Hi all - today one of my clients sent me a screenshot with an error message. I tried to reproduce it and found one unexpected result.
Let's say I have a layout with 2 textfields - in my code they are B4XView.
1 - txtProvider
2 - txtProviderName
txtProvider has Keyboard Type - Number_Pad
txtProviderName has Keyboard Type - Default.
I can't type any letters into txtProvider - on a keyboard I see only numbers. Now how to do the trick - type a string like Jane Doe into txtProviderName, copy it and Past it into txtProvider - it works. Then when I click Submit my code crashes because I don't expect any letters in txtProvider (my code assigns a value from txtProvider to the ProviderID variable which is Int).
I tried to do the same trick with the Android version of my app where I have the same 2 EditBoxes - it's impossible to Past a string with letters into txtProvider.
My question is - how to prevent it from happening in the iOS version? I understand that I need to add a validation...
