Re: Placeholder for form fields input
See the sample app attached. Go to https://us.create.powerapps.com/studio/# and then Open, and select the file (after you download it).
Basically, I've placed a Label over a TextInput. Using a variable, they will toggle the visibility of one of the control's, while the other's visibility is the inverse. Meaning - they won't ever be visible at the same time.
OnChange function for TextInput
UpdateContext({locShowLabel:true})
Visible Properties:
- Label: locShowLabel
- TextInput: !Label.Visible
Then the Text property of the Label is the Text function we described, while the TextInput is a number input mechanism only.
Text(Value(TextInput1.Text), "[$-en-US]$#,### USD")
Hope this helps! You'll obviously need to adjust to your needs. FYI: you can copy controls from Studio session to Studio session, if you want to copy these over as starting points.
