My View looks like this:
<%@ Control Language="C#"
Inherits="System.Web.Mvc.ViewUserControl<TMS.MVC.BusinessSystemsSupport.Models.SearchDataTypeModel>" %>
<table class="classQueryResultsTable">
<!-- the header -->
<tr class="headerRow">
<td>
<%= Html.ActionLink("Effective Startdate",
"SortDetails",
"DataQryUpdate",
new
{
model = Model,
sortBy = "EffectiveStartDate",
},
new { @class = "classLinkLogDetails" })%>
</td>
</tr>
</table>
My controller action:
public ActionResult SortDetails(SearchDataTypeModel model, String sortBy)
{
The model parameter is null. The sortBy parameter is populated. I can pass in a String property from the model to the action with no problem. I want to pass in the entire model though.
Any ideas what I'm doing wrong?

You can't pass complex objects:
model = Model
makes no sense and cannot be sent using GET. You might need to use a form with an editor template and/or hidden fields to send all the model properties. Remember only scalar values can be sent in the query string (key1=value1&key2=value2...). Another alternative that comes to mind is to send only the ID:and in your controller action fetch the model given this id from your data store:
Of course this is only true if the user is not supposed to edit the model properties in a form. Depends on your scenario.
And for the sake of completeness let me expose another option: use the Html.Serialize helper from MVC Futures to serialize the entire model into a hidden field which could be passed back to the controller action and deserialized there.
