Question

This may be an easy question, but if it is one i haven’t found a solution. I have a view model that is updated when a button is pressed, and on the update an IList within it will be given some results (this i know works). However i am trying to bind this Ilist to a gridview within the view page. Every time i try to assign a datasource or datasourceid, firstly my resharper is hostile towards it saying it should be removed, but when i try to run it crashes on load. Does anyone have any insight on how to proceed?

You shouldn’t be using server controls like GridView in an ASP.NET MVC application. Those controls rely on ViewState and PostBack models which are a no-no in MVC. There’s no notion of data binding either. Your controller is passing a view model to the view (a list in this case) and the view has to render it. There is a nice HTML helper in MVCContrib.Grid which you could use to display data in a table. It also supports paging and sorting. If you don’t want to use third party helper methods you could loop through the model in your view and manually generate the <tr> and <td> but this could be a tedious task. So yes, back to the basics, back to the real world wide web. No longer leaky abstractions such as WebForms.

So to conclude: in an ASP.NET MVC view <asp:XXX runat="server" ... /> are forbidden. Simply remove them from the views. I would also recommend you going through the tutorials here.
