Id not getting passed to Partial View form

Parent View:
#Html.Action("SetReview", "Review", new {sellerId = Model.SellerId})
[HttpGet]
public ActionResult SetReview(string sellerId)
{
return PartialView("_Review", new Finder.Models.Review()
{
SellerId = sellerId
});
}
This is the part where the Id is not getting passed
[HttpPost]
public ActionResult SetReview(Finder.Models.Review review)
{
var review2 = new Review()
{
PersonId = User.Identity.GetUserId(),
SellerId = review.SellerId,
Rating = review.Rating,
IsAnonymous = review.IsAnonymous,
CreatedOn = DateTime.UtcNow,
Content = review.Content,
};
DbContext.Reviews.Add(review2);
DbContext.SaveChanges();
return Json(new { status = "true", msg = "Successfully processed" });
}
No idea what's going wrong here. Shouldn't the get function pass the model to the post one, and the review.Id not get lost?

SellerId actually is in get method when you call get method and u see your view seller id is null bcos your not post it you need seller id in your post method just it !

Try the below code it will hit your post method
#using Finder.Models
#model Review
<form asp-controller="Review" asp-action="SetReview" method="post">
<div class="panel-group">
<div class="panel panel-default">
<div class="panel-body">
#Html.Action("SetReview", "Review", new {sellerId = Model.SellerId})
</div>
<div class="col-12">
<button type="submit" name="save" class="btn bg-blue"><i class="fa fa-floppy-o"></i>Save</button>
</div>
</div>
</div>
</form>

Working with multiple partial views

Good day
I am working with 7 partial views on my index page.
Index.cshtml (code section that creates the partial views in their own tabs)
#model project1.Models.MasterModel
<div class="tab-content col-lg-9 col-md-9 col-sm-9 col-xs-9" style="margin-bottom:110px;">
<div id="partial1" class="tab-pane fade in active">
#Html.Partial("partial1", Model)
</div>
<div id="partial2" class="tab-pane fade in">
#Html.Partial("partial2", Model)
</div>
<div id="partial3" class="tab-pane fade in">
#Html.Partial("partial3", Model)
</div>
<div id="partial4" class="tab-pane fade in">
#Html.Partial("partial4", Model.Owners)
</div>
<div id="partial5" class="tab-pane fade in">
#Html.Partial("partial5", Model)
</div>
<div id="partial6" class="tab-pane fade in">
#Html.Partial("partial6", Model)
</div>
<div id="partial7" class="tab-pane fade in">
#Html.Partial("partial7", Model)
</div>
On partial1 I have a submit button that should populate the other partial views with the information that is submitted on the first partial view.
My Model consist of 7 models (one for each partial view)
MasterModel.cs
public class MasterModel
{
public DisplayPartial1 view1 {get;set;}
public DisplayPartial2 view2 {get;set;}
public DisplayPartial3 view3 {get;set;}
public DisplayPartial4 view4 {get;set;}
public DisplayPartial5 view5 {get;set;}
public DisplayPartial6 view6 {get;set;}
public DisplayPartial7 view7 {get;set;}
}
In my controller's Index Action result I create a new instance of the MasterModel and then I create new instances for all the sub models and return to the Index view.
MainController.cs
// Global variable used and returned by all partial views
MasterModel main = new MasterModel();
public ActionResult Index()
{
MasterModel master = new MasterModel();
master.view1 = new DisplayPartial1 ();
master.view2 = new DisplayPartial2 ();
master.view3 = new DisplayPartial3 ();
master.view4 = new DisplayPartial4 ();
master.view5 = new DisplayPartial5 ();
master.view6 = new DisplayPartial6 ();
master.view7 = new DisplayPartial7 ();
return View(master);
}
public ActionResult MyPartial1()
{
return PartialView("MyPartial1", master);
}
[HttpPost]
public ActionResult MyPartial1(MasterModel model, string submitButton)
{
if(submitButton == "GetInfo")
{
/*Process input values*/
//wcf service return data
main.view1.id = serviceObject.Id;
...
main.view4.name = serviceObject.Name;
...
}
return PartialView("MyPartial1", master);
}
When MyPartial1 is returned then the other 6 partial view do not update with the assigned information until I do a submit call with a java script that looks like the following:
<script type="text/javascript">
$(document).ready(function () {
$('#input1').change(function () {
$('form').submit();
});
$('#input2').change(function () {
$('form').submit();
});
});
</script>
An Example Partial view (all the partial views work on the same principals)
#model OperatorLicense.Models.MasterModel
#using (Ajax.BeginForm("MyPartial1", "Operator", null, new AjaxOptions
{
UpdateTargetId = "MyPartial1",
InsertionMode = InsertionMode.Replace,
HttpMethod = "Post"
}, new { id = "MyPartial1" }))
{
#Html.TextBoxFor(model => model.view1.SerialNumber, new { id="SerialNumber", #class = "form-control", placeholder = Html.DisplayNameFor(n => n.view1.SerialNumber) })
...
}
Is there a way to refresh the other partial views when the MyPartial1 partial view has returned so that the assaigned values can be displayed on the required partial view?

