I thought this was going to be straight forward but I managed to hose it up some how. If I want to pass URL parameters to another action do I have to create a new route for that?
controller
[ChildActionOnly] public ActionResult ContentSection(string sectionAlias, string mvcController, string mvcAction = null) view
@Html.RenderAction("ContentSection", "Portal", new {sectionAlias = "TermsAndConditions", mvcController = "Portal", mvcAction = "ChoosePayment"}) error
CS1502: The best overloaded method match for 'System.Web.WebPages.WebPageExecutingBase.Write(System.Web.WebPages.HelperResult)' has some invalid arguments

The difference between the two is that Html. RenderAction will render the result directly to the Response (which is more efficient if the action returns a large amount of HTML) whereas Html. Action returns a string with the result.
RenderAction(HtmlHelper, String, String, RouteValueDictionary) Invokes the specified child action method using the specified parameters and controller name and renders the result inline in the parent view.
A render action is a public method on the controller class. You can define a render action method to return any data, but you can only safely use it if it returns an HTML markup string.
The problem here is that
@Html.RenderAction("ContentSection", "Portal", new {sectionAlias = "TermsAndConditions", mvcController = "Portal", mvcAction = "ChoosePayment"}) Is the equivalent to
<%= Html.RenderAction("ContentSection", "Portal", new {sectionAlias = "TermsAndConditions", mvcController = "Portal", mvcAction = "ChoosePayment"}) %> In the the Webforms ViewEngine (which is also the same a Response.Write). Since RenderAction returns void, you cannot Response.Write it. What you want to do is this:
@{ Html.RenderAction("ContentSection", "Portal", new {sectionAlias = "TermsAndConditions", mvcController = "Portal", mvcAction = "ChoosePayment"}); } The @{ } syntax signifies a code block in the Razor view engine, which would be equivalent to the following the the Webforms ViewEngine:
<% Html.RenderAction("ContentSection", "Portal", new {sectionAlias = "TermsAndConditions", mvcController = "Portal", mvcAction = "ChoosePayment"}); %> If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
