I'm wondering if there is a good way to do this. I'm currently trying to send some temporary data to multiple partial views being called from the same view page in my MVC application.
I'm currently attempting to do this with TempData but I can see my understanding is limited as it is only going through for one partial request. What method do I need to use to filter out to all of my partials?
Main View Page:
#{
ViewBag.Title = "Main View Page";
TempData["ReturnUrl"] = Request.Url.OriginalString.ToString();
}
#Html.Partial("_StatusTable1")
#Html.Partial("_StatusTable2")
#Html.Partial("_StatusTable3")
#Html.Partial("_StatusTable4")
#Html.Partial("_StatusTable5")
Partial View Example:
#{
var temp = TempData["ReturnUrl"]; // temp is null on all partials except the first
}
// Partial View Code ...
Thanks in advance.
In your main view page call the partiel views like that
#Html.Partial("_SomePartial", TempData["ReturnUrl"])
I think that even this would work.
#Html.Partial("_SomePartial", TempData)
Get the value from TempData like this. ReturnUrl Value will retained across all the Partial Views
#{
var temp = TempData.Peek("ReturnUrl");
}
// Partial View Code

Hi I have a partial view setup for handling error messages, but when it's returned it returns a full webpage with just the text No Results Found.
I would expect the Partial View to return inline on my main Index page? As in my Index page I have the code #Html.Partial("_ErrorMessage").
Below is how I'm handling this in my HomeController
else
{
ViewBag.Error = "No results found!";
return PartialView("ErrorMessage");
}
}
Partial view not necessary return html inline. Partial view can return html inline if you call by client script, using jquery, angular, etc.
This way did you make. The return is a whole page.
Context is important here. If you are including the partial view in line in the HTML, you probably don't need to return the partial view in C-sharp unless you're using a fancy asynchronous call to load it.
The in-line partial view should display normally if you just show the view where it was included
I am not sure what the exactly error you are facing but you can try following solution, you have to set Layout as null after you will not facing the full page on your partial view.
#{
Layout = null;
}
If you are not using Layout=null it will call your _Layout page.
Hope it helps you.
I have a index.cshtml page and index2.cshtml partial page in my file location of Views/Index/. I want to pass data from index.cshtml to index2.cshtml without using link, don't look in page.
For example:
index.cshtml:
#{
ViewBag.data = 1;
#Html.Partial("index2")
}
index2.cshtml(partial):
#ViewBag.data
Preview of index.cshtml is : 1
If you're using a partial to show index2 then your viewbag/viewdata should persist to the partial but if not you can pass the view data in the renderpartial method
#Html.RenderPartial("index2", Html.ViewData)
I want to show a view on some of my forms, which shows a list of alerts, read from a database table. I think I need to use a partial view - but haven't used one.
So far, I created a partial view in my shared views folder called "_Alerts.cshtml".
In that file, at the moment, I simply have:
#{
Layout = null;
}
This is a shared view.
This is just me trying to display something.
And then, on my existing page, on which I want to display the alerts, I have this section of code:
#if (User.Identity.IsAuthenticated)
{
<div class="row">
#Html.Partial("~/Views/Shared/_Alerts.cshtml", null)
</div>
}
This works. However, my understanding is not right. At the moment, I pass no model to it. Is there no controller for the partial view? At the moment, I need to create a controller method - somewhere - that gets me a list of alerts from my data service, and then I want to format that and present it in the partial view. But I am unsure where the controller methods go. If this view is called from 8 different screens, would the 8 controllers for these screens have a call to get my alerts, and format them?
Seems like a lot of duplication.
They need not be duplication.
You can define the action you want inside a controller and call #Html.Action instead of #Html.Partial
Inside you action you can return a partial view.
public class AlertsController : Controller
{
public ActionResult Show()
{
var model = GetModel();//decide where this will come from.
return PartialView("~/Views/Shared/_Alerts.cshtml",model);
}
}
In your layout view or wherever you need to use it. you can simply call it as below.
#Html.Action("Show","Alerts")
If you have all the data you need to pass into the partial, then you can use the #Html.Partial and pass in the model.
If on the other hand, you want the view you are embedding to get the data itself, then you would use Html.RenderAction
I created some views in visual studio by clicking right click=> add => view.
I select in the selection: "use a layout or master page".
Now I want to turn these views to partial views should I delete it and create new? or I can somehow turning it to partial view without deleting the views?
In Razor there is no much difference in View and partial view
Only difference is
#{
Layout = "~/Views/Shared/_Layout.cshtml";
}
If there is no layout specified they could be considered as partial views.
From your controller action you return PartialView(); instead of return View(); this layout will not be applied.
I am trying to dynamically render pages from database. The view looks like this
#model MyModel
#{
ViewBag.Title = Model.Title;
Layout = Layout = "~/Views/Shared/_PageInnerLayout.cshtml";
}
#MvcHtmlString.Create(Model.Content)
MyModel has just 3 properties; Id, Title and Content
If the Content has just HTML, the view renders just fine. But in some cases, I need to render partials too. So Content may contain code like
#{
Html.RenderPartial("_FooterPartial");
}
This does not work. Its being rendered literally, like shown in the image below
How do I fix this so that the page is rendered properly?
The problem is in the difference between Html.RenderPartial and Html.Partial helper methods. RenderPartial directly write the result to HttpContext.Response while Partial return it as a MvcHtmlString. You need to replace the RenderPartial with Partial and maybe the RenderAction with Action.
Edited:
You need to render the content if contains the razor view scripts. If so it means you are actually storing the views or partial views inside the database. You can create a new VirtualPathProvider to help loading the views from the database. For more information see ASP.NET MVC load the Razor views from database and ASP.NET MVC and virtual view
I tried doing this with VirtualPathProvider, but it didn't work.
Finally what I did was to write the Content from database into a temporary view and then render the view. It worked
public ActionResult DynamicPage(int id) {
var dynamicPage = new PagesContext().Pages.FirstOrDefault(s => s.Id == id);
string webroot = Server.MapPath("~").TrimEnd('\\');
string fileName = webroot + "\\Views\\\\Solutions\\Temp.cshtml";
System.IO.File.WriteAllText(fileName, dynamicPage.Content);
return View("Temp");
}
Here, the Content property of the dynamicPage containts HTML(including Razor code)
