Modern Controls Textbox fires onChange Event altough nothing was changed

Posted on by SLMR 518 Super User 2025 Season 1
Hello,
I have an model-driven App with some custom pages.
 
On the custom pages i have gallery with some TextBoxes (modern Controls) and i handle the onChange Event.
This worked fine for the last year. The event only fired if the text was really changed.
 
Now i started to overwork the pages.
And for some reasons all textboxes fire the event, if i just enter the textbox and leave them, without changing anything.
This also happen if i create a new textbox.
 
If i add a textbox (classic design) than it works as it is intended and only fires the event when a change occured.
 
In the Live System where still the old Pages is active it still works as it should.
 
Any idea what can cause the problems that controls start behaiving this way?

    HI @SLMR
     
    What mode are the modern input boxes in? KeyPress or other?
