I have setup an httppost that sends a string into my controller, searches for some results using linq, and then sends the results to a view. In debug stepping through the code I can see the data that I am looking for being passed into the return view statement, but the page just appears to refresh (it doesn't render the view as expected with the result). why my controller fails to redender the view? (note: I didn't include the view because I can send a ToList() to it without an issue. For example, return View(_entities.Persons.ToList());
[HttpPost]
public ActionResult RenderSearch(string usersearchtext)
{
if (usersearchtext != null)
{
var search_results = from s in _entities.Persons
where s.Description.Contains(usersearchtext)
select s;
return View("SearchResult", search_results.ToList());
}
else
{
throw new NotImplementedException();
}
}
I have a dictionary I'm passing to a View. I want to be able to pass the values of that dictionary back to a Controller action from this same View. Is there anyway this can be accomplished without using a form? The situation is that I need to be able to pass these back to a controller action that is called when a user clicks an ActionLink from the View, and in my experience an ActionLink cannot be used to submit a values of a form, i.e. I've only been able to submit values of a form using the form's submit button. Unless there's a way to use an ActionLink to submit values in a form.Controller Action passes Dictionary to Controller in ViewData:
public ActionResult ModifyNewCrossListing(FormCollection form)
{
Dictionary<int, string> prefixlist = new Dictionary<int, String>();

When I first heard about ASP.NET MVC, I was thinking that would mean applications with three parts: model, view, and controller.
Then I read NerdDinner and learned the ways of repositories and view-models. Next, I read this tutorial and soon became sold on the virtues of a service layer. Finally, I read the Fluent Validation documentation, and I'll be darned if I didn't end up writing a bunch of validators.
Tonight, I took a step back and thought about what had become of my project. It seems to have become the victim of the design pattern equivalent of "feature creep". Somehow I'd gone from Model-View-Controller to Model-Repository-Service-Validator-View-ViewModel-Controller. You want loosely coupled and DRY? We got your loosely coupled and DRY right here! But I'm wondering if this could be a case of too much of a good thing.
Am I right to be concerned? Or is this actually not as crazy as it sounds? On one hand, it seems crazy to have so many layers. On the other hand, every layer has a clearly defined purpose that makes sense to me. Have your MVC applications turned into MRSVVVMC apps too? If not, what do they look like? Where's that right balance?
I have a table with a ID, CodeID,LibelleID field. I am using oracle connection. i want to display in a drop downlist (textfield) CodeID+LibelleID for exemple "100-SalaryBase" where CodeID=100 and LibelleID="SalaryBase" is it possible to obtain it if the user selects an element from the dropdownlist how to post both the codeID and ID to the controller
View 4 RepliesI have following situation - I am pasing user info object from Controller to View. It contains GUID UserID, which i dont want to be seen on page. So I removed every Html.LabelFor(model => model.UserID), Html.TextBoxFor(model => model.UserID) etc... from generated View source. And because of this when Html.BeginForm() returns that object back to Controller all values is there but UserID is lost??
If I leave Html.LabelFor(model => model.UserID), Html.TextBoxFor(model => model.UserID) etc.. in View everything is fine. But I dont want to show UserID? Where is the problem here?
<%= Html.LabelFor(model => model.C__User_Id) %>
I am getting started with Ap.net MVC. For that i chose to practice it by build an application. Im using MVC 2 and Linq To SQL, and i would like to passing another Query to the view. For example, i have this:
[Code]....
So i would like to pass data1 and data2 to the View. I can use return View(data1), but the View function accept just one data. So what technique i can use to pass the tow data to the view
I have the following to get the Json abject passed from the controller and populate the various textboxes in the view. However, nothing is happening even though controller is passing a valid Json object. What is wrong with this code?
<script language="javascript" type="text/javascript">
$(document).ready(function() {
var url = '<%=Url.Action("DropDownChange") %>';
$("#vendorID").change(function() {
var selectedID = $(this).val();
if (selectedID != "New Vendor Id") {
//$.post('Url.Action("DropDownChange","Refunds")', function(result) {
$.post(url, { dropdownValue: selectedID }, function(result) {
alert(selectedID);
$("#name").val(result.Name);
$("#city").val(result.City);
$("#contact").val(result.Contact);
$("#address2").val(result.Address2);
$("#address1").val(result.Address1);
$("#state").val(result.State);
$("#zip").val(result.Zip);
});
}
});
});
This is the code in my controller;
public JsonResult DropDownChange(string dropdownValue)
// This action method gets called via an ajax request
{
if (dropdownValue != null && Request.IsAjaxRequest() == true)
{
paymentApplicationRefund =
cPaymentRepository.PayableEntity(dropdownValue);
paymentApplicationRefund.Address1.Trim();
paymentApplicationRefund.Address2.Trim();
paymentApplicationRefund.Name.Trim();
paymentApplicationRefund.City.Trim();
paymentApplicationRefund.Contact.Trim();
paymentApplicationRefund.State.Trim();
paymentApplicationRefund.Zip.Trim();
return Json(paymentApplicationRefund,"application/json");
}
else
{
return null;
}
}
I've got problem with my app .
I've got such classes (this is some kind of tree structure):