You can use OnSuccess or OnComplete property of AjaxOptions class.
#using (Ajax.BeginForm("MyPartial1", "Operator", null, new AjaxOptions
{
UpdateTargetId = "MyPartial1",
InsertionMode = InsertionMode.Replace,
HttpMethod = "Post",
OnSuccess="partial1Success"
}, new { id = "MyPartial1" }))
{
#Html.TextBoxFor(model => model.view1.SerialNumber, new { id="SerialNumber", #class = "form-control", placeholder = Html.DisplayNameFor(n => n.view1.SerialNumber) })
...
}
define partial1Success method in javascript
<script type="text/javascript">
function partial1Success(){
// write your other partial view refresh logic here
}
</script>
partial1Success method called after from submit successfully.

Model passed to Partial to View

Been searching around but couldn't find a direct solution to what I'm trying to achieve.
I've tried to include as much as needed but it's a very large project so hopefully you'll get the gist.
Overview:
I have a view model that has several lists of objects within it. I am using two partial views for control over each of the list of objects, one for gathering the list of objects (which is held in a session), and the other for adding a list of said object into the list.
Update:
As per comment - what I am looking to do is as follows - in the Index, fill out the existingIp model info, which is displayed through the addToListPartialView, then it will post to the ListPartialView to update the list through the session, handled backend in the controller, which will in turn display on the Index - the question ultimately is, how do I achieve this?
Problem:
The issue I'm having is once I've added an object, through a partial view, to the object list, another partial view, how do I then pass this back to the main view?
Code:
Controller
public ActionResult AddExistingIp([Bind(Include = "Subnet, Cidr, Mask")]ExistingIp existingIp)
{
if(Session["pa_ipv4Session"] != null)
{
pa_ipv4 pa_ipv4 = (pa_ipv4)Session["pa_ipv4Session"];
if(pa_ipv4.ExistingIps == null)
{
pa_ipv4.ExistingIps = new List<ExistingIp>();
}
pa_ipv4.ExistingIps.Add(existingIp);
ViewBag.pa_ipv4 = pa_ipv4.ExistingIps;
return View("ExistingIpView", ViewBag.pa_ipv4);
}
else
{
pa_ipv4 pa_ipv4 = new pa_ipv4();
Session["pa_ipv4Session"] = pa_ipv4;
pa_ipv4.ExistingIps = new List<ExistingIp>();
pa_ipv4.ExistingIps.Add(existingIp);
ViewBag.pa_ipv4 = pa_ipv4.ExistingIps;
return View("ExistingIpView", ViewBag.pa_ipv4);
}
Index:
#model ViewModel
<div id="ExistingIpList">
#{Html.RenderPartial("ExistingIpView");}
</div>
<div id="addExisting">
#{Html.RenderPartial("AddExistingIp");}
</div>
List Partial
#model IEnumerable<ExistingIp>
#if (Model != null)
{
foreach (var ei in Model)
{
<div class="ui-grid-c ui-responsive">
<div class="ui-block-a">
<span>#ei.Subnet</span>
</div>
<div class="ui-block-b">
<span>#ei.Cidr</span>
</div>
<div class="ui-block-c">
<span>#ei.Mask</span>
</div>
<div class="ui-block-d">
#ei.Id
Delete
</div>
</div>
}
}
Add to list partial:
#using (Html.BeginForm("AddExistingIp", "PA_IPV4"))
{
<div class="ui-grid-c ui-responsive">
<div class="ui-block-a">
<span>
#Html.EditorFor(m => m.Subnet)
#Html.ValidationMessageFor(m => m.Subnet)
</span>
</div>
<div class="ui-block-b">
<span>
#Html.EditorFor(m => m.Cidr)
#Html.ValidationMessageFor(m => m.Cidr)
</span>
</div>
<div class="ui-block-c">
<span>
#Html.EditorFor(m => m.Mask)
#Html.ValidationMessageFor(m => m.Mask)
</span>
</div>
<div class="ui-block-d">
<span>
#Html.EditorFor(m => m.Id)
#Html.ValidationMessageFor(m => m.Id)
</span>
</div>
</div>
<div data-role="main" class="ui-content">
<div data-role="controlgroup" data-type="horizontal">
<input type="submit" id="addExistingIp" cssclass="ui-btn ui-corner-all ui-shadow" value="Add" />
</div>
</div>
}
ViewModel:
public Contact ContactDetails { get; set; }
[Required]
public bool ExistingAddress { get; set; }
public List<ExistingIp> ExistingIps { get; set; }
[Required]
[DataType(DataType.MultilineText)]
public string ExistingNotes { get; set; }

