New LightSwitch “How Do I” Videos Released Today

  • Comments 7

We just updated the Learn section of the LightSwitch Developer Center with a couple more videos, check them out:

The team also has a couple blog posts on these topics if you like articles better than videos:

How to: designing one LightSwitch screen to create or edit an entity
How Do I: Filter Items in a ComboBox or Modal Window Picker in LightSwitch

We’ve also added a couple new features to the video pages which allow you to rate the video (5 stars being the best) as well as a related videos section so you can see the most watched videos in the series. I still recommend you watch them in order because the videos build upon each other as we create a sample application for order entry.

If you missed them, here’s the first 8 videos.

Next ones I’m working on will be on Security and Deployment so stay tuned.

  • Hi Beth!

    Are you planning to make videos about connecting to existing databases and working with them?



  • Hi Tamas,

    Yes, I'll add that to the list. Thanks!

  • Hi Beth,

    Is there any way to add a splash screen at this stage to a lightswitch project at this stage and is it possible to modify the look of the search/data screens? For example, perhaps adding an application logo to the screens etc. Any advice you can provide would be appreciated

  • sql fetch is very slow .. you must try to table with 1000 record and over 5 join and see search screen .. what do you things about this problem

  • @Matt -- check out this forum thread for a work-around:

    @atilla -- You can limit the amount of data rows that come down by specifying that in the Screen designer and specifying the # of records to fetch on the query. We are also still working on peformance issues in Beta 1. Please report your repro steps here so we can investigate:
