I Have local Database in which all records are maintained for fast user access and not to put load on the server but i want to make a sync button when this button is clicked then all of the local data is pushed to Azure SQL database for record keeping. i have everything set up but just this thing is cause a lot of trouble.

Any help will be greatly apprec

I have not tried it myself yet, but I think you can take a look at Transaction Replication towards Azure SQL Database.
