    I have received a code to set up application. That application have implemenmted BingMapAPI. All other pages are working fine except BingMap page. As per code , developer has created User control of Bing Map in Sitefinity . This code is working on main server but I am getting following error on Localhost. -

    This property cannot be set to a null value.

    Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

    Exception Details: System.Data.ConstraintException: This property cannot be set to a null value.

    Can anybody help to get out of this?

    Is it issue of bingmapsapikey?

    Do I need to ask for Devloper key ?

    Hello Bhushan,

     Is this error thrown only on the page with the Bing control? If you are getting it only on your development server, then I suppose it is a problem with the bing API itself. Maybe it doesn't connect properly and wherever it is supposed to return a value, it returns null and this is why such an error pops up.
