New LightSwitch “How Do I” Videos Released Today

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

• #9 - How Do I: Create a Screen that can Both Edit and Add Records in a LightSwitch Application?
• #10 - How Do I: Create and Control Lookup Lists in a LightSwitch Application?

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.

• #1 - How Do I: Define My Data in a LightSwitch Application?
• #2 - How Do I: Create a Search Screen in a LightSwitch Application?
• #3 - How Do I: Create an Edit Details Screen in a LightSwitch Application?
• #4 - How Do I: Format Data on a Screen in a LightSwitch Application?
• #5 - How Do I: Sort and Filter Data on a Screen in a LightSwitch Application?
• #6 - How Do I: Create a Master-Details (One-to-Many) Screen in a LightSwitch Application?
• #7 - How Do I: Pass a Parameter into a Screen from the Command Bar in a LightSwitch Application?
• #8 - How Do I: Write business rules for validation and calculated fields in a LightSwitch Application?

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

Enjoy!

  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

  @Matt -- check out this forum thread for a work-around: social.msdn.microsoft.com/.../5ae66a6d-5723-4ab7-8e53-64408d326d5d @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: connect.microsoft.com/visualstudio Thanks, -B
