New in 2sxc 7: #10 Create Your Own Custom DataSource for the Visual Query

The Visual Query / Pipeline Designer helps you build a chain of data-preparation actions.

Now what if your data comes from another source? For many things you can use the DnnSqlDataSource - but it won't cover everything. We'll add more DataSources in the future, but if you need anything custom - just create your own.

There are many cases where you would like to create a custom DataSource - for example:

  1.  Maybe you would like to have a FileDataSource which gives you a list of files from a specific folder…
  2. Maybe you want to get an RSS-Feed - just create an RssDataSource
  3.  Or you want to get JSON data - JsonDataSource
  4.  Or you want to help all the people who worked with Ventrian Articles and would like to create a VentrianDataSource where the designer doesn't need to know SQL - similar to our DNN FormAndList DataSource In all these cases, just create your own DataSource.

To help you get started, I've prepared a bunch of stuff for you

#1 A Demo Visual Studio Solution with a Custom DataSource

The entire solution is on GitHub here: Just download or fork or whatever. It contains:

  1.  A DateTimeDataSource demonstrating all kinds of features and best practices  
  2. A Unit-Testing project to test the code We strongly recommend that you use unit testing with all DataSources (we do too) because otherwise testing just takes too long in a live web.
  3. Hint: in Visual Studio - press "Ctrl+R, A" to quickly run all the unit tests automatically

#2 A App containing Demos and Configuration

This can be found here:

It contains:

  1. Some intro-help text
  2. Some demo queries using the DateTimeDataSource
  3. A content-type called "|Config MyCompany.DataSources.DateTimeDataSource" which the visual Query Designer opens when you want to configure your custom DataSources.

Have fun!
