Introduction to Galleries and Forms

PowerApps offers two major visual components to display and interact with data: galleries and forms. Galleries are used for data browsing, while forms are used to view, edit, or create records. Together, galleries and forms bound to data in PowerApps serve as a complete solution for building functional business applications.

Understanding Data Binding in PowerApps

Data binding refers to the process of connecting app controls to a data source. In PowerApps, controls like Gallery, EditForm, and DisplayForm are designed to consume records from connected data sources such as SharePoint lists, SQL tables, Excel sheets, or Dataverse entities.

Using Galleries and Forms Bound to Data in PowerApps, you can create applications that feel like native apps with automatic updates, filtering, and dynamic layouts.

PowerApps Galleries Bound to Data

Types of Galleries in PowerApps

• Vertical Gallery
• Horizontal Gallery
• Flexible Height Gallery
• Blank Gallery

All these galleries can be bound to data using the Items property:

Items = Filter(Employees, Department = "Sales")

This binds the gallery to filtered employee records where the department equals “Sales.”

Key Properties for Data Binding in Galleries

• Items: Defines the source collection or data set.
• TemplateSize: Adjusts layout spacing.
• WrapCount: For horizontal layouts.
• Default: Used in linked controls to identify the selected record.

With galleries and forms bound to data in PowerApps, a selected item in a gallery can directly feed into a form using the Gallery.Selected property.

Forms Bound to Data in PowerApps

Types of Forms

• DisplayForm: View-only.
• EditForm: Edit existing records.
• NewForm: Create new records.

Bind a form to a data source like this:

DataSource = 'Employee Records'

And to view/edit specific records:

Item = Gallery1.Selected

Important Form Properties

• DataSource: The table or list connected.
• Item: The selected or focused record.
• Mode: FormMode.New, FormMode.Edit, FormMode.View.
• OnSuccess / OnFailure: Post-submission logic.

Connecting Data Sources

To use galleries and forms, you first need to connect PowerApps to your data source:

1. Go to Data > Add data
2. Select SharePoint, SQL, Excel, Dataverse, etc.
3. Choose or create a new connection.
4. Bind your gallery or form using the Items or DataSource property.

Customizing Galleries with Bound Data

Use bound fields to show key data:

ThisItem.Title
ThisItem.'Employee Name'

You can also apply formulas like:

If(ThisItem.Status = "Active", Green, Red)

This dynamic rendering makes galleries and forms bound to data in PowerApps not only functional but visually intuitive.

Using Forms for CRUD Operations

Create Record

NewForm(EditForm1);
Navigate(FormScreen)

Update Record

SubmitForm(EditForm1)

Delete Record

Remove('Employee Records', Gallery1.Selected)

Forms bound to data allow seamless creation and modification of records within your app.

Master-Detail Layout Using Galleries and Forms

One of the most popular use cases of galleries and forms bound to data in PowerApps is the master-detail layout:

• Gallery (master) on the left.
• Form (detail) on the right.

When you select a record from the gallery, the form updates automatically using:

Item = Gallery1.Selected

This pattern is especially useful in CRM, HR, and ticketing systems.

Conditional Formatting in Bound Galleries and Forms

Add visual indicators based on data values:

Color = If(ThisItem.Priority = "High", Red, Black)

In forms:

DisplayMode = If(User().Email = ThisItem.ManagerEmail, DisplayMode.Edit, DisplayMode.View)

Such conditional behavior makes galleries and forms bound to data in PowerApps highly adaptive.

Delegation Considerations

When using large data sources, be aware of delegation limits. PowerApps only pulls the first 500 (default) or 2000 (configurable) records unless you use delegable functions like:

• Filter
• LookUp
• Search (for some sources)

Non-delegable queries may result in incomplete gallery or form data.

Performance Optimization Techniques

1. Use delegable queries.
2. Minimize control count on one screen.
3. Use Concurrent() to load data in parallel.
4. Avoid nested galleries where possible.
5. Use With() for temporary variables in forms.

Following these tips keeps your galleries and forms bound to data in PowerApps snappy and scalable.

Responsive Design with Galleries and Forms

Design your UI using:

• Relative positioning (X, Y, Width, Height based on screen size)
• Containers and flex layout
• Visible and DisplayMode logic for conditional rendering
• Orientation-aware logic:

If(App.Width > App.Height, "Landscape", "Portrait")

Make sure your galleries and forms bound to data in PowerApps look great on desktop, tablet, and mobile.

Security and Data Validation

Security

• Use SharePoint roles, Dataverse security roles, and conditional visibility.
• Use logic like:

Visible = User().Email = ThisItem.ManagerEmail

Validation

Add validation to forms:

DisplayMode = If(IsBlank(DataCardValue1.Text), DisplayMode.Disabled, DisplayMode.Edit)

OnSuccess/OnFailure events provide control over what happens after form submission.

Common Errors with Galleries and Forms Bound to Data

1. Invalid Data Source: Ensure connections are set correctly.
2. Blank Forms: Check the Item property.
3. Non-delegable Warnings: Rewrite queries using delegable functions.
4. Slow Loading: Avoid complex nested controls and use Concurrent().
5. Write Failures: Missing permissions or incorrect form mode.

Conclusion

Galleries and Forms Bound to Data in PowerApps empower makers to create highly functional, data-driven applications. Whether you’re building a ticketing app, HR portal, or sales dashboard, understanding how to bind and use these components effectively will elevate the user experience and functionality of your app.

By using best practices such as conditional formatting, delegation-aware filtering, responsive design, and clean CRUD integration, you can build apps that not only work well but scale efficiently across departments and organizations.
