Jan 24, 2017 04:12 PM|satish_nagdev|LINK Hi,

can you try following ? I hope you”re getting ID correctly in first commented //alert before #delete-dialogue

//url: “/BookCategory/Delete/” + Id,url: “BookCategory/Delete”,data: JSON.stringify{“Id”:Id},

Jan 24, 2017 04:44 PM|PatriceSc|LINK Hi,

db is created in your controller constructor or could it be null? http 500 means that you have a server side exception which be default should have been written to the Windows event log. Then from the actual error message it should be easier to figure out what happens…

Jan 24, 2017 04:46 PM|mgebhard|LINK The confirm dialog is pointless since the AJAX success handler runs after the Delete command.

Try removing theValidateAntiForgeryToken attribute and retry. If removing theValidateAntiForgeryToken attribute works then you”ll need to implement a proper interface.

Otherwise, continue to troubleshoot. Try breaking down the code into testable chunks until you find the bug.

Jan 24, 2017 04:59 PM|satish_nagdev|LINK your data: parameter is not what I mentioned, not sure if you tried , 500 is indeed server side error, try debugging as suggested

data: “{Id:Id }”data: JSON.stringify{“Id”:Id},

Oct 30, 2017 04:15 PM|andersw|LINK The error:”Failed to load resource: the server responded with a status of 500 (Internal Server Error)” happened to me after I added two mimeMap lines to my Web.config

I think in one way or another they conflicted with the runAllManagedModulesForAllRequestswith the result that my web page ended up in some kind of error before loading the .css and .js files (when using localhost). So it seems to be either the one or the others.(The problem with loading .js and .css was not present, when my .js and .css links in the head sectionof my program was written with an absolute paths i.e. starting with http:// But using this method would make it diffecult to test my program why developing it).
