由 余生长醉 提交于 2019-11-27 07:28:07
I'm in the process of adding some UI functionality to a hybrid WebForms/MVC site. In this case, I'm adding some AJAX UI features to a WebForms page (via jQuery), and the data is coming from an MVC JsonResult. Everything is working 100%, with one exception: I would like to implement the XSRF protection of AntiForgeryToken. I have used it in combination with the ValidateAntiForgeryToken attribute on my pure MVC applications, but would like to know how to implement the Html.AntiForgeryToken() method in WebForms. Here's an example using a UrlHelper . I'm having some trouble getting ViewContext /

I'm building an ASP.NET MVC application, using VB.NET and I'm trying to apply a css class to a Html.ActionLink using the code: <%=Html.ActionLink("Home", "Index", "Home", new {@class = "tab" })%> But when I run the code I receive the below error: Compiler Error Message: BC30988: Type or 'With' expected. I'm new to MVC and really haven't much of a clue what I'm doing so I can't see what's wrong there as I'm using code based of an example elsewhere. It is: <%=Html.ActionLink("Home", "Index", MyRouteValObj, new with {.class = "tab" })%> If VB.net you set an anonymous type using new with {.class =

问题 New to MVC and have been running through the tutorials on the asp.net website. They include an example of a custom html helper to truncate long text displayed in a table.
