You don't need to go through this stress at all. Since you have the keyboard changed to numeric, simply let the OS determine the layout.

Now when you get the Entry.Text, simply replace the occurrences of (,) to (.). To make it real-time, do this in the Entry.TextChanged Event.

Entry.Text?.Replace(',', '.');

Hope this helps.

The "?" ensures that if the Entry.Text is NULL, the code doesn't break. – waletoye Dec 15 '18 at 08:27

When change language of device Android (Samsung S7 Edge), keyboard can't change "." to "," . So that can't input value "1,23". I fixed it, thanks you. – Huu Bao Nguyen Dec 28 '18 at 11:37
