The Edit form control

Insert → Edit form
Set DataSource to your tickets list
Power Apps auto-generates one card per column

Power Apps Edit Form on a tablet with Title, Status, Priority, Assigned To, and Due Date input cards.

Form modes: New / Edit / View

Three Edit Form states side by side showing blank FormMode.New, pre-filled FormMode.Edit, and read-only FormMode.View.

New, blank form, ready to create a row
Edit, pre-filled with an existing row
View, read-only display

SubmitForm() and the lifecycle

Save button runs SubmitForm(frmTicket)
Power Apps validates and writes to your data source
The form fires OnSuccess or OnFailure

Flowchart from Save tap through SubmitForm(), SharePoint write, OnSuccess checkmark, and an OnFailure error branch.

OnSuccess, OnFailure, OnReset

Three color-coded blocks stacked vertically: green OnSuccess with Notify, Refresh, Navigate; red OnFailure with Notify error toast; gray OnReset clears form to defaults.

OnSuccess, show a toast, refresh the gallery, navigate back
OnFailure, show an error toast
OnReset, runs when the form is cleared

Refresh(), the forgotten step

Galleries don't auto-refresh after a submit
Add Refresh(Tickets) to the form's OnSuccess
Skip this and the new row looks invisible

Two tablets side by side: left shows gallery without Refresh where new ticket is missing, right shows gallery with Refresh where new ticket appears highlighted at top.

ResetForm(), the cancel path

Two New ticket forms showing leftover data before ResetForm() and a blank form ready for entry after reset.

ResetForm(frmTicket) blanks every field
Put it on a Cancel button, never on OnSuccess
OnSuccess already navigates away, NewForm blanks the form next time

Patch() is out there too

Patch(DataSource, record, changes) writes without a form
Useful for bulk updates or single-field changes
A more advanced tool, beyond this course

Patch(
  Tickets,
  ThisItem,
  { Status: "Resolved" }
)

What you'll build

Edit Form with prefilled ticket fields, dropdowns, person picker, DueDate, and a green Save button at the bottom.

Add an Edit Form bound to your data source
Handle success and failure after submit
Add New and Cancel buttons for the full form lifecycle

Let's practice!
