Control.ControlAccessibleObject.RaiseLiveRegionChanged Method

Definition

Raises the LiveRegionChanged UI automation event.

public override bool RaiseLiveRegionChanged ();

Returns

true if the operation succeeds; otherwise, false otherwise.

Exceptions

The owner control is not a live region.

Remarks

For this method to be effective, the control must implement the System.Windows.Forms.Automation.IAutomationLiveRegion interface, and its LiveSetting property must return either AutomationLiveSetting.Polite or Assertive. In addition, the application must be recompiled to target .NET Framework 4.8 or opt in to this feature by using compatibility switches.
