Hello @Manu Michael Samuel , Welcome to Microsoft Q&A,
While Textbox visibility Collapsed textchange event not working
It's by-design that textchange event not working when set the TextBox
Visibility collapsed. If you set as collapsed, the element will not display the element, and do not reserve space for it in layout. TextChanging
will be not triggered.
