If by design your PowerApps app is not supposed to have any text input but numbers then it might be a good idea to “disable” a native phone keyboard and add buttons as an on-screen numeric pad.

The only downsides of this method are a bit of additional code and taking screen estate. However, it creates a smooth and consistent user experience.

To disable the keyboard all text input fields should have DisplayMode set to:

DisplayMode.Disabled

A rough preview:

The OnSelect code for each numeric button would be (example for button “1”):

UpdateContext({varTicketInput: varTicketInput & "1"})

TextInput1 Default value must be set to:

varTicketInput

X button (to start over) OnSelect code:

UpdateContext({varTicketInput: ""})

OK button OnSelect code:

Set(
    TicketNum,
    TextInput1.Text
)

That TicketNum global variable can be used later on any screen.

NICE TO HAVE

To make your app even better I would recommend disabling some buttons at certain conditions:

• X button is disabled when there is no input yet
• OK button is disabled when there is no input yet
• 0 (zero) button is disabled when there is no input yet
• also let’s limit the length of the input to 5 digits.

DisplayMode code for X button, OK button, “0” button:

If(
    varTicketInput = "",
    DisplayMode.Disabled,
    DisplayMode.Edit
)
