i have used the following code in my view and made the model it is giving the error in (IEnumerable<ITClassifieds.Models.Resume>)
<%--
foreach (ITClassifieds.Models.Resume c in (IEnumerable<ITClassifieds.Models.Resume>)ViewData["getresume"])
{ %>
<input type="radio" name="resumeID" value="<%=c.ResumeID %>" checked="checked"/>Yes
<input type="radio" name="resumeID" value="0"/>No
<%} %>
Go back to where you are setting getresume in your controller.. confirm that it is setting to what you are expecting.
Post the full error you are receiving.
