Can you paste your code?

As a suggestion, check if any row is selected or not before save in DB , also clear selection after save.

You have to implement PRG pattern to avoid above issue.Please read below link for more info.

PRG:
What is the PRG Pattern ?
PRG stands for "Post/Redirect/Get"
Instead of returning an HTML page directly,
The POST operation returns a redirection command (using the HTTP 303 response code (sometimes 302) together with the HTTP "Location" response header),
Instructing the browser to load a different page using an HTTP GET request
The result page can then safely be bookmarked or reloaded without unexpected side effects

Post-Redirect-Get with ASP.NET

You can put condition inside your query like
Ex.

if not exists(select col1 from table1 where col1=@col1)
begin 
  insert into table1(col1)values(@col1)
end
