Ever want to sort your result set but make sure the records with a null sorting column appear last?
See the example below
var results = (from x in EntityObjectContext.MyTable
mydata = grp,
myid = grp.id,
mysortingentity = grp.mysortingentity
).OrderBy(x => sortingcolumn == null).ThenBy(x => x.mysortingentity.Name).ThenBy(x => x.myid);
Watch this space, this can easily be transformed into a Extension Method. Check out this link http://tahirhassan.blogspot.com/2010/06/linq-to-sql-order-by-nulls-last.html, this Extension method works for LinqToSQL.
I came into an issue where I have Elmah configured on a ASP.NET MVC 3 website. I notice that the errors were not getting logged or emailed as per my configuration settings in web.config.
I found that MVC3 Error Handling was handling all the errors before Elmah could handle the error and report it correctly.
This link was very helpful:
Also when using Elmah on a production environment, its a good idea to lock down the permissions for the elmah.axd handler so only users in a particular role have access to this file. (Assuming that your website is using forms authentication and role provider)
<allow roles="Administrators" />
<deny users="*" />
And also make sure that this setting is set to false so its not available to remote users.
<security allowRemoteAccess="0" />
