So I have an ASP.NET 4.6 website using C# via visual studios 2015. Say I have a page with a textbox control and I open the same page on a browser twice, either on different tabs or windows.

When I type into one input box, say on browser tab 1 or window 1, the same input on the other tab/window immediately contains the same text. How can I stop this from happening without programmatically changing the ID on page load to something random?

I've tried changing the session but that did nothing for me. This is also happening on a brand new website I made just to test with and all browsers I've tried.

See example here

I'm an idiot, the solution was browser link in visual studio had "Enable Browser Sync" turned on which was the issue.
