Given a string in my database like "Computer Gadget", I am trying to achieve a url format like "http://xyz.com/products/details/computer-gadget" when a user clicks a link to the item "computer gadget" from a list view.In my list view for the products, I have Action links that read like this
When I hover over this link on the rendered page I get a link that looks like "http://xyz.com/products/details/computer+gadget"and the correct product detail is returned after I have url.decoded the string in my Details method. However, the returned page displays a url that looks like "http://xyz.com/products/details/computer%2bgadget"How can I get the returned url to show "computer-gadget" instead?Also when a name has "&" or "/" the server throws a Http 400 error message. I know these are unsafe values, but is there a way to work around this safely to allow the strings keep these characters?
