Hi Anupong,
Thank you for using Syncfusion product.
Query 1: How to display integer values without periods in SfNumericTextBox.
Displaying numbers with regional separators(periods) is the behaviour of SfNumericTextBox. And currently we do not have any support to display without any periods. You can use Xamarin.Forms Entry with Numeric keypad for your requirement. Here we have prepared and attached a sample for your reference please download it from the below link.

Query 2: Using “NO” in FormatString
SfNumericTextBox has three formats (“N”,” P”,”C”) and one custom format. If we give any format string out of following characters{“N”,”n”,”P”,”p”,”C”,”c”} NumericTextBox will take it as custom format and display the given character or string after the entered value in the text box.
Please let us know if you have any other queries
Regards,
Pavendhan K.
