Tutorial: Barcodes, QR codes, and RFID tags
Learn to create the Order Entry Form that works offline and online. The form will handle barcodes, QR codes, and RFID tags. The tutorial explains how to calculate the default values, extended price, and order total.


We start with the live demo of the app that will be created in this tutorial. Next we proceed to create the Order Entry Form shown in the demo and make it work in online and offline modes. The next iteration of the app is using UI Automation to implement the barcode processing for Product inventory, QR-code processing for Customer Loyalty Cards, RFID tags to handle Employee Access Cards. We bind it all together for Hands-Free Order Entry. The final part of the tutorial concentrates on creating the Kiosk-style presentation for the Order Entry Form.

Inline Editing in Multi-Level Master-Detail Pages

Hey there! We are working on completing the video tutorial covering the new multi-level master-detail support in the release 8.7.0.0.  The release has been accumulating numerous features over the past three months. The wait is almost over.

The screenshot shows a master detail page with three connected data views (Customers, Orders, Order Details).

User is entering the freight amount for an order in the screenshot. Inline Editing makes it possible. The feature requires zero programming. All of your grid views support editing as shown at https://www.youtube.com/watch?v=L4tbC5ZeUwA&index=1&list=PLy2g3SjvDe2b2cl9i0msBaMVLntQucZtb.

Notice the horizontal scrollbars showing the depth of grids. The styling of pager has been changed as well.
Three-Level master detail page in app created with Code On Time.

All types of input are working in inline editing mode, just like they do in the forms. Here is  a lookup control with auto-complete feature. Enormous amount of work has been put in comprehensive keyboard navigation support in forms.

Touch UI supports data input in Inline Editing mode.

Apps created with Code On Time support inline editing on mobile devices. The screenshot shows “mobile” inline editing mode.

Mobile inline editing is unique and exclusive to apps created with Code On Time.

Inline Editing is fully supported in List and Cards modes as well.

Edit data inline in grids, lists, and cards or your app.

Don’t forget – native apps, custom search, and a host of other features are coming your away. Subscribe to our YouTube channel and get notified when the new tutorials are out!
