问题 I cannot seem to add an image in html. I'm using ASP.net MVC 3. My image, named KeyLargoPic, is located on a flash drive in the folder X:\Project\Project\Photos\Key Largo, and it appears to be a JPEG. The code is as follows: <td><img src="X:\Project\Project\Photos\Key Largo\KeyLargoPic.jpg" alt="IMAGE" /></td> Every time the page loads, it shows the box with "IMAGE" inside. Does anyone know what I'm doing wrong? 回答1: Add the image to your project, probably in the content directory, by right

问题 I am having an issue using the RadioButtonFor helper. When the value passed in is true, it isn't displaying a "check" in either radio button. When the value is false, it works just fine. I copied this code from the project I am working on and created a sample application and I was able to replicate the issue. If I hard coded the value to true or false it seems to work, but when I use the "!string.IsNullOrEmpty(allgroups)" it doesn't. From the View: <div> @Html.RadioButtonFor(m => m.AllGroups,

问题 I have an interesting problem with the TempData object not passing values to another controller. I set TempData["Enroll"] in the Enroll Controller 's HttpPost method to an Enroll Model.

问题 I am trying to generate the full URL for a route link in my razor view for ASP.NET MVC 3. I know I can use Html.RouteLink to generate a link however all I want is the URL, not the surrounding a tag wrapper. Is there a way to do this? 回答1: Use the UrlHelper. Url.RouteUrl( "MyRoute" ) 回答2: Are you talking about: <a href="@Url.Action("Action", "Controller", new { @id = "2" })"> Link to Page</a> vs. @Html.ActionLink("Link to page", "Action", "Controller", new { @id = "2" }) The Url Model builds
