ASP.NET MVC does browser refresh make TempData useless?

Question

If I redirect to a new page passing TempData to initialise the page it works fine, however if the user presses the refresh button in their browser the TempData is no-longer

Answer 1

Tempdata is used across redirects so if you are refreshing the page that means you are making a separate request to the server so that is why your data gets lost. To persist this data call Tempdata.Keep("KeyofTempdata") method in the action to which you are redirecting. If you want to remove data use Tempdata.Remove("KeyofTempdata").