in Index() action i've got this piece of code

I would like to pass List<SelectListItem> (not selected item but the whole "List" object) back to controller.
for example in my GET controller i would have this
ViewData["list"] = some select list from repository;
then on post I would like to get the list back from view..pretty much i'm trying to use ViewData["list"] as storage..this way I would use ajax to remove or add items to/from the list.
I'm having problems passing values from the controller to the view. I created a boolean variable to use as a flag and want the view to render some html based on whether its true or false.
Unfortunately ViewData doesn't look like it can pass boolean values. I should be able to pass any datatype to a view (string, int, bool, etc...)
ss a list of objects as a paramter in an actionlinkAt the moment when I try to do this the list is always empty by the time it reaches the controller!
<%= Url.Action("ActionName", new { list = Model.ListOfObjects}) %>
public ActionResult ActionName(List<Object> list)
{
//Do stuff
}
I need to pass a list of Entity Objects from Controller to View but not put it in the Model context. It is the users homepage, but I am putting a list of alerts on the users home page(somewhat like facebook). So I need the User Context as the Model I pass but need to pass the Alert model as well so I can show the list of alerts.. How would I do that? The code below is what I have so far..
UserController

UserRepository

I have a form that I don't want to post back so I need to get the form values into my controller via jquery's ajax method.Here is my test controller method:
[Code]....
When I debug the controller method and look at the lineItems parameter, it always contains 0 items. I've tried various formats for the javascipt lineItems parameter but still 0 items. I'm also open to some other way of getting these values in like the jquery form serialze method or something else.
This is probably basic stuff, but I can't find the clear answer anywhere..Lets say I'm doing an MVC (3) application with Entity Framework (EF4), and I have these three classes:
public class Foo
{
public int FooID

