I'm trying to render a particular section/div click a particular link or button. Suppose link/button is in the A.cshtml page , and b.cshtml is a partial view that I want to load in A.cshtml page within a particular section/div. I tried Ajax.ActionLink but can't do. Any help or suggestions?
I tried ajaxactionlink but cant do
That's really not the way to ask a question here. Cant do is not a precise problem description. Next time when you ask a question on SO show what you have tried.
This being said, let me provide you with an example:
#Ajax.ActionLink("click me", "SomeAction", new AjaxOptions {
UpdateTargetId = "result"
})
<div id="result"></div>
and then you will have an action which will render this partial view:
public ActionResult SomeAction()
{
return PartialView("_NameOfYourPartial");
}
Finally make sure that you have referenced the jquery.unobtrusive-ajax.js script to your page which uses the HTML5 data-* attributes emitted by the Ajax.ActionLink helper to hijack the click event and send an AJAX request instead of the normal request:
<script src="#Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>
The controller can return a partial view as action result:
public ActionResult Details()
{
var model = // your model
var viewName = // your partial view name
return PartialView(viewName, model);
}
Ajax.ActionLink should do it, may be you missed somwthing.

I have a View with a Form that calls a controller action Post Method to "Complete" a Package. It then needs to refresh the page its on as that contains information that will be updated, both within the view itself and also within a partial. It does use two different Controllers in different MVC Areas.
The Post works correctly and the redirect is issued, but the page is not refreshed.
I have read that instead, I should use OnSuccess within the Ajax call that calls Complete, but I thought that was for in page calls, not ones that navigate to different pages.
View Form
#using (Ajax.BeginForm("Complete", "Packages", new { Area = "Core" },
new AjaxOptions
{
HttpMethod = "POST"
}))
{
Core(Area) Packages Controller
[HttpPost]
public ActionResult Complete(int ID)
{
// Update code
// Refresh the full page
return RedirectToAction("Summary", new { Area = "Control", id = packageBuilder.CurrentPackage.ID });
}
Control (Area) Packages Controller
[HttpGet]
public ActionResult Summary(int id)
{
// Get Model
return View("Summary", model);
}
Any pointers would be warmly welcomed.
Thanks,
Chris.
The reason that your page is not refreshed after you submit the form and the redirect is not issued in the browser, is that you are submitting the request over AJAX. This is a request issued by the browser behind the scenes.
If you want to submit the form and for the page to be refreshed, I'd recommend changing your code from Ajax.BeginForm(... to Html.BeginForm(... and then it will load the page and perform the redirect as expected.
I am not quite sure how your ajax calls are structured, but if you are using the MVC Ajax helper you can just call `location.reload(); in the OnComplete method, like so:
#using (Ajax.BeginForm(new AjaxOptions{OnComplete = "javascriptfunction"}))
{
//Data and submit button
}
<script>
function javascriptfunction(){
location.reload();
}
</script>
Am trying to get a partial view to render with an AJAX call. The following ActionResult is in my base controller which is inherited by all other controllers in the solution:
public ActionResult FileManager()
{
return View("_FileManagerPartial");
}
and the folowing code is another partial that sits on the page
#Ajax.ActionLink("File Manager", "FileManager", new AjaxOptions { UpdateTargetId = "dvFilemanagerContainer" });
dvFilemanagerContainer is a div in the layout view and the partial view "_FileManagerPartial.cshtml" is in the shared views folder.
When I click the link for the ajax call, instead of loading the intended partial view it loads a duplicate of the page into the div.
Any ideas?
Edit
PartialView contents its currently just the following
<div id="dvFilemanagerWrapper">
File Manager
</div>
change your controller to
public PartialViewResult FileManager()
{
return PartialView("_FileManagerPartial");
}
In View add this line, so that with partial view, the master layout is not rendered, only partial view is rendered:
#{
Layout = null;
}
<div id="dvFilemanagerWrapper">
File Manager
</div>
Problem was to do with how my RouteConfig was handling the call. Have created a new MapRoute to point it to the right place and is now working. Thanks for help guys.
