Namespace: Avalonia.Controls.Automation.Peers

This namespace exposes the Avalonia automation peers used by TreeDataGrid for accessibility tools, screen readers, and UI automation.

Functional Groups

Grid Root Peer

• TreeDataGridAutomationPeer

Row and Cell Peers

• TreeDataGridRowAutomationPeer
• TreeDataGridCellAutomationPeer
• TreeDataGridCheckBoxCellAutomationPeer

Header Peers

• TreeDataGridColumnHeaderAutomationPeer
• TreeDataGridColumnHeadersPresenterAutomationPeer

Guidance

Most applications consume these types indirectly through the built-in TreeDataGrid templates and realized controls.

Use them directly only when you are:

• extending TreeDataGrid control behavior
• validating automation-provider behavior in tests
• customizing accessibility contracts for derived controls
