I have a route (the first one listed) which looks like this:
routes.MapRoute( "TopicRoute", // Route name "forums/{forumSlug}/{topicSlug}", // URL with parameters new { controller = "Forums", action = "Topic"} // Parameter defaults );
I can browse to: /forums/my-forum/my-topic and the page loads fine. Yet I have a Html.ActionLink that looks like: @Html.ActionLink(item.Title, "Topic", new { forumSlug ="my-forum", topicSlug = "my-topic" }) And it won't generate the correct link syntax for me? It generates: <a href="">My Topic</a>
I'm having problems getting my CSS class to style an actionlink inside a html.partial. In building my test site, I've used the template beginning from ASP.NET and the standard login portion. My Index page works fine as the _Layout.cshtml does reference my css page. In _LogOnPartial, I have the following listed (there is more but this is what's important I believe):
That looks right but it's not showing it correctly. The font isn't Helvetica and it is underlined and not white. I don't reference the css sheet in the LogOnPartial but I didn't think I'd have too.
It's a little unclear for me on when to use a custom helper method and when to use RenderAction and also when to simply use ViewData instead. Some of their functions overlap slightly.
For example, if I were to create a Category navigation bar, would I create a new helper method and place that in some partial view? I had initially though of doing this, but I read on some blog to use RenderAction instead.
Assume the list of categories is coming from some data source.
If i do the following the content is html encoded. <%= Html.ActionLink("<img src='/images/icons/tick.png' />More info", "OrderRegion", "Campaign", new {id = Model.Campaign.Id}, null) %>
im extending the htmlhelper. but it i cannot call the renderaction of it.
using System.Text; using System.Web.Mvc; using System.Web.Mvc.Html; public static class ViewHelpers { public static string Text(this HtmlHelper htmlHelper, string name, object value, bool isEditMode) { htmlHelper.RenderAction(...) //cannot be called } }
I am working in an environment with many teams who are responsible for specific content on pages. Each team is sharing specific information (common class libraries, and master pages) that each are going deliver different types of content.Is it possible for an MVC application to do something similar to RenderPartial and pass a model to another MVC application Controller/Action to return content?
So the code for this might look like: (http://www.mydomain.com/Home/Index)
After rendering a view on a Post, a call to RenderAction inside the view will call for the Post method. Is there any way to specify I want to call the Get method instead of the Post?
In my Site.Master View, I have the following line:
[Code]....
If I don't include the string identifying the Controller to use, I get an error stating that the PrimaryNavigation method couldn't be found in the Home Controller. Since the Site.Master View is in the Shared Views folder, I would have thought that the Shared Controller would have been used.
I get an HttpException (details below) after installing Visual Studio 2010 Pro RTM in an application developed using Visual Studio 2010 RC. The platform used was ASP.NET MVC2 RTW (already under VS10 RC).
I first uninstalled all RC software and even ASP.NET MVC 2, and then did a "clean" install of VS10 RTM. The ASP.NET MVC 2 version now installed on my dev machine is 2.0.50217.0.
Exception Message: Error executing child request for handler 'System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerAsyncWrapper'.
InnerException Message: <FilePath>ViewsLanguageRenderLanguageNavigation.ascx(6): error BC30451: 'Model' is not declared. It may be inaccessible due to its protection level.
The error occurs on this "Html.RenderAction":
[Code]....
The "LanguageController" just calls into another service function as below:
[Code]....
Does anybody have an idea what is causing the problem?
Edit:
By the way, I might also share the actual view (partial view) that would show the languages to select from:
I think I need to drop in some escape characters, but I'm not quite sure where. Here is the javascript function I'm attempting to call:
function setData(associateValue, reviewDateValue) { var associate = document.getElementById("Associate"); var reviewDate = document.getElementById("ReviewDate"); associate.value = associateValue; reviewDate.value = reviewDateValue; }
Here is the asp .net mvc line where I'm attempting to create a Radio button with a click event that calls the above function and passes data from the model as javascript parameter values.
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('<%=item.Associate%>','<%=item.ReviewDate%>' )" } )%>
The above throws a bunch of compile issues and doesn't work. A call such as the following does call the javascript, but doesn't get the data from the model.
I'm pretty new to ASP.Net / MVC 2. Can anyone explain how to use the Html.ActionLink thing? I understand that the first parameter is the displayed text, but for the second one, what is the action name?
I have an ActionLink: <%: Html.ActionLink("MyAction", "MyAction") %> I would like to use a button instead. Something like this: <asp:Button ID="Button1" runat="server" Text="MyAction" /> What do I need to do to make clicking the button perform the same action as clicking the ActionLink?
I have a simple ASP.NET page that uses the VLC media player to play a video in IE. I also have four buttons to control the playback:
Play, Pause, Stop, and Mute
The four buttons call JavaScript functions that access the ActiveX control. When I click on any of the buttons, I get the following error in the JavaScript function:
"Microsoft JScript runtime error: 'vlc' is undefined".
However, if move the object tag for the vlc player outside the form tag, then the JavaScript works correctly, and I can control the video playback.
My question is why must the object tag be outside the form tag for this code to work correctly?
I was reading the ASP.NET MVC Best Practices article by Rashid, and got stuck in his description of creating UrlHelper extensions. Doing this is easy enough, and I've adopted the practice into all of my projects. I noticed, however, that Rashid used Url.Content to generate the url for the home page, and Url.RouteUrl for all the other urls. Why is this? What is the difference between the two?
The link to the blog post is here: http://weblogs.asp.net/rashid/archive/2009/04/01/asp-net-mvc-best-practices-part-1.aspx
I've used Html.ActionLink in my Views, but I'm wondering what difference it would be if I used Url.RouteUrl instead. Does anyone have a good grasp of what makes these helpers different, and where they are best used?
