How to pop up a numeric keyboard on iOS

Problem

A field in your form requires numbers to be entered, and it's inconvenient when the regular QWERTY keyboard pops up.

Solution

Configure a textbox so that on iOS devices the numeric keyboard will appear when the textbox is selected. Follow these steps in InfoPath 2010 or 2013:

1. In the properties of the field or the textbox, set Data type to either Number or Decimal.
    
   
    
2. In the properties of the textbox, click Format.
    
   
    
3. Be sure to deselect the digital grouping symbol checkbox, which is marked by default. The other default values can be kept or changed as follows: 
• Leave the Format as Number or change it to Percentage.
• Leave the Decimal Places at Auto (or zero works too).
