    text
    copied!<p>I've searched all over the web but not finding the solution for the following problem:</p> <p>Say I have three ViewModel classes</p> <pre><code>public class ViewModelNewPerson { public string PersonName; public string Address; public string EyeColor; //etc } public class ViewModelSelectPerson { public int SelectedPersonId; } public class ViewModelComposite { public ViewModelSelectPerson selectViewModel; public ViewModelNewPerson newPersonViewModel; } </code></pre> <p>and I want to do the following things:</p> <p>In the <code>Controller</code> I want to create a <code>GET</code> <code>Action</code> which uses the class <code>ViewModelComposite</code> as its Get model, and in the view I want the user choose from the following two available actions: to choose a existed person, and to add a new person as the selected value.</p> <p>So I need to create two forms in the <code>View</code>, and there would be two <code>POST</code> <code>Action</code>s added to the <code>Controller</code> using the Post model of class <code>ViewModelNewPerson</code> and <code>ViewModelSelectPerson</code>.</p> <p>My question is, how can I do the manual model binding using a Custom Model Binder that can convert the Composite class of <code>ViewModelComposite</code> to <code>ViewModelNewPerson</code> in the <code>Action</code> of create a new person, and to <code>ViewModelSelectPerson</code> in the <code>Action</code> of select an existing person?</p> <p>EDIT:</p> <p>Now I have an idea of decomposing the class <code>ViewModelComposite</code> and declare every property in the two classes into the composite class, and the default model binder will do the trick, I think. But that'll drop the composite pattern, and is not something I wanted.</p>