I am currently designing a new .NET application and would like to keep it UI independant.
Whilst I initally would like to use WPF, I would like to have the option of swapping the UI to ASP or WinForms if necessary.
In a layered design:
View - Interface Controller (ViewModel) - Model - Persistance
is it possible to design the Interface Controller so that it will work with different view technologies, or will I need to replace the interface controller at the same time as the View?
I am creating an instance of a business layer in the constructor of my Controller and then I am passing this to my view model like this;
[Code]....
The problem is when I make a post from the view with the viewmodel, I get an error that MyViewModel doesn't have a parameterless constructor defined, and I don't want it to have. Is there anyway I can pass the _businessLayer variable from the controller to the viewmodel when it's constructed "on the fly" in a method like this;
[Code]....
Maybe by using a custom model binder?
In my application, I need to get data from three tables and display them in 1 view. I have created a .dbml and created a ViewModel in my Models folder to deal with this. Here is my ViewModel:
[Code]....
My web application uses the Default ASP.NET Membership. So User [ u ] is of type aspnet_Users from the default Membership. This ViewModel allows all the CRUD opertation to be carried out. However on the Create and Update operations, I would LOVE some Model Validations, My question is:
1) Would the User [ u ] default validation kick into place in my ViewModel ? Cause I know by default ASP.NET Membership, has Model Validation.
2) For table SUserDetails (which I have created myself, not part of default) how do I add ViewModel validation to it for when someone does an Update or Create?
I am new to MVC, and trying something and got stuck somewhere in between.I have a user control there I have three textbox html type(ID, Lastname, firstname) and a submit buttom. I set the button like
<input type="button" value="Search"
onclick="location.href='<%= Url.Action("action", "controller") %>'" />
I have called this usercontrol on some view through
<%= Html.Partial("ucName") %>
Now on pressing that button(on user control) I need to pass the data from these textboxes to controller again to some specific action(Http Post action). By using this data I want to do some database interaction and storing the result in a dataset and pass this data set to same view again to show up in some Grid.I know the first part in conventional Asp.net can be done by raising the event through delegate but don't know how to do that in MVC.
Can i create a partial view and a controller that will feed data to the view, and if i render that partial in a Master page, the Data will show on whatever URL i am?
Or is there another way of showing content from database on every page(view)?
Basically, I have an HTML Form and would want to pass the data from the form to n asp.net mvc controller, then the controller would return an XML for client side manipulation.
Here is my initial code:

When I run and debug, I get a message that says "attr(..) is null or not an object. I am still trying to learn web development using ASP.NET MVC.
I have a view which takes two objects: booking and list of reasons for canceling that booking.I have two classes: clsBooking, clsBookingCancelationReason I can read both objects in my view - no problems there. After I read the objects, I display the booking details and I generate a list of cancelation reasons in the following way:
[Code]....
The code above generates a list of cancelation reasons.How do I pick up the selected ReasonId from the list?
I need to generate a link that will contain the bookingId and the selected reason for canceling the booking.I can get the bookingId out easily since it's stored in the Model...but how do I go about the selected ReasonId?
its said that 1 ViewModel has 1 View. 1 View is for me a UserControl. What if my UserControl has different areas filled with data from different entities, do I have then several Views and need to build several ViewModels? e.g: I display in a UserControl 3 entities: customer(listbox),order(datagrid),product(datagrid). Each of those "data areas" has add+remove buttons and textboxes to enter data.
Actually each of those "data areas" are put in its own GRID having so the posibility to set a individual datacontext.
1.) Should I now create 3 ViewModels CustomerVM,OrderVM and ProductVM?
2.) Are those 3 "data areas" seen as an own sort of separated View, although I have not put them in 3 UserControls.xaml files ???
3.) When this one UserControl is inside a TabControl`s tabpage where do I load the 3 entities related data? Inside the MainViewModel? I want to show/load that data only when the user clicks the tabheader.
In my page there is a Login form. It looks like
[Code]....
But at the same time in this page I need to render some info from another ViewModel. Is it possible to write in action something like
return View(Model1, Model2); ?And how could I get access to these ViewModels in this case?
I have a simple model where a Person has Gifts. I have a view which is a list of Gifts belonging to one Person.
My problem is with the Create action for a new Gift. I want it to default to the PersonID that we are already viewing the list of Gifts for. I tried simply passing the last PersonID (they are all the same)
Html.ActionLink("Create New", "Create", new { id = Model.Last().PersonID }) which works fine if there is already at least one Gift for that person but if this is the first Gift I don't have a value.
My Gift List controller knows the PersonID I want to pass but the view doesn't.
How do I pass this PersonID from my Gift List controller to my Gift Create controller via the Gift List view? Or is there a better way to do this?
