Like Html.RenderAction() but without reinstantiating the controller object

I like to use the RenderAction extension method on the HtmlHelper object to render sidebars and the like in pages, as it allows me to keep the data access code for each such part in separate methods on the controller. Using an abstract controller base, I can define a default "sidebar strategy", which can then be refined by overriding the method in a concrete controller, when needed. The only "problem" I have with this approach, is that the RenderAction is built in a way where it always creates a news instance of the controller class, even when rendering actions from the controller already in

Asp.Net MVC 3 - @Html.Action won't render/return any HTML

I've been moving a fairly new project from ViewPages to Razor today, and all seems to be going well. Except I'm trying to use Html.Action to render a user control and it won't render anything. So I have a Shared/_Layout.cshtml file which is referenced in Home/Index.cshtml Index.cshtml has the following: <article> @Html.Action("LatestBlogsMainPanelWidget", "Blogs") ... </article> I've put traps in the BlogsController, so I know that's being requested. I also know that a model is being returned, that the LatestBlogsMainPanelWidget is being found by the view engine, and even some dummy Razor

问题 I have a few views on my website that i need to include on a start page. However, just using Html.Renderaction renders the master page and the whole shebang. How would i go about just rendering the content? 回答1: There are a few ways. Make sure your returning PartialView from your Controller. return PartialView("MyView"); Or you can set Layout to String.Empty or null inside the view. @{ Layout=String.Empty; } 来源： https://stackoverflow.com/questions/6134744/rendering-views-without-master-page

Html.Partial vs Html.RenderPartial & Html.Action vs Html.RenderAction. can any one please describe the difference

In ASP.NET MVC, what is the difference between: Html.Partial and Html.RenderPartial Html.Action and Html.RenderAction Html.Action invokes the controller's action, which means it instantiates the controller entity, calls an action method, which builds a model an returns a view result. Html.Partial uses already created model (or can be called without model at all) to render a specified view. When to use one over the other? If you already have a model and just want to have a reusable view, opt to Html.Partial . If you see that some piece deserves its own model and action, maybe it makes sense to

How can I get Html.RenderAction to call the Get method on a Post?

问题 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? 回答1: It's not a separate request happening, so it's going to use the existing request context. You may want to differentiate the action by its name, and use the ChildActionOnly attribute to mark that action as only being available via RenderAction 来源： https://stackoverflow.com/questions/3757072/how-can-i-get-html

I can easily redirect but I'd like to do a render the edit page on validation failure so I carry over all the validation methods into the form. I'm not sure how to render the edit action using active_admin. If I try render :action => 'edit' I get a template missing page I also tried render active_admin_template('edit.html.arb') which gives me a page within a page, but no errors. Any ideas? member_action :state do space = Space.find(params[:id]) if space.send(params[:state]) #space.send(params[:state]+"!") flash[:notice] = "State Changed!" redirect_to :action => :index else #render :action =>

问题 In ASP.NET MVC, what is the difference between: Html.Partial and Html.RenderPartial Html.Action and Html.RenderAction 回答1: Html.Partial returns a String. Html.RenderPartial calls Write internally and returns void . The basic usage is: // Razor syntax @Html.Partial("ViewName") @{ Html.RenderPartial("ViewName"); } // WebView syntax <%: Html.Partial("ViewName") %> <% Html.RenderPartial("ViewName"); %> In the snippet above, both calls will yield the same result.