I have a form with some controls. There is a button on the form which loads a partial view. Inside the partial view, there are two required field textboxes along with a button. And when its clicked, I need to display error messages only for textboxes which are inside the partial view, but not for the fields in the actual form. And when I click form's submit button, all error messages must show up.
After partial view is loaded, I am re-initializing the validation plugin as below.
$('#test').removeData("validator");
$.validator.unobtrusive.parse('#test');
I tried using validation attribute described in below thread but its not working. Maybe it works for normally loaded views.
ASP.NET MVC Validation Groups?
However, I can validate individually by calling textbox1.valid() and textbox2.valid(). But I think I am missing standard way of doing it. Any help is appreciated.
you can do this by submitting your partial view using Ajax.BeginForm()
//In Partail View
#model SomeModel
#using (Ajax.BeginForm("SomeActionName", new AjaxOptions { HttpMethod = "POST", UpdateTargetId = "targetId"}))
{
#Html.EditorFor(mode=>model.FirstText)
#Html.EditorFor(mode=>model.SecText)
<input type="submit" value="save">
}
//In Controller
public ActionResult SomeAction(SomeModel model)
{
return PartaiulView(model);
}
here you can validate your Partial View
NOTE: when you submit you form using Ajax.BeginForm you must specify "UpdateTargetId" where your result will be appear on View.
//In View
<div id="targetId">
#Html.Partail("PartialView")
</div>
OR if you want to Redirect to another action if your model is valid then modified your action
public ActionResult SomeAction(SomeModel model)
{
if(ModelState.IsValid)
{
return Json(new {redirect = #Url.Action("SomeAction","SomeController")})
}
return PartaiulView(model);
}
then in partail view you can invoke OnSuccess method of Ajax.BeginForm
#using (Ajax.BeginForm("SomeActionName", new AjaxOptions { HttpMethod = "POST", UpdateTargetId = "targetId",OnSuccess="success"}))
{
}
<script type="text/javascript">
function success(data)
{
if(data.redirect)
{
windows.location = data;
}
}
</script>
check both way which one is suitable to you.
I have a button. After first click I am getting "Button pressed!" confirmation message. When I press button again I am getting confirmation twice. After third press, message appears four time. In fact I am getting geometric progression. Please help.
View is.
#{
ViewBag.Title = "Home";
<script src="#Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>
}
<div id="buttonPressed">
#Ajax.ActionLink("Button", "Index", new AjaxOptions { Confirm = "Button pressed!", UpdateTargetId = "buttonPressed" })
</div>
Controller is.
public class HomeController : Controller
{
public ActionResult Index()
{
return View();
}
}
When the post comes back you are replacing the contents of the buttonPressed div which contains the button itself. Not a great thing to do.
In addition it is not proper to call back to the Index method which originally displayed the view. That will re-render the page along with the html in the div with an entire rerendering of the view (including all master page stuff), which will continue to happen over and over again.
You need to change the action callback to another action method in your controller, then return a partialView of some html or a string or something else.
I have a View with url like
/Home/SetResults?patientId=[somePatientId]
, part of it gets conditionaly ajax-updated with some partialview
Inside of that partialView I have this code
<% using (Ajax.BeginForm("Action", "Home", new AjaxOptions { UpdateTargetId = "placeholder", InsertionMode = InsertionMode.Replace,HttpMethod = "Post"}))
{%>
<div id="placeholder">
....
Whenever I press submit button I get to my simple controller action-method
[HttpPost]
public ActionResult Action(MyModel model)
{
return PartialView();
}
Everything works fine except the ajax itself - instead of gettin my placeholder updated with the result of controller action I'm always getting redirect to a view with the url of
/Home/Action
So, is it possible to partially update partial view? If yes what I'm doin wrong?
One thing to check would be that you are including the ajax script:
<script src="#Url.Content("~/Scripts/jquery.unobtrusive-ajax.min.js")" type="text/javascript"></script>
I've noticed if this isn't included, submitting the Ajax form behaves like a regular submit.
