" content="IE=9">

Answer №3

Sharing my response from the Telerik community:

For those facing issues with compatibility mode or upgrades, we have created a JavaScript patch that relies on jQuery.

$(function(){
    if (typeof(window.$telerik.getLocation) == 'function' && Sys.Browser.agent == Sys.Browser.InternetExplorer && Sys.Browser.version == 10) {
        window.$telerik.getLocation = function(a)
        {
            if (a === document.documentElement) {
                return new Sys.UI.Point(0, 0);
            }
            var offset = $(a).offset();        
            return new Sys.UI.Point(offset.left, offset.top);
        }
    }
});

A potential issue to note is that when a date or time picker element fades out, the iframe may display the unstyled word "false." Please be cautious if considering using this patch.

Further investigation revealed that this version of RadDatePicker functions properly in IE11 but not IE10.

Answer №4

The reason for this error message is because it appears that you are utilizing an outdated version of Telerik. It is recommended to upgrade to the most recent Telerik version if your target audience includes users on modern browsers like IE 10.

Additional Information
Error in IE 10 due to telerik dlls Version=2009.2.826.35

Following ihorko's advice worked perfectly for me. For those using Windows 2008 server (IIS 7), simply follow ihorko's suggestions. If you are working on a Windows 2003 server (IIS 6), use the following command:

cscript adsutil.vbs set w3svc/HttpCustomHeaders "X-Powered-By: ASP.NET" "X-UA-Compatible: IE=9"

You can save this line in a bat file and execute it from the c:\inetpub\adminscripts folder

Upgrading the Telerik suite is not just about paying the bill and replacing a dll. New versions may behave differently and require thorough testing. Changes in layout might occur when utilizing the telerik form decorator - an earlier 'bug' regarding margins has been fixed, but implementing the fix might lead to layout distortion after an upgrade.
