Introduction to Patch vs SubmitForm Function in PowerApps

When building applications in PowerApps, developers often need to create, update, or modify records in data sources like SharePoint, Dataverse, or SQL Server. This is where the Patch vs SubmitForm Function in PowerApps debate arises. While both are used to save or modify data, they function very differently under the hood and cater to specific design scenarios.

In this article, you will not only understand their syntax and usage but also when and why to choose one over the other in real-world development.

Understanding the SubmitForm Function in PowerApps

What Does SubmitForm Do?

The SubmitForm(FormName) function is used to submit a form’s data to its connected data source. It’s primarily used with EditForm or NewForm controls.

Features of SubmitForm:

• Automatically includes all fields in the form.
• Handles form validation.
• Triggers the OnSuccess or OnFailure events.
• Requires a form control to be used.

Syntax:

SubmitForm(Form1)

Advantages:

• Best suited for standard form submissions.
• Simplifies data entry processes.
• Handles mode (Edit/New) automatically.

What is the Patch Function in PowerApps?

Patch Function Defined

The Patch function is a more flexible tool that allows you to update or create records without a form control. It offers developers fine-grained control over which fields to update and what values to assign.

Patch Syntax:

Patch(DataSource, Defaults(DataSource), {Title: "New Item", Description: "Details here"})

Features of Patch Function:

• Works with and without form controls.
• Can update single or multiple fields.
• Can create new records or update existing ones.
• Gives full control over which data gets written.

Key Differences: Patch vs SubmitForm Function in PowerApps

Patch vs SubmitForm: Feature Comparison

Feature	Patch	SubmitForm
Requires Form Control	❌	✅
Field-level control	✅	❌
Built-in validation	❌	✅
Flexible data updates	✅	❌
OnSuccess/OnFailure events	❌ (manual)	✅ (automatic)

When analyzing Patch vs SubmitForm Function in PowerApps, it becomes clear that Patch offers more control, whereas SubmitForm simplifies the process.

When to Use SubmitForm in PowerApps

Ideal Use Cases for SubmitForm

• When using EditForm or NewForm controls.
• For quick form submissions with minimal customization.
• When automatic validation is required.
• For simple CRUD operations without complex logic.

Example:

SubmitForm(EditForm1)

Benefits:

• Requires less code.
• Automatically manages field mapping and error handling.
• Excellent for rapid app development.

When to Use Patch Function in PowerApps

Ideal Scenarios for Patch

• When you need to update data outside of a form.
• When you only want to update specific fields.
• When working with collections, custom controls, or conditional logic.
• Advanced scenarios like:
  • Conditional data manipulation
  • Complex nested records
  • Integration with timers or parallel operations

Example:

Patch(Employees, LookUp(Employees, ID=123), {Status: "Active"})

---

Practical Examples of SubmitForm and Patch

SubmitForm Example:

NewForm(Form1);
Navigate(EditScreen);
...
SubmitForm(Form1);

This is straightforward and leverages PowerApps’ form-based architecture.

Patch Example:

Patch(Tasks, Defaults(Tasks), {
    Title: txtTitle.Text,
    Status: ddStatus.Selected.Value,
    DueDate: dtDueDate.SelectedDate
});

This approach gives full control over each field and enables customization beyond the limitations of form controls.

Error Handling with Patch vs SubmitForm Function in PowerApps

SubmitForm:

• Comes with OnSuccess and OnFailure properties.
• Makes it easy to handle errors on screen.

Form1.OnFailure: Notify("Submission failed", NotificationType.Error)

Patch:

• Requires manual error capture using IfError.

IfError(
  Patch(Tasks, LookUp(Tasks, ID=123), {Status: "Completed"}),
  Notify("Error updating task", NotificationType.Error)
)

Understanding Patch vs SubmitForm Function in PowerApps is critical when error handling is a primary requirement. SubmitForm provides built-in simplicity, while Patch needs custom implementation.

---

Performance Considerations

SubmitForm Performance:

• Efficient when submitting the entire record.
• Slower if only a few fields need to be changed.

Patch Performance:

• Better performance when updating only necessary fields.
• Ideal for large datasets or high-frequency updates.

Example for Performance Optimization:
Use Patch with collections to batch update multiple items instead of multiple SubmitForm calls.

---

Best Practices in Using Patch and SubmitForm

SubmitForm Best Practices:

• Always check form validity before submission.
• Use ResetForm after submission for user experience.
• Utilize OnSuccess for navigation or feedback.

Best Practices for Patch:

• Use IfError or IsError for error trapping.
• Prefer Patch for custom forms or advanced logic.
• Test performance with larger datasets.

Conclusion: Choosing Between Patch vs SubmitForm Function in PowerApps

The choice between Patch vs SubmitForm Function in PowerApps depends on your app’s complexity, performance needs, and user experience goals. While SubmitForm is great for straightforward form-based apps, Patch shines when flexibility and control are needed.

To summarize:

• Use SubmitForm for quick development with built-in validation and event handling.
• Use Patch when working with dynamic controls, complex logic, or selective field updates.

Mastering both functions gives you the flexibility to build powerful, efficient, and user-friendly PowerApps solutions.
