How to Tackle View State Issue During Upload file as a Attachment through Visualforce Page

In Previous Post, We Saw How to Upload File in Salesforce Through Visualforce .

So This Post is just to Handle the View State Error Occurred During Uploading File through Visualforce.


For Complete Detail of View State Refer Link .

If you look into the Previous Post there were many Variables in Apex Controller which were use for getting file Body, Name, Description .



So If User Upload Large File Then file Body, Name and Description Come in these variables and It would Easily Increase the Heap Size Limit and View State Issue would arise.

4thSo For Avoiding this Issue Directly Make a Attachment Object Instance in Apex Controller and Get Body, Name of File From Visualforce Using that Instance .



Instead of Storing file body, Name, Description in these variables in apex controller it would Store directly in SObject Attachment So Heap Size Limit will not exceed.

Please Refer the Visualforce Page and Apex Controller for More Details.
