Conditionally Show Model Objects In View Depending On Dropdownlist Value

Mar 24, 2011

Using ASP.NET MVC 2, I have a model for a view. The view has a dropdownlist of roles that is populated by the model and there is a list below that of checkboxes with a number of privileges. I want to show only specific privileges depending on the dropdownlist selected roleID and have it update the privileges everytime the dropdownlist changes. I know how to do this in web forms ASP.net with absolutely no problem but I cannot seem to figure out where to start in ASP.NET MVC. Can someone please advise me what I need to do or towards a tutorial that will show me what to do? I am a novice in MVC.

MVC :: How To Update A Collection Of Objects In A View Model

Sep 14, 2010

I have been trying to design a form, which uses a view model that contains an object array. I want to set up this form so that when the submit button is clicked, all the members of the array are updated. Here is my code:

The class definition of the array element:

[Code]....

The problem is that when I clicked the submit button, none of the luSubject objects in the array Subjects got updated. But if I set up some initial values for the members of the luSubject objects, for instance, set the Name field to be "Maths" in the constructor of luSubject class, then it got displayed on the text box when the form page was loaded. This suggests that this form could display the data in the array, but cannot update it.

MVC :: Store Model In Separate Class Library- Pass Model Objects?

May 19, 2010

I'm building an MVC 2 RTM app, and I want to be able to share my model across applications. I'd *like* to be able to implement it like:ASP.NET MVC2 app (holds Views and Controllers)Class library to hold Model(s)WCF app to handle the data transactions with the models via different data stores across apps I had the MVC app working fine, but I wanted to abstract the data stuff and be able to work with the model across apps through the WCF site, so I created a class library project and moved all of the Models classes into that and set-up a WCF app, then added project references to the MVC and WCF apps that point at the class library. The idea was I can create services that take and return objects from the model via method calls across apps. It appears that everything's wired up correctly in the MVC project, so I'm passing the objects stored in the Models class library between controllers and views and everythig is compiling just fine, but for some reason the data is not being passed back from the views to the controller on POST -- all of the properties in the classes are null or empty.

When I debug the app, I can see that the values are stored in the model data dictionary but not the model object itself. What am I doing wrong? Am I on the wrong path, or missing something obvious (to some)?

MVC :: Dropdownlist Validation Not Working For Complex View Model

Feb 3, 2011

I have a question regarding validation of drop-down list values. I have a view that is bound to a view model type called ReservationData.

This object contains a property CustomerVehicles of type List<VehicleData>. VehicleDatahas two int properties VehicleMakeId and VehicleModelId.

On my view I am trying to loop over the number of items in the CustomerVehicles collection and displaying two dropdowns for each, a vehicle make dropdown and a vehicle model dropdown usingDropDownListFor.

When I try to submit and validate I do not see any validation errors displayed on the screen.

Just in case you are wondering I have added a ValidationMessageFor for each dropdown as well. I am not sure if this is an issue with the structure of my view model and its complexity and how the controls need to be named or how the ids need to be set.

Here is the code for the looping over the collection:

Model View Presenter - How To Show Selected Item In A Drop Down List

Jul 23, 2010

I'm using Model-View-Presenter framework. When Loading a page, I'm having trouble setting the selected item that came from the Database.

In view, I know I need:

protected void ddlStatus_SelectedIndexChanged(object sender, EventArgs e)
{
presenter.DdlStatusSelectedIndexChanged();
// what should this pass?
}
Then in Presenter:
public void DdlStatusSelectedIndexChanged()
{
view.DdlStatus = ???
// Should I pass the SelectedIndex?
}

I also think that part of my problem is that DdlStatus I have as a List.

Interface:

List<StatusDTO> DdlStatus { set; get; }

The best I found is here (but needs formatted!) ---> [URL]

Data Controls :: How To Show GridView Image Conditionally

Nov 9, 2013

For this I am using ASP.NET 4.5, C#, and Entity Framework to SQL.

I have some sections of my site where users can make multiple entries and can optionally upload attachments. There is a page where the user can see a gridview that acts as an overview of the entires. I have been asked to display a column with a paperclip icon if an attachment exists.

The way the database is structured, the table that holds the entries has columns like this:

id, schoolName, dateStarted, dateEnded, attachmentId

The attachments are in another table. For this table the attachmentId will hold an Int32 or be NULL (no attachment). My current query looks like basically like this: 

var query = context.applications.Where(c => c.id == applicationPrimaryKey);
var results = result.educationUniversities.ToList();
gdvEducationUniversity.DataSource = results;
gdvEducationUniversity.DataBind();
 
Gridview looks like this:
 
<asp:GridView
ID="gdvWorkMentor"
runat="server"
AutoGenerateColumns="False"
DataKeyNames="id"
<Columns>

[Code]....

I somehow need to create a condition where an image of a paperclip is shown if the attachmentId value is not Null. Optionally I imagine the query could be re-written to return a true/false value based on if the attachmentId value is null though I'm not certain how to do this.

I've tried to use conditional logic on the .aspx page when setting the Text property, but everything I've tried results in an error. I've also tried using code-behind to set the Tetxt property in the Page_Load event. This doesn't generate an error, but it doesn't set the property either.

Should Data Annotations Be On The Model Or The View Model

Dec 15, 2010

I've been used to decorating data model classes with data annotation attributes, but the purist in me baulks slightly at including purely presentational attributes such as display format here. I am, however, quite happy to keep validation centric attributes here. One good reason I have to continue keeping all annotations etc. in the data model is that my view model aggregates data model classes, e.g.

my ViewModelBase.DetailItem<TEntity> property in the view model is just a reference to an entity class in my data model. If I wanted to move presentational annotations to the view model, I would have to quite radically revise my design to one where I duplicate data model properties in my view model and use an object mapping tool to populate view model objects based on data model objects.

MVC :: View Model To Convert To Domain Model?

May 4, 2010

Say I got a domain model as follows: (and my repository expect an instance of this object)

[Code]....

And a view model (which my views are based on)

[Code]....

At the moment I got it like this and have my controller action manually create a new Person object from the PersonModel object before passing it on to the repository, which does not feel right.

So I tried to have PersonModel inherit from Person and pass that to the repository (also tried casting the PersonModel to a Person object first), but that don't work out.

What's the right way to have PersonModel automatically cast to Person? I want to keep this logic as my current structure allow me to keep things really loosely coupled, with the repository layer not having a clue how it's being used.

Web Forms :: Hide / Show CheckBoxList Depending On Users Profile

Nov 16, 2010

New users can register on my site by completing a basic form that has the create user wizard control with some additional information i am collecting using a CheckBox List. They can then log in to the site and and view "MypProfilePage.aspx" where I display the information with the CheckBoxList boxes already ticked based their selections which they can update. My problem is I have two levels of User and each one has a different registration form.

Registration Form A
Has 20 Items in the CheckBox List

Registration Form B
Has 10 items in the CheckBox List

On the Profile Page, I just want to show the CheckBox which is relevant to the Registration form A or B and with selections by the registered user. So therefore the User who registered on B will not be able to see the selections checkbox list for A.
