    Sometimes I got javascript error (I translated error message by myself from polish):

    err_msg = Could not get property „getTextElement” for not defined or null reference (line 16762)
     
    documentState = completed
     
    url = .../Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=ctl00_RadScriptManager1_TSM&compress=1&_TSM_CombinedScripts_=;;System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35:pl-PL:7dd8b7c5-dd18-48e6-97c2-5a5a060b2752:ea597d4b:b25378d2;Telerik.Web.UI:pl-PL:ead0d100-d31b-4d13-9451-88908208aae7:16e4e7cd:f7645509:22a6274a;||:4c5db2b2:de3312b1:eff1b1fc;Telerik.Web.UI, Version=2015.2.729.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4:pl-PL:ead0d100-d31b-4d13-9451-88908208aae7:24ee1bba:c128760b:874f8ea2:19620875:4877f69a:f46195d3:92fe8ea0:fa31b949:490a9d4e:bd8f85e4:cda80b3:383e4ce8:e330518b:2003d0b8:88144a7a:1e771326:c8618e41:1a73651d:333f8d94:ed16cbdc:e524c98b:b7778d6c:6d43f6d9:407acb1c:e4f8f289

     

    I could not reproduce it while developing, but on production this error appears quite often. I suppose that mentioned Javascript code tries to refer to control (button) when it is not rendered yet, but I have no idea how to resolve it.

    Hello Lukasz,

    Without a reliable way of reproducing the exception we would not be able to determine what causes it. Please isolate and attach a sample runnable project, which demonstrates the exception. You can find our guidelines for isolating a problem in this blog post.
