razor

问题 I'm trying to get a partial view to render using Razor in MVC5. When I use @{ Html.RenderPartial("ViewName", model); } I get the parser error: Unexpected "{" after "@" character. Once inside the body of a code block (@if {}, @{}, etc.) you do not need to use "@{" to switch to code. When I remove the {} , i.e.: @Html.RenderPartial("ViewName", model); I get the compilation error Cannot implicitly convert type 'void' to 'object'. What am I doing wrong? 回答1: You haven't posted the context of that

问题 When we have more than one possible form to post to the controller on the same cshtml page, the Antiforgery validation does not work. We went through the MVC3 code and we found the problem is in this part of the code: if (!String.Equals(cookieToken.Value, formToken.Value, StringComparison.Ordinal)) { // error: form token does not match cookie token throw CreateValidationException(); } The cshtml that we have is something like this: @using (@Ajax.BeginForm()) { @Html.AntiForgeryToken() <input

问题 First off, I know there is a duplicate, but I have tried the solution and it does not work for me. So, I need a faux-segmented control to be tabbable, or at least keyboard selectable. Getting the tab key to highlight the button is easy - I just add tabindex="0" To the element I want to be tabbable. Problem is, while I can get it to give the barely perceptible blue outline, I cannot select the button that's highlighted. The solution proposed in the other question was to make my radio buttons

问题 Is it possible in ASP.Net Core to automatically convert camel case property names in view models to insert spaces into the corresponding labels when using tag helpers?

问题 I have a razor view that will contain 5 forms. (A, B, C, D, E). Each of these forms has their own ViewModel (AViewModel, BViewModel, CViewModel, DViewModel, EViewModel). I created a parent ProductViewModel that the page will use as its only ViewModel. Within this ViewModel will be all of the other ViewModels for each form on the page (listed above). Here is what the ProductViewModel's properties look like: public AViewModel { get; set; } public BViewModel { get; set; } public CViewModel { get

问题 I am getting this error when I try to launch my website using WebMatrix. I have a .cs file which makes a call var db = Database.Open("dbase"); . I have a database in my project called "dbase". I have no web.config file and no imports for using WebMatrix packages since I am launching the site using WebMatrix, so I don't believe I should need them. Do I need to wrap the code in Razor tags, like @{var db = Database.Open("dbase"); } ? This causes an error for me too. What could be causing this?
