Restrict Text Input Values

To ensure a text input control only accepts numbers, modify the default Format attribute to “number“. This ensures characters other than numbers are excluded. To further enhance this, adjust the MaxLength attribute to mirror the maximum character restriction of the field.

    // Setting format for an input named "InitiationYear"
    // Setting MaxLength for an input titled "ProjectTitle"
    DataSourceInfo(ProjectsDB, DataSourceInfo.MaxLength, "ProjectTitle")

Ensure Form Data Accuracy

Validation is paramount. Before a form’s submission, verify the following:
  • Essential fields are populated
  • Entries like phone numbers, emails, postal codes, etc., are formatted correctly
  • Numerical entries are within permissible range
  • Confirmation fields (like passwords) match
Users benefit from real-time feedback. There are two methods:
  1. Post-Submission: Check validation upon submission.
  2. Pre-Submission: Validate as users fill in, and promptly signify a successful validation.
Effective feedback informs users about erroneous fields and resolutions. Employ one or multiple of these strategies:
  • List incorrect fields with reasons atop the form
  • Mark erroneous fields in red
  • Show error messages adjacent to incorrect fields

Avoid disabling the submit button until validation is successful. If adopted, always visually explain the reason for its disabled state.

Effective Error Management

Always validate form submission success. Error-handling differs for Power Apps form controls and patch forms. For Power Apps controls, use OnSuccess and OnFailure properties. For patch forms, encompass the Patch function within an IfError function.

If an error arises, alert the user about the failed submission and its reason. Ensure the form remains accessible for correction.

Guard Against Unsaved Changes

Safeguard users from unintentionally exiting with unsaved data. Prioritize user confirmation when attempting to leave the form. Use a pop-up with the message: “Pending changes detected. Confirm form closure?” with options “OK” or “Cancel“.

Maintain Consistency with a Singular Form

Adopt a single form for record creation, editing, and viewing. This streamlines development, reduces maintenance efforts, and guarantees consistency. Adjust a Power Apps form mode using NewForm, EditForm, and ViewForm functions. Patch forms might necessitate extra coding to manually modify the DisplayMode of each control.