You can modify the AddExistingIp to just store the data. And to make a RedirectToAction Index. There you will take the data from Session and pass it to the Model.
[HttpPost]
public ActionResult AddExistingIp([Bind(Include = "Subnet, Cidr, Mask")]ExistingIp existingIp)
{
if(Session["pa_ipv4Session"] != null)
{
pa_ipv4 pa_ipv4 = (pa_ipv4)Session["pa_ipv4Session"];
if(pa_ipv4.ExistingIps == null)
{
pa_ipv4.ExistingIps = new List<ExistingIp>();
}
pa_ipv4.ExistingIps.Add(existingIp);
}
else
{
pa_ipv4 pa_ipv4 = new pa_ipv4();
Session["pa_ipv4Session"] = pa_ipv4;
pa_ipv4.ExistingIps = new List<ExistingIp>();
pa_ipv4.ExistingIps.Add(existingIp);
}
return RedirectToAction("Index");
}
The Index Action will look similar with this, where you take data from Session and use it in your Model
public ActionResult Index()
{
var viewModel = new ViewModel();
// take data from Session
pa_ipv4 pa_ipv4 = Session["pa_ipv4Session"] as (pa_ipv4);
// some verification
// add the list from Session to model
viewModel.ExistingIps = pa_ipv4.ExistingIps;
return View(viewModel);
}
Also, I think your Index View you should at ExistingIpView you should pass the Model to display.
#model ViewModel
<div id="ExistingIpList">
#{Html.RenderPartial("ExistingIpView", Model.ExistingIps);}
</div>
<div id="addExisting">
#{Html.RenderPartial("AddExistingIp");}
</div>

Passing multiple Collections of data from View to Controller (ASP.NET MVC 5)

In a View i have the next structure ( control of Subject*s for each *Group):
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
<div class="form-horizontal">
#for (int i = 0; i < ViewBag.AllGroups.Count; i++)
{
<h4>#ViewBag.AllGroups[i].Code</h4>
<select id="e-#i" multiple="multiple">
#foreach (Subject subject in ViewBag.AllSubjects)
{
<option value="#subject.Name">#subject.Name</option>
}
</select>
}
<input type="submit" value="Generate" class="btn btn-default" />
</div>
}
The question is that how can I retreive this data (I want to receive (1)list of Groups and and I want to get a (2)list of all selected Subjects for each group in my list(1)) in my Controller?
Thank you in advance.

