Panos,

Thank you for the suggestion!   That worked out well!   For anyone
interested, here's the snippet for formatting a phone number as you type in
a mobile native field control:

//this assumes that the mobileControl type for Android is "multiline" and
the mobileSetKeyboardType has been set to "email"

on inputTextChanged
  put mobileControlTarget() into pField
  put mobileControlGet(pField,"text") into pText

  if pField = "phoneNumber" then
    put "" into fText
    put numbersOnly(pText) into pText

    if char 1 of pText = "1" then
      put "" into fText
      mobileControlSet "phoneNumber","text",fText
      androidGoLastChar "phoneNumber",fText
      put fText into dataEntered["phone"]
      exit inputTextChanged
    end if

    if the number of chars in pText < 4 then
      put pText into fText
      mobileControlSet "phoneNumber","text",fText
      androidGoLastChar "phoneNumber",fText
    else
      if (the number of chars in pText > 3) then
        put "(" & char 1 to 3 of pText & ")" into char 1 to 3 of fText
        put " " & char 4 to 6 of pText after fText
      end if
      if the number of chars in pText > 6 then
        put "-" & char 7 to 10 of pText after fText
      end if

      mobileControlSet "phoneNumber","text",fText
      androidGoLastChar "phoneNumber",fText
    end if
  end if
end inputTextChanged

function numbersOnly pNum
  //returns only the numbers in pNum
  put "" into fNum
  repeat for each char c in pNum
    if isNumber(c) then
      put c after fNum
    end if
  end repeat

  return fNum
end numbersOnly

on androidGoLastChar mControl,xText
  if ("Android" is in the platform) then
    mobileControlSet mControl,"selectedRange",(the number of chars in
xText+1,0)
  end if
end androidGoLastChar


Thank you!

Subject: Re: Cursor Placement in MobileControl Hello Dan,

I take it you are formatting the text in inputTextChanged?

Unfortunately yes, on Android calling

mobileControlSet "phoneNumber","text", pText

puts the cursor in the beginning of the text:

RE using the selectedRange with mobile native controls, I think this
property is supported only on multiline input fields. So I suppose you could
make the fields to be multiline and give it a try.

Kind regards,
Panos
