    <p>As per : <a href="https://stackoverflow.com/questions/8759244/mvc3-model-binding-pagedlist-to-viewmodel-with-custom-editortemplate-and-partial">MVC3 Model binding pagedlist to ViewModel with custom EditorTemplate and Partial View</a></p> <p>See above question for code snippets</p> <p>The problem i am having now surrounds binding the custom IPagedList collection. The model binder attempts to bind the values to the property on the ViewModel but is unable to create an instance of the interface (no suprises there).</p> <p>So how can i bind values back to my viewModel by instantiating a concrete PagedList class when the values are bound? As i understand it the IEnumerable binder does this for a List or similar derivitive, so how can i do this for my custom class/interface?</p> <p>Do i need a custom model binder for this? If so any information or code tips on this is great!</p> <p>Any help greatly appreciated thanks.</p> <p>Update:</p> <p>Changing the ViewModel to include an overriden default constructor which initialises the Interface like so:</p> <pre><code>public class RequestCreateViewModel : ViewModelBase { public IPagedList&lt;CreateRequestModel&gt; PagedList { get; set; } public RequestCreateVieWModel() { PagedList = new PagedList&lt;RequestCreateModel&gt;(new List&lt;RequestCreateModel&gt;(), new PagingOptions()); } </code></pre> <p>.. appears to allow the default model binder to work as per my comment. But it doesnt seem like a great solution, mainly because im needing to infer new object parameters for the PagedList object each time a ViewModel is created. Am i needlessly worrying?</p>

    1. COI would look into the custom model binders. Intimidating at first, but not too bad. You can do a lot with this feature. Keep in mind there are two distinct ways to do this. Inheriting from DefaultModelBinder and creating your own binder that simply implements IModelBinder.

    3. COHaving added a Constructor to the ViewModel object with a initialisation for the Interface the default binder does its work and binds with the correct naming of course. Inspiration came from: http://stackoverflow.com/questions/5749775/implementing-asp-net-mvc-3-interface-model-binding-with-viewmodel But it does avoid having to create a custom model binder for this... So my question still stands whether this is a good idea or not?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
