Acceptence of characters in string control
Hello All,
i need to create array of strings (control) which will accept only numeric characters, and not letters.
For string control which is not array, i already did it, using some examples from this forum.
This works fine but there is problem by using delete, backspace and arrow buttons.
But, when string control is changed in to array of string controls, then i can type anything, not just numbers...
Can someone advise how to proceed?
Thanks.
You can do the same by means of a dynamic event registered from the array element reference.
Don't forget to catch Key Repeat? events (when user holds a key).
And you also need to catch Value Change events (when user does a copy-paste).

Because later will be accepted for example 0-9, '-',':', and some other characters, posibly couple of letters.
That's why i need to have limitation which character can be enter in string, and not able to use numeric array.
Then just do this:

I think OP means later the array of strings control must accept for "example 0-9, '-',':', and some other characters, possibly couple of letters".
So, that would require a strings.
One more thing..
Could you please explain me why this work when we use dynamic user event and not when we just put array in event structure, and chose key down?

I'm asking because i use actor framework, and not sure how to implement this array element property node.
Thanks.
