I have this contact form which I want to use on two pages (two views) in MVC 5.x (razor viewengine) So I have put the form in an partialview called _Contact and I have read that RenderAction is the best approach if you do not have the required data for the partialview in your model and if it is more standalone (seperate from the rest of the view)
So I call it like this:
#{ Html.RenderAction("SendMail", "Uk");}
My Uk controller has these two methods:
[HttpGet]
public PartialViewResult SendMail()
{
return PartialView("_Contact");
}
[HttpPost]
public PartialViewResult SendMail(FormCollection fc)
{
// send mail using values out of the form (sorry did not feel like building a complete model for it
ViewBag.Succeed = true;
// if smtpclient could not reach server etc. it returns false
return PartialView("_Contact");
}
it all works, but the PartialView is only rendered, not on the placeholder where i call the RenderAction. It works all great, but after the post it just displays the partial view and not the "parent view" and the shared layout view etc. I hope that I made myself clear. Please let me know if I need to add more info.
This is the BeginForm from my shared view:
using (Html.BeginForm("SendMail", "Uk", FormMethod.Post))
It will not work as expected for your current code, because when you post the form, it returns Partial View not complete View. If you want to get only partial view then you have to submit your form via Ajax.
In ajax's success handler you will get HTML of your partial view and that you can put in a DIV tag of partial view container.
This link will give you a better idea about Posting Partial View via Ajax.
ASP.NET MVC Partial view ajax post?

I'm very new to MVC and I am looking to put a list of links on the main layout(master page) based on database table. I'm sure I read before that you shouldn't try to load models on the master page but use Partial Views instead (correct me if I'm wrong).
I've looked on Google and on other questions here but they only seem to talk about passing data from a main view to a partial view via ViewBag but I think I just want to add a partial view that I can add to the master page.
Can someone please tell me how to create a partial view I can add to master page so its used on every page and be able to load the list of links required i.e. by binding IEnumerable model to Partial View?
Try using ChildActionExtensions.Action
In your layout:
#Html.Action("MyAction", "MyController")
Controller:
public ActionResult MyAction()
{
var list = // get your list values
return PartialView("MyViewName", list);
}
Then just create your partial view:
#model IEnumerable<WhateverType>
#* View goodness *#
You can use this to bind whatever model you need to your partial view and if you use the Action helper in your Layout.cshtml it'll be rendered on every page.
I have a viewpage and a partialview on that. For default request-when page is called- CultureInfo is set in base class of viewPage. I have created this custom base class which initialize the culture depending on a cookie and does some other stuff as well. There is a search button on the view page which updates a partial view on the page with Ajax call (jquery Ajax call). There is separate action for this partial view update call which returns partial view. The problem is partial view do not have any base class and when resources are displayed on partial view they are displayed for default culture and not the current culture. What would be best approach to set cultureInfo when partial view is called from jQuery Ajax call?
I have this mvc application as part (area) of bigger existing application so I can not touch session_start.
I'm not sure why you need to pass the culture around, can't you get it directly from your PartialView using a helper method?
#YourApp.CultureHelper.GetCurrentCulture()
which is just calling
public static string GetCurrentCulture()
{
return Thread.CurrentThread.CurrentCulture.Name;
}
If you are doing any work with internationalization and ASP.NET MVC I highly recommend reading through these two excellent posts by Nadeem Afana
ASP.NET MVC 3 Internationalization
ASP.NET MVC 3 Internationalization - Part 2 (NerdDinner)
Very well written and explains everything you need to know about internationalization.
You can send the culture info to your partial view as model with string array.
I guess you have handled the ajax call so I am just gonna show you the way of passing the value. The below one is your controller :
public ActionResult Index() {
return PartialViewResult("samplePartial", new string[] { "en" });
}
And this is your partial view :
#model string[]
#if(Model[0] == "en") {
#:Culture is "en"
} else {
#Culture is different than "en"
}
Also this can be also rendered inside your view as indicated below :
#Html.Partial("samplePartial", new string[] { "en" })
How can I pass parameters to a partial view in MVC3 (razor). I replaced a regular View page with a Partial View in my MVC project. For a regular View page, I passed parameters like
public ActionResult MeanQ(int id)
{
Access access= db.Access.Find(id);
return View(access);
}
Now since I changed the view to a partial view, I have the following code instead:
public ActionResult MeanQ(int id)
{
Access access= db.Access.Find(id);
return PartialView("_MeanQPartial");
}
but do not know how I can still pass the parameter 'id' to make it work like before. Please help. For what its worth, the View or the partial View , both are triggered by a link and displayed in a Jquery Modal Dialog box.
Try this
return PartialView("PartialViewName", access);
Simply give it as 2nd parameter. PartialView method has 4 overloads and this includes one with two parameters PartialView(string viewName, object model)
public ActionResult MeanQ(int id)
{
Access access= db.Access.Find(id);
return PartialView("_MeanQPartial", access);
}
For what its worth, the View or the partial View , both are triggered by a link and displayed in a Jquery Modal Dialog box.
View would return an entire page using your layout. PartialView only returns the HTML from your partial. For a modal dialog, the partial is enough. No need to retrieve a complete page.
I have a partial view that shows a list of Categories. I'd like to put that partial view on any page, but I'd like to have it to call to the service and get a list of categories by itself without me having to do that in every controller action. Something like webforms in which you can put a code-behind on it.
For eg.
Actions
public ActionResult Index()
{
JobListViewModel model = new JobListViewModel();
model.Categories= jobService.GetCategories();
return View(model);
}
public ActionResult Details(int id)
{
Job job = jobService.GetJob(id);
return View(job);
}
I created a partial that will take the model.Categories model and display a list. As you can see, the Index page will work fine, but I do not want to call it again in the Details page. Is there a way to make my partialview call to the GetCategories() service by itself?
Use Html.RenderAction - that gives the partial view its own controller action.
You should also mark you partial action with the attribute [ChildActionOnly].
DVark,
As noted in the accepted answer, for your scenario, RenderAction is the most appropriate.
I thought I'd link a little article that distils my thinking on the topic (i.e. when to use RenderPartial vs RenderAction):
http://cbertolasio.wordpress.com/2010/09/21/mvc-html-renderaction-vs-html-renderpartial/
hope it helps
[edit] - as an aside. a year or so ago, i got myself into a few scrapes by not appreciating the power of RenderAction, in favour of RenderPartial. as a result, i had littered the shared view space with lots of partialviews in order to access them from a variety of sources. the moral of the story: know your 'territory' before planting your flag.
I'm loading a partial view with an AJAX call:
public ActionResult LoadServerForm()
{
//data stuff
ViewData["ApplicationID"] = appID.ToString();
ViewData["Servers"] = ServersList(appServerRep.Session, null, appServers);
return PartialView("Application_AddServer");
}
This works great, but I'm trying to get away from magic ViewData strings. I tried making the partial view inherit from the same ViewModel as the "hosting" page, but the Model object is null when I try to this in the partial view:
<%= Html.HiddenFor(model=>model.Application_Key, Model.Application_Key) %>
Is there a way to pass the main page ViewModel down into the AJAX-loaded PartialView or should I be looking for a different approach altogether?
When you return PartialView("Application_AddServer");, you have to pass the model:
return PartialView("Application_AddServer", model);
Since this is an AJAX request, it's a separate controller action invocation, and the new PartialView doesn't know about the model of the requesting page. You'll have to reconstruct it, either from whatever your original data source is or from data passed with the AJAX request.
