Learn how to detect if a MatDialog is open in Angular using MatDialog service and its openDialogs property or event listeners.

85 views

Knowing if a MatDialog is open can be achieved by using Angular's MatDialog service. Check the number of open dialogues through the `openDialogs` property of MatDialog. If `dialog.openDialogs.length > 0`, it indicates that at least one MatDialog is currently open. Alternatively, listen for the `afterOpened()` or `afterClosed()` events of MatDialog to keep track of dialog state changes in real-time, ensuring you can programmatically determine whether a MatDialog is open at any given time.
