Syntax

Visual Basic

'Declaration
 
Public Shared Function CalcDefaultDoubleMask( _
   ByVal formatProvider As IFormatProvider, _
   ByVal integerDigits As Integer, _
   ByVal fractionDigits As Integer, _
   ByVal allowNegatives As Char _
) As String

C#

public static string CalcDefaultDoubleMask( 
   IFormatProvider formatProvider,
   int integerDigits,
   int fractionDigits,
   char allowNegatives
)

Parameters

formatProvider

Format provider to use to construct a default mask with. Can be a CultureInfo or a NumberFormatInfo instance.

integerDigits

Number of digits in integer section. -1 means use a default. Can be 0 in which case there won't be an integer portion.

fractionDigits

Number of digits in fraction section. -1 means use one specified by culture info. Can be 0 in which case there won't be fraction section.

allowNegatives

If '-' or '+' then negative numbers are allowed. '-' specifies that the minus sign should be displayed only when the number is negative. '+' specifies that the plus or minus sign will always be displayed depending on whther the number is negative or positive. If this parameter is any other character then it's ignored.

Return Value

Mask as a string.

Remarks

Typically there is no need for you to directly call this method. If the ValueType is set to Double or Float, the XamMaskedInput and derived editors will call this method to calculate the mask if none has been explicitly set. Also if you want to explicitly set the mask to make use of culture sensitive double/float mask then use one of the double tokens as documented in the table listing all the mask tokens in the help for Mask property.
