I just added modalpopextender control for the save dialog box. The way it is supposed to work is that when the user let’s say Save the changes, the message box opens and the text of the message is read by the screen reader. When they select the buttons in the message box, such as Yes, No or Cancel, the message box closes.
This should be the behavior across the entire application.
There will be a message box like the one below. Try it with a keyboard. The focus is not lost.
The user should not leave the message box until clicking buttons in the message box. Even they cannot access any other stuff on the page unitl they they make a selection in the message box.
Please assist me with this issue.
Thank you,
