Detecting when an uploaded exceeds maximum attachment size?

The limit in size for an attachment is 5MB, however when using an apex:inputFile controller the result of attempting to upload a file larger then that is a null object. Is there a way to detect when the file atempting to upload is larger then the limit?


To avoid maximum view state error you can use transient keyword as a prefix with your properties to which you have assigned in <apex:inputfile>


I'm not having issues with the view state. The problem I'm trying to detect is when a file larger then the maximum excepted attachment size is selected. The file just gets nulled in apex when that happens and I cant tell the difference between a file thats too large and no file at all.

Hi Vintara,

Are you able to find any solution for this?
