iframe good or bad for my MVC web-app scenario

阅读更多关于 iframe good or bad for my MVC web-app scenario

I've been working into intranet web solutions which are to be used by a specific set of users of a system - like supply chain management. No SEO or marketing - only easy of use and simplicity that appeals them and makes their task simple. I'm using MVC2 with ASP.Net. I'll explain my scenario in generic terms. I've a page which has a tab view. The first tab loads a record from a master table and the other tabs load data for some details table. And ideal example would be like: Tab 1: Add/Edit Customer (master) record Tab 2: Add/Edit Orders for a Customer Tab 3: Add/Edit Items for an Order
