    If I add a Report Viewer to my web page, non master. upon debugging I get this error

    Unhandled exception at line 15, column 16485 in http://localhost/SpecCenter/Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=RadScriptManager1_TSM&compress=1&_TSM_CombinedScripts_=;;System.Web.Extensions,+Version=,+Culture=neutral,+PublicKeyToken=31bf3856ad364e35:en-US:6b5ccaa5-a290-46bd-afb1-b6039033842c:ea597d4b:b25378d2;Telerik.Web.UI:en-US:4b258e7c-7002-4d3e-9fa4-709d417eed98:16e4e7cd:f7645509:22a6274a:ed16cbdc:24ee1bba:c128760b:1e771326:88144a7a:8c2d243e:f46195d3:4cacbc31:dc752f02:58366029:4b09f651:ac926cdd:2003d0b8:2bef5fcc:a9b7ace7:6b3f73b3:e330518b:8e6f0d33:864068a5:6a6d718d:52af31a4:74603f77:6d43f6d9:78b9daca:8674cba1:7c926187:b7778d6c:c08e9f8a:59462f1:a51ee93e:19620875:874f8ea2:c172ae1e:9cdfc6e7:c8618e41:e4f8f289:1a73651d:16d8629e;System.Web.Extensions,+Version=,+Culture=neutral,+PublicKeyToken=31bf3856ad364e35:en-US:6b5ccaa5-a290-46bd-afb1-b6039033842c:76254418

    0x800a139e - JavaScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Value cannot be null.

    Parameter name: key


    if I remove the report viewer the page loads and functions as expected.

    Hello Troy,

    Based on the error message, please check if BrowserLink is enabled in Visual Studio, and test running the application with disabled BrowserLink as it may intersect AJAX requests.

    Let us know how it goes.