Recommended way is to use strongly typed View Model Object
public class GroupViewModel
{
public string Code { get;set; }
public List<Subject> AllSubjects { get; set; }
}
Pass List as the Model to the Razor view in the controller.
return new View(new List<GroupViewModel>()); // populated one.
Use this list in the View.
#model IList<GroupViewModel>
#for (int i = 0; i < Model.Count; i++)
{
<h4>Model[i].Code</h4>
<select id="e-#i" multiple="multiple">
#foreach (Subject subject in Model[i].AllSubjects)
{
<option value="#subject.Name">#subject.Name</option>
}
</select>
}

There is nothing especial to deal with this situation, except that you have missed the tag name of the select element.
To be exact, all html elements such as select you have used here, should have a name not id (id="e-#i") and all elements are serialized based their names and sent to server. On the other side, at server-side, you should get the posted values which are in a csv formatted (due to multiple ability added you have added to select element)

Solved my problem by simplifying the task. What i had to to: I created new ViewModel for this thing. I replaced tag <select></select> with #Html.ListBoxFor(m => m.Subjects, Model.SubjectItems). I had to create a SubjectItems list in my ViewModel.
Here's the code (Sorry for tons of code: I just want to make everything clear):
My View:
#using System
#using System.Linq
#using TimeTable.GenericRepository
#model TimeTable.Models.GroupViewModel
#{
//it's better to move the next line to a Controller later
ViewBag.GroupId = new SelectList(new GroupRepository().Get().ToList(), "Id", "Code", Model.GroupId);
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_LayoutBootstrap.cshtml";
}
<h2>Index</h2>
<hr />
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
<div class="form-horizontal">
#Html.ValidationSummary(true)
<div class="form-group">
#Html.LabelFor(model => model.GroupId, "Group is: ", new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.DropDownList("GroupId", String.Empty)
#Html.ValidationMessageFor(model => model.GroupId)
</div>
</div>
#Html.ListBoxFor(m => m.Subjects, Model.SubjectItems, new { #id = "e", #style = "width:80%; " })
<br /><br />
<input type="submit" value="Generate" class="btn btn-default" />
</div>
}
#* ReSharper disable once Razor.SectionNotResolved *#
#section Scripts {
#Styles.Render("~/Content/select2")
#Scripts.Render("~/bundles/select2")
<script type="text/javascript">
$(function () { $("#e").select2(); });
</script>
}
My Controller:
public ActionResult Generate()
{
return View(new GroupViewModel());
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Generate(GroupViewModel gvm)
{
var subjects= gvm.Subjects; // <== selected subjects are here
return View();
}
My Model:
public class GroupViewModel
{
public int GroupId{ get; set; }
public Group Group {
get { return new GroupRepository().GetById(GroupId); }
}
public object Subjects { get; set; }
public IEnumerable<SelectListItem> SubjectItems
{
get
{
var items = new SelectList(new SubjectRepository().Get().ToList(), "Id", "Name");
return items;
}
}
}
P.S. Select2 is a custom replacement for selectBoxes, it's not necessary, but I like it: http://ivaynberg.github.io/select2/

