2. Creating and Configuring Forms in PowerApps

Forms are essential for capturing structured data from users.

2.1 Types of Forms in PowerApps

🔹 Edit Form – Used for entering and updating data in a connected data source.
🔹 Display Form – Shows read-only information from a data source.

2.2 How to Create a Form?

1️⃣ Go to Insert > Forms > Edit Form
2️⃣ Set the DataSource property to your connected data source (e.g., SharePoint, Dataverse, SQL)
3️⃣ Customize fields using the right panel

Example: Creating an Employee Registration Form

1. Insert an Edit Form.
2. Set the DataSource property: Employees
3. Click Edit Fields > Add necessary fields (Name, Age, Department, Email).
4. Insert a Submit Button and set its OnSelect property: SubmitForm(EditForm1)
5. Insert a Success Label with Visible property: EditForm1.Valid

3. Handling Input Validation and Errors

Validation ensures that users enter correct and required information before submitting a form.

3.1 Required Field Validation

To make a field mandatory, check if it is empty using an If() statement.

Example: Validate Name Input

If(IsBlank(TextInput1.Text), Notify("Name is required!", NotificationType.Error))

3.2 Email Format Validation

To check if a valid email is entered, use the IsMatch() function.

Example: Validate Email Address

If(
   !IsMatch(TextInput2.Text, "^[\w-\.]+@([\w-]+\.)+[\w-]{2,4}$"),
   Notify("Enter a valid email!", NotificationType.Error)
)

3.3 Phone Number Validation

Allow only numeric values using IsNumeric().

Example: Validate Phone Number

If(
   !IsNumeric(TextInput3.Text) || Len(TextInput3.Text) < 10,
   Notify("Enter a valid phone number!", NotificationType.Error)
)

3.4 Date of Birth Validation

Ensure the user is above 18 years.

Example: Validate Age

If(
   DateDiff(DatePicker1.SelectedDate, Today(), Years) < 18,
   Notify("User must be 18 or older!", NotificationType.Error)
)

4. Storing and Submitting Form Data

Once input validation is passed, we need to store the data in a database.

4.1 Submitting Data to a Data Source

Use the SubmitForm() function to save form data.

Example: Submit Form to SharePoint

SubmitForm(EditForm1)

4.2 Storing Data in a Collection (Temporary Storage)

Sometimes, we may not want to directly submit data but store it temporarily in a Collection.

Example: Add User Input to a Collection

Collect(UserData, {Name: TextInput1.Text, Email: TextInput2.Text})

4.3 Clearing a Form After Submission

Use ResetForm() after submitting data to clear the form fields.

Example: Submit and Reset Form

SubmitForm(EditForm1);
ResetForm(EditForm1)
