问题 I have a partial view that has something like this <%= Html.DropDownListFor(m => m.SelectedProductName, Model.ProductList, "Select a Product") %> Now you can create a new product and edit an existing product. Both editing and creating use the same form. The create is on the main page on load up. Edit pops up in a jQuery UI model dialog and renders a new partial view. So as far as the page is concerned I have 2 dropdown boxes with the same "id" which is bad since they should be unique. So how

问题 I am loading .aspx and .ascx files as StreamReader . I want each file to register it's javascript and stylesheet dependencies in some declaration like a <%@ ClientDependency path="~/Scripts/jquery-1.4.1.min.js" %> .

Also, what are the guidelines for custom <%@ blocks in ASP.NET? Also, please retag this question if you can think of

问题 I'm used to the ASP.NET Webforms easy way of doing AJAX with UpdatePanels. I understand the process is much more artisanal with MVC. In a specific case, I'm using Data Annotations to validate some form inputs. I use the HTML.ValidationMessageFor helper to show an error message.
