to simplify information management.

00:00:10

To start,

00:00:11

select the button within your gallery and configure its

00:00:14

on select property to capture the selected item.

00:00:18

In this step,

00:00:19

you will create a variable intended to store

00:00:21

the data associated with the clicked item.

00:00:23

We will cover the use of variables in greater

00:00:25

detail in an advanced section of the tutorial.

00:00:29

The formula used is as follows.

00:00:31

This formula assigns the selected items data

00:00:35

represented by this item to the variable wire task,

00:00:38

thereby allowing that data to be transferred to another screen.

00:00:42

Additionally,

00:00:43

it is necessary to navigate to the screen containing the

00:00:45

form as soon as the user clicks the button.

00:00:49

To do this,

00:00:49

combine two formulas using the semicolon operator

00:00:52

and add the following formula.

00:00:55

This command allows you to navigate to screen 3 with a fade transition effect,

00:01:00

creating a smooth and pleasant navigation experience for the user.

00:01:04

Next,

00:01:05

configure your form by setting its item property

00:01:08

to the variable var task.

00:01:10

This assignment enables the form to auto-populate

00:01:13

with the data of the selected gallery item.

00:01:17

Add two additional buttons,

00:01:19

one label cancel and the other save,

00:01:21

to handle the cancellation and submission of edits respectively.

00:01:25

Although layout optimization using multiple containers is recommended,

00:01:30

as explained in a dedicated tutorial,

00:01:33

We will simply insert these buttons here to save time.

00:01:37

Making sure to update the button text to clearly indicate their functions.

00:01:42

For the save button set its own select property with the following formula.

00:01:46

This formula submits the form name Form 3,

00:01:50

and sends the entered data to the appropriate data source.

00:01:53

Additionally,

00:01:54

in the on success property of the form,

00:01:57

that is,

00:01:58

the action triggered upon successful submission,

00:02:01

You must insert the following formula.

00:02:04

This command performs 3 combined actions.

00:02:07

It clears the variable VAR task to prevent data collision,

00:02:11

executes the back function to return to the previous screen,

00:02:15

and displays a success notification indicating

00:02:18

that the tasks were saved correctly.

00:02:21

The cancel button should be configured with the

00:02:23

following formula in its on select property.

00:02:26

This resets the form using reset form,

00:02:30

clears the variable var task once again,

00:02:33

and navigates back to the previous screen,

00:02:35

canceling any edits in progress.

00:02:38

Once these configurations are in place,

00:02:41

test the app to confirm that the

00:02:42

gallery button correctly captures the selected item.

00:02:46

And that the form accurately reflects the data passed through the variable.

00:02:50

Also confirmed that the submission and cancellation actions work as expected,

00:02:55

ensuring that both navigation and notifications are error free.

00:03:00

This tutorial has demonstrated how to link a form to

00:03:03

gallery by configuring a button to create a variable,

00:03:07

navigating between screens and handling

00:03:09

the submission or cancellation of changes

00:03:12

using simple and effective formulas.

00:03:15

In the final part of this tutorial,

00:03:17

we will explore how to add a new entry directly within the form

00:03:20

to further extend the capabilities of your Power App's application.
