DNN Consultants with years of Experience

Back in 2004, when Efficion was just starting up and open source Content Management Systems were a fairly new concept, Efficion performed an exhaustive evaluation of the most popular CMS's in order to choose the best to build our business around. We chose DotNetNuke.

Built on top of the wonderful ASP.NET framework, it was technically superior, had a great community, a growing ecosystem, excellent leadership, had a great, extensible architecture, and was a very solid product. To this day, I feel strongly we made the right choice.

Since then, we've built the majority of our websites, intranets, and web applications on top of DNN. We offer a full range of services. Visit our services page to learn more.

DotNetnuke: Is user an admin / administrator

DotNetNuke makes it easy to determine if the currently logged in user is an administrator (aka admin) or any other role for that matter. All you need to do is call the following: PortalSecurity.IsInRole("Administrators") or PortalSecurity.IsInRole("MyRoleName"). This function should return the boolean value very quickly as everything it needs is already in memory. You can call this from either the code behind or the ascx file (e.g. Visible='<%#PortalSecurity.IsInRole("Administrators")%>').

This can be very useful for determining whether or not to show a control or content meant only for the right groups eyes.

Is your DotNetNuke site running slow

A common performance issue in some versions of DotNetNuke

Is your DotNetNuke site running ridiculously slowly and consuming massive amounts of your processor? It might be stuck in a bit of a catch 22... The scheduler is trying to clear the ScheduleHistory table, but it can't because the ScheduleHistory table is too full.

Custom Toolbars in the FCKEditor Provider for DNN

When it comes to the toolbars for Rich Text Editors for clients to use to update there own sites, it is my firm belief that less is more. By default, the toolbars seem to be cluttered with endless options that rarely get used and in the end just make it harder to find the options users do need.

The FCKEditor Provider for DotNetNuke is great overall and exposes almost everything you need to set it up just they way you want it, including setting up different custom toolbars for different types of users (determined by role). But I haven't found much clear and concise documentation for adding your own custom toolbars. Here is how I do it...

DotNetNuke: Getting User Profile Data through SQL

*** Updated: Added method for DNN versions 3.3 and 4.3 and greater ***
DNN 3.0 - 3.2
In DNN 3.0-3.2 and 4.0-4.1, the membership / profile stuff made heavy use of Microsoft's Membership provider module which stores most of the information in a hash table. While this is fine for getting a single user, it's a complete nightmare if you want to show a grid or list of many users or to do something with the data in SQL.

There's a good write up on how to get at this info through SQL at DNN Stuff.

DNN 3.3+ and 4.3+
The core team did a complete and much needed overhaul of the User Profile system for DNN 3.3 and 4.3. The grid on the User Accounts page is now a lot more flexible but it still won't help you if you want non-admin users to view user data or if you want to utilize profile data in SQL... Click on the Read More link to learn how to get at DNN 3.3+ profile data in SQL. This data could then be displayed using the Advanced Data Grid