Partial View to Add Data

So here, I need to add comment for video in one view.
I have the main view code like this that displaying video and comment for that video.
<!-- language: C# -->
#model AzureMediaPortal.ViewModels.ViewModelWatch
#{
ViewBag.Title = "Watch";
}
<div id="videoPlayer">
</div>
<h2>#Html.DisplayFor(model => model.media.Title)</h2>
<h3> By #Html.DisplayFor(model => model.media.UserId) at #Html.DisplayFor(model => model.media.UploadDate) </h3>
#Html.HiddenFor(model => model.media.Id)
#Html.HiddenFor(model => model.media.AssetId)
#Html.HiddenFor(model => model.media.FileUrl, new { id = "fileUrl" })
<div class="display-label" style="font-weight:bold">
#Html.DisplayNameFor(model => model.media.Description)
</div>
<div class="display-field">
#Html.DisplayFor(model => model.media.Description)
</div>
<br />
<div class="display-label" style="font-weight:bold">
#Html.DisplayName("Category")
</div>
<div class="display-field">
#Html.DisplayFor(model => model.media.Category.CategoryName)
</div>
<h3>Comments</h3>
#foreach (var item in Model.comment)
{
<div class="display-label" style="font-weight:bold">
#item.UserId
</div>
<div class="display-field">
#item.Content
</div>
}
#Html.Partial("Post",new AzureMediaPortal.ViewModels.ViewModelWatch())
#section Scripts {
<script src="~/Scripts/playerframework.min.js"></script>
<script src="~/Scripts/media-player.js"></script>
#Scripts.Render("~/bundles/jqueryval")
<script type="text/javascript">
mediaPlayer.initFunction("videoPlayer", $("#fileUrl").val());
</script>
}
and this the partial view
#model AzureMediaPortal.ViewModels.ViewModelWatch
#{
ViewBag.Title = "Post";
}
<h2>Add Comment</h2>
#Html.HiddenFor(model => model.cmnt.MediaElement.Id)
#using (Html.BeginForm("Post","Home",FormMethod.Post)) {
#Html.AntiForgeryToken()
#Html.ValidationSummary(true)
<fieldset>
<legend>Add Comment</legend>
<div class="editor-label" style="font-weight:bold">
#Context.User.Identity.Name
</div>
<div class="editor-field">
#Html.TextAreaFor(model => model.cmnt.Content)
#Html.ValidationMessageFor(model => model.cmnt.Content)
</div>
<p>
<input type="submit" value="Post" />
</p>
</fieldset>
}
#section Scripts {
#Scripts.Render("~/bundles/jqueryval")
}
this is my ViewModel
public class ViewModelWatch
{
public MediaElement media { get; set; }
public List<Comment> comment { get; set; }
public Comment cmnt { get; set; }
}
and this is my controller
public ActionResult Watch(int id)
{
ViewModelWatch vm = new ViewModelWatch();
vm.media = _repository.GetMedia(id);
vm.comment = _repository.GetMediaComment(id);
return View(vm);
}
public ActionResult Post()
{
return View();
}
[HttpPost]
public ActionResult Post(Comment comment, int id)
{
if (ModelState.IsValid)
{
comment.UserId = User.Identity.Name;
comment.MediaElement.Id = id;
db.Comments.Add(comment);
db.SaveChanges();
return RedirectToAction("Watch");
}
return View();
}
I need to pass data from partial view and save it to database include the media.Id to know that comment inserted for the video.
Thanks so muchhh

putting scripts on a partial view is generally bad practice. Script gets inserted into the middle of the view. For saving information from a partial view I use ajax calls. To do that add a class to your post button
<input type="button" class="btnSubmit" value="Post" />
then in your script on the main page
$(document).on('click', '.btnSubmit', function(){
$.ajax({
url: '#Url.Action("Action", "Controller")',
cache: false,
async: true,
data: {
//put the data that you want to save from the partial here
id: $('#hiddenID').val(),
content: $('#Content').val()
},
success: function (_result) {
//can add something here like an alert, close a popup something along those lines
}
});
});
just make sure the inputs on your controller match exactly the names that you have defined here
[HttpPost]
public ActionResult Action(int id, string content){
//database call to save the fields
//see here for an example of returning json http://stackoverflow.com/questions/1482034/extjs-how-to-return-json-success-w-data-using-asp-net-mvc
return Json(json);
}

I would suggest using #Html.Action and get the create form from there. Also, once the comments are stored you can redirect to the parent action. That should automatically update the comments list.
But that would be a bad idea.
Rather you can put get your comments by calling action from ajax ($.ajax) and use pure.js to replace the older ones with the new comment list.
