Strange Error with SQL Report Viewer 2012

[James Daresta]

I have a page with SQL 2012 Report Viewer on it and using my global clientside error handling I get occassionally a popup telling me an error is occuring within the Telerik.Web.UI.WebResource.axd (attached). It is an Object Expected error. I have tried several things to eliminate, but have failed. Below is my html code for the page. I am only including parts of the master page. Note I had to use the UpdatePanel as the report viewer had issues with the Ajax Manager and it doing ajax calls.

Master Page

function Master_GlobalErrorHandler(message, errorURL, lineNumber) {

    var outputMessage = "An error occurred with the following details:\n\nMessage: " + message + "\nURL: " + errorURL + "\nLine Number: " + lineNumber + "\nUser Id: <%=lblLoggedInUser.Text %>\n\n\Please send this information to the help desk and the actions you were doing. Thank you.";

     

    $.ajax({

        type: "POST",

        url: "<%=(OlinCA.SalesCRM.Web.URLUtilities.GetAbsoluteURLBase() + OlinCA.SalesCRM.Web.URLUtilities.GetApplicationPath())%>Services/ErrorSendMail.asmx/SendMail",

        data: "{ 'FromAddress' : '[e-mail]', 'ToEmailAddresses' : ['[e-mail]'] ,'Subject':'Sales CRM Client Side Error <%=System.Configuration.ConfigurationManager.AppSettings["CurrentRegion"].ToUpper() %>','Body':'" + outputMessage + "','ReplyTo':'[e-mail]','IsBodyHtml':false}",

        contentType: "application/json; charset=utf-8",

        dataType: "json"}); 

    alert(outputMessage);

}

 

window.onerror = Master_GlobalErrorHandler;

$(document).ready(Master_InitializePage);

Hi James,

Try to temporary replace you RadScriptManager with regular ScriptManager control. Also disablle Telerik Ajax by setting EnableAjax property of RadAjaxManager to false.

Let us know whether this helps you avoid the error.
