ASP.NET TempData persists between requests

Question

I am using temp data as follow in my controllers - very simple, when there is a problem:

TempData(\"StatusMessage\") = \"You have no items set to Auto-Ship.\         


        

Answer 1

would this be acceptable (removing the error once it has been shown):

<%  If TempData.ContainsKey("ErrorMessage") Then %>

<%=TempData("ErrorMessage") %>
<% 
    TempData.Remove("ErrorMessage")
End If
%>
