teclado numeric

[oamo...@gmail.com]

Quiero hacer una calculadora y no encuentro ningún objeto que pueda usar como teclado numérico.¿Existe tal objeto o hay que hacer una matriz de botones?

You can put buttons in a Table arrangement      or you can use a Canvas with a grid overlay  with an arrangement like:

7   8   9   -

1   5   6   +

1   2  3  Enter

0      

AND this forum discussion shows how you can set up the grid on the canvas, place the numbers etc.  https://groups.google.com/forum/#!searchin/mitappinventortest/grid$20and$20canvas/mitappinventortest/c7xYUTKFG_Q/hlwOMxsNm6oJ

Did this work for you>

if you want to use a textbox for input, just set NumbersOnly = true to get a numeric keyboard

I generally use a combination of horizontal and vertical screen arrangements to make a numeric keypad.

It is more flexible than a table arrangement if the buttons are not all the same size.
