I am getting duplicate entries sometimes when I insert data in Sql server

The logic provided her prevents duplicate entries on page refresh using the browser refresh button

But If the user is inputting same data again and again and saving then this logic cannot do anything.

You will have to  check whether entries exists before inserting

Hi Mudassar,

I have checked the code, after inserting in the database it is redirected to home page and even if you click on back button, you will automatically get a issue number which is incremented by one.

I dont think browser refresh has to do anything with this.

That's what I told you. You need to make checking in your SQL Stored Procedure that if record exists donot insert.

The article you are referng is strictly for Page Refresh. It does not do anything other than that
