My view has a link to an actionresult where a user chooses a part, and goes to GetPart. The problem I have is getpart is leaving its Part=######### after it gets redirected back to my InsertNewRecord Action. This is bad because when I go to post my action, it errors out! Is there a way to clear that query string out at all? Or redirect to the action without passing it?
http://localhost:56195/List/GetPart?Part=159951159[^]

Edit: Basically, I just want to get back to localhost:56195/Create/InsertNewRecord after setting my static variable. What I am getting instead is a redirection to my desired action, but the url is still looking at localhost:56195/List/GetPart?Part=1599551159.
