In ASP.NET MVC, what is the difference between:
Html.Partial
and Html.RenderPartial
Html.Action
and Html.
The return type of Html.RenderAction
is void
that means it directly renders the responses in View where the return type of Html.Action
is MvcHtmlString
You can catch its render view in controller and modify it by using following method
protected string RenderPartialViewToString(string viewName, object model)
{
if (string.IsNullOrEmpty(viewName))
viewName = ControllerContext.RouteData.GetRequiredString("action");
ViewData.Model = model;
using (StringWriter sw = new StringWriter())
{
ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(ControllerContext, viewName);
ViewContext viewContext = new ViewContext(ControllerContext, viewResult.View, ViewData, TempData, sw);
viewResult.View.Render(viewContext, sw);
return sw.GetStringBuilder().ToString();
}
}
This will return the Html string of the View.
This is also applicable to Html.Partial
and Html.RenderPartial
