How to Remove the Thousands Separator

By default the RadMaskedNumericInput and RadMaskedCurrencyInput controls use a culture-aware thousands separator:

Example 1: AutoFillNumberGroupSeparators set to true which is by default

<telerik:RadMaskedNumericInput HorizontalAlignment="Center" 
                               Culture="en-US" 
                               EmptyContent="Enter digits" 
                               Mask="#9.0" 
                               SelectionOnFocus="SelectAll" 
                               SpinMode="PositionAndValue" 
                               TextMode="PlainText" 
                               UpdateValueEvent="LostFocus" 
                               Value="12345" /> 

If you need to remove the thousands separator, you can set the AutoFillNumberGroupSeparator property to False:

Example 2: Setting the AutoFillNumberGroupSeparators property to false

<telerik:RadMaskedNumericInput HorizontalAlignment="Center" 
                               AutoFillNumberGroupSeparators="False" 
                               Culture="en-US" 
                               EmptyContent="Enter digits" 
                               Mask="#9.0" 
                               SelectionOnFocus="SelectAll" 
                               SpinMode="PositionAndValue" 
                               TextMode="PlainText" 
                               UpdateValueEvent="LostFocus" 
                               Value="12345" />
