Create MVC Custom Model Binder for model tuples

Question

Need assistance in creating a MVC Custom Model Binder to post multiple model tuple to controller. Never worked with custom model binder. Have looked at other answers to this issue but, don't seem to come close in dealing with a tuple of models or provide desired solution. Any ideas are appreciated. - Thanks

View

@model Tuple<Contact, Communications, Addresses>
@using (Html.BeginForm()) {
  <div id="contact">
    <div class="editor-label">
         @Html.LabelFor(m => m.Item1.FirstName)
    </div>
    <div class="editor-field">
        @Html.TextBoxFor(m => m.Item1.FirstName)
    </div>
    <div class="editor-label">
        @Html.LabelFor(m => m.Item1.LastName)
    </div>
    <div class="editor-field">
        @Html.TextBoxFor(m => m.Item1.LastName)
    </div>
    <div>
        <input type="submit" value="Create" />
    </div>
  </div>
  <div id="communication">
    <div class="editor-label">
        @Html.LabelFor(m => m.Item2.TelephoneValue)
    </div>
    <div class="editor-field">
        @Html.TextBoxFor(m => m.Item2.TelephoneValue)
    </div>
  </div> 
  <div id="address">
    <div class="editor-label">
        @Html.LabelFor(m => m.Item3.Address1)
    </div>
    <div class="editor-field">
        @Html.TextBoxFor(m => m.Item3.Address1
    </div>
    <div class="editor-label">
        @Html.LabelFor(m => m.Item3.City)
    </div>
    <div class="editor-field"> 
        @Html.TextBoxFor(m => m.Item3.City)
    </div>
    <div class="editor-label">
        @Html.LabelFor(m => m.Item3.StateProvince)
    </div>
    <div class="editor-field">
        @Html.TextBoxFor(m => m.Item3.StateProvince)
    </div>
    <div class="editor-label">
        @Html.LabelFor(m => m.Item3.PostalCode) 
    </div>
    <div class="editor-field"> 
        @Html.TextBoxFor(m => m.Item3.PostalCode, new { id = "zip", style = "width:90px;" })
    </div>
  </div> 
}

Contoller

[HttpPost]
public ActionResult CreateContact(Tuple<Contact, Communications, Addresses> tuple) {
      //…. Do tuple processing to transfer values to add values to App Service here.
}

Answer 1

Why dont you try keeping the "Contact, Communications, Addresses" models inside a new model and bind it to the view.

It will make handling very simple.
