jQuery Tips for DotNetNuke Developers

By -

  1. Make sure you call jQuery.noConflict();. This is necessary to not cause other client scripts and libraries to run errors. This is due to the fact that other client scripts might be using the $ designator for a JavaScript class. [jQuery.noConflict(); documentation]

    2.
  2. If manually adding jQuery, try to load the jQuery library in the header before all others. Not doing this can lead to the jQuerylibrary not being loaded before another client script or library tries to use it. This is especially true of jQuery plugins.

    3.
  3. Always call the jQuery core methods using the jQuery() format. This is related to the previous issue.

    4.
  4. Check the jQuery plugin source code. Not all jQuery plugins use the long form of calling jQuery. This can result in errors if you have called jQuery.noConflict();.

    5.
  5. In DNN 5+, register jQuery. DNN 5+ allows module developers to register jQuery to be loaded only when modules need it. Just callDotNetNuke.Framework.jQuery.RequestRegistration(). This prevents jQuery from being loaded when it’s not used. If your skin is using widgets, this is not necessary, but should be done for commercial modules regardless.

    6.
  6. Use the jQuery hosted option. Look in the Host Settings (DNN 5). This is not necessary, but can reduce page load times, since the site visitor may already have the library loaded in case. However, if the hosted source is having problems hosting the library, your page load times could increase dramatically, as well as not load the library at all. Either way, your client side-code will break.

  7. Only use jQuery Debug Version for debugging. Look in Host Settings (DNN 5). By default, DNN loads the jquery.min.js file. However, when you are debugging jQuery, this makes it nearly impossible to debug. Check this setting to tell DNN to load the uncompressed version of the jQuery library. Only do this on development machines, if possible.

  8. Wrap onload scripts in a ready() function. Wrapping your scripts in the ready() function prevents conflicts with other scripts on the page, including Microsoft scripts, and the DNN Client API.

Hey Kishan,

can you assist with a DNN blog prob I have?
Is there a way to add the image element to the dnn blog module rss feed so it can be pulled by mailchimp for my weekly rss-to-email newsletter? I use Live Writer to publish to my dnn blog.

SQL Server 2016 TDE ( Transparent Data Encryption)

By -
Image
Transparent Data Encryption is designed to protect data by encrypting the physical files of the database, rather than the data itself These physical files include the database file (.mdf), the transaction log file (.ldf) and the backup files (.bak). Its main purpose is to prevent unauthorized access to the data by restoring the files to another server.  With Transparent Data Encryption in place, this requires the original encryption certificate and master key. The protection of the database files is accomplished through an encryption key hierarchy that exists externally from the database in which TDE has been enabled. The service master key exists at the instance level. The database master key and certificate at the Master database are used to protect the database encryption key that is located at the user database The dependency upon the encryption key hierarchy in the Master database, as well as the instance, prevents the database files from being restored to an instan

Setting Up Active Directory Integration with DotNetNuke Seems like enough people ask, and the information is hidden enough around the DNN AD forum that this information could be posted in one place.  These are the steps I take to get my DNN AD integration to work every time.  I have never had it fail.  I hope you find it helpful.  Now if you are setting up your AD in Mixed-Mode most likley this little write up isn't for you. The setup process is a three step process.  The first step is done from within DNN.  The second step takes place in DNN’s web.config file.  The final step takes place in IIS. Within the DNN Website Login as Admin or Host to your DNN website. After login go to                                                                i.     the Admin tab                               ii.   and then select Authentication You will now see the Active Directory Setup Screen. Fill out the screen as follows.
