iOS Question B4i Question on numeric keypads for iPad

I need to trigger specific keypads for TextView inputs and am using the followings statements-

txt1.KeyboardType = txt1.TYPE_NUMBER_PAD <-- for integer input, and

txt1.KeyboardType = txt1.TYPE_DECIMAL_PAD <-- for decimal input

This works fine on iPhone but not on iPad. On iPad I always get the full keypad with numbers and punctuations. I have iOS 8.2 on both devices.

Is there anyway to have iPad bring up the correct keypad as iPhone does?
