TextField Set Help Needed

Hi,
I have a window with 5 TextFields in a TextField Set (see below):

TextField1(0)
TextField1(1)
TextField1(2)
TextField1(3)
TextField1(4)

I need to ensure that TextField1(0) can only accept numbers - without affecting any of the other TextFields in the set.

If I use a KeyDown event handler, it works on ALL of the TextFields, and not just TextField1(0).

Any ideas how I can make it only work for TextField1(0).

I am thinking maybe :

if index = 0 then

But I am not at my computer at the moment, so cannot try it out.

Thank you all in advance.

In your keydown handler:

If index = 0 Then //add a mask to only allow numbers else //add code for how the other members of the control set should behave. end if

I thought so, just wanted to check.

Thank you very much :slight_smile:

Another thing to consider is that, if you consistently want different behavior for TextField1(0) than the other fields, maybe it doesn’t belong in the control set but rather as a separate control

I agree, but my app got bigger and bigger and bigger, and before I knew it, it was too late and too complex to change. lol

Thank you all.

In the future you might want to consider creating a custom TextField subclass. This would contain an attribute indicating what type of data the user is allowed to enter.

I have one I created that allows

  • plain text
  • forced upper case
  • currency (US)
  • Date
  • Date/Time
  • Time
  • valid email address
  • Integer Numbers
  • Floating Point
  • Password
  • Phone # (US)
