Updating DotNetNuke (DNN)




1)      Download the latest version. it will be a zip file.
2)      Extract it to a folder.
3)      Now you need to make backups of files that will be overwritten by the DNN upgrade.  If there are a important changes you will have to merge them.
a.      Files that were customized.
b.      Ex: Login ascx page in the DesktopModules/Authentication/DNN folder which I customized it so that the page would fit on mobile devices.
4)      The upgrade may influence the look of the page with the skin.  You may have to modify the skin, Eg:Powerful.  Find that in the Portals/default/Powerful/skin.ascx folder. 
5)      Make a backup of the database, and a copy of the existing website folder on the website, in case it screws up.  We have experienced complete corruption of the install before so this step is important.
a.      If you need to restore, take the DNN db offline/disconnect all users before restoring otherwise it will not work.  Then bring it back online.
6)      When ready copy over the contents from the upgrade folder to the existing website folder.
7)      Make sure Users on the server in the website folder have write access.   I had encountered issues in the Install/Cleanup folder. 
a.      When the install process did not finish properly it would not rollback changes, and would remove files in that directory.  You may need to copy the missing files back in there if the install fails and you have to restart.
8)      Run the site, and go through the installation. 
a.      When upgrading to 7.04 it hung at 41% for 10 minutes or so before completing.
9)      Test the site to make sure it still works.

Asp.net Publishing Broke Site - "App_WebReferences is not allowed because the application is precompiled"

When publishing site to live, trying to go to site gives a Server Error – Runtime Error.  Looking in the Application logs on the server  gave " The directory App_WebReferences/ is not allowed because the application is precompiled."   This was causing a bit of stress to a programmer in a our company since he tried to publish a change during business ours.   Solution http://stackoverflow.com/questions/9892646/how-publish-my-web-site When publishing the options that work are to have “Delete all existing files prior to publish”, and “Precompile during publishing” checked.  And “Exclude files from the App_Data” unchecked.

Telerik - Custom Group Footers In RadGrid

As anyone that has dealt with this knows Telerik only supports a single Group or Header Template.  So what happens when you want to change them?  You really only have two options from what I have seen.  The first option is to have something in the data that is brought back that you can use in the designer code in the form of a conditional.  Too bad I do not see a way to check the data based on level like some sort of ParentID like some people have done.  If the ParentID is null  It would look something like below where you check it in the designer: < asp : Label runat = "server" ID = "Label2" Text = '<%# "Number of items in group: "+ (((GridGroupHeaderItem)Container).AggregatesValues["AvailableUnits"]) %>' Visible = '<%# ((((GridGroupHeaderItem)Container).AggregatesValues["AvailableUnits"]) != null)%>' > Or you can use the code behind to really get at the groupIDs like this per

Bootstrap Modal Popup is Grayed Out

The popup shows up, but after it pops up the whole page becomes unusable.  So not only was it not displaying right, the whole page is frozen.  I found a StackOverflow post, below describing how the popup may have that behavior when it is nested inside elements that have positioning elements, which fits with previous experiences I have had.  One of the answers described how appending the modal popup to the body of the page  "$('#mytModal').appendTo('body');" would be a way of getting it out of any positioning elements.  Previously on a different page I had moved it out of some divs and it worked right.  However in this particular site the modal is in a ASP.Net site as a user control where the "offending" positioning element is in the master page and it contains the user control.  I stuck the script in the user control, but the behavior was the same.  When I used Firebug I saw that I was getting a "$ is not defined" message. With Jquery we ne
