Question

I don’t really know how to deal with the next issue :

So, I’ve a webbased application developped with ASP.NET MVC3, which is used to remember when an event is relayed to some people.

I’ve 3 tables

Contact
 id_contact
 name
 firstname
 ...

event
 id_event
 ...

transmission
 FK_id_event
 FK_id_firstname
 mailed (boolean)
 phoned (boolean)

For each event, I need to list all the contacts that are related to this event. And for each contact, I need to display 2 checkboxes that have to be checked if the contact has been called or mailed.

    '
    ' GET: /Event/Details/5

    Function Details(id As Integer) As ViewResult
        Dim event As event = db.event.Single(Function(o) o.idOpportunite = id)

        Dim contacts = (From a In db.contact, b In db.transmission
                       Where a.id_Contact = b.FK_id_contact And b.FK_id_event = id
                       Select a)
        Dim transmission = (From a In contacts, b In db.transmission
                        Where a.id_Contact = b.FK_trans_cont
                        Select b)

        Dim model = New EventDetails With {
            .event= event,
            .Contacts = contacts,
            .TransOpp = transopp
            }

        Return View(model)
    End Function

I don’t know if the “transmission” part of the code is good or not.

Here in the view, this is were I display the contacts

        @For Each contact In Model.contacts
            @<tr>
                <td>
                    @Html.ActionLink(contact.name + " " + contact.firstname , "Details", New With {.id = contact.idContact})
                </td>
                <td>
                    @Html.Raw(contact.phone)
                </td>
                <td>
                    @*Html.DisplayFor(Function(modelItem) currentItem.mail)*@
                    <a href=mailto:@contact.mail>@Html.Raw(contact.mail)</a>
                </td>
                <td>
                   ***My checkboxes should be here***
                </td>
            </tr>
        Next

So, my question is, what should I do to display those checkboxes?

(sorry if I’m not understandable, I’m not a native english speaker. Don’t hesitate to edit my english mistakes (or the title which is not a great one)).

With the help of Yasser, I’ve done this :

                    @code
                    Dim mail As Boolean = (From a In Model.Event
                    Where a.FK_id_contact = contact.idContact And a.FK_id_event = Model.Opportunite.idOpportunite
                    Select a.mailed)

                    End Code

However, I get an error :
Value of type ‘System.Collections.Generic.IEnumerable(Of Boolean)’ cannot be converted to ‘Boolean’.

Answer 1

Here is something that should help

 @{ 
 bool isMailed =  // set values;
 bool isPhoned = // set values
  }
@Html.CheckBox("mailed ", isMailed );
@Html.CheckBox("phoned", isPhoned );
