Accessibility in Xamarin TreeView (SfTreeView)
3 Sep 2020 / 1 minute to read
The TreeView control has built-in
AutomationId for inner elements. The AutomationId API allows the automation framework to find and interact with the inner elements of the TreeView control. To keep unique AutomationId, these inner element’s AutomationIds are updated based on TreeView control
For example, if we set TreeView’s AutomationId as “Automation” then Automation framework will interact with expander icon of TreeNodeItem as
AutomationItem1 Expander. Here, along with the control’s AutomationId, index of an item will also be added for differentiating each TreeNodeItem expander.
|Expander View||ControlAutomationId+Item+ItemIndex Expander||AutomationItem1 Expander
where Automation represents Control AutomationId, Item1 represents Item text appended with item index which has been generated based on item position and Expander represents the expander dropdown icon.
The following image denotes the AutomationIds of inner elements.
