Smoothing out a few wrinkles - Code
These are the files that have been amended during this process. Not all changes were documented in the YouTube video. I also took the opportunity, to
- Deal with the numeric textbox on the products page.
- Tidy up the menu by removing 'Counter' and renaming 'Home' to Purchase Orders' and editing the menu title to add spaces between words.
- Delete redundant files, viz.
- Counter.razor
- SurveyPrompt.razor
- FetchData.razor
There were no changes to any SQL.
