UserDefinedFormat Property (DateTimeCellType)
Example 


Gets or sets the format used when the date-time format is user-defined.
Syntax
'Declaration
 
Public Property UserDefinedFormat As String
'Usage
 
Dim instance As DateTimeCellType
Dim value As String
 
instance.UserDefinedFormat = value
 
value = instance.UserDefinedFormat
public string UserDefinedFormat {get; set;}

Property Value

String containing the format specifiers
Exceptions
ExceptionDescription
System.ArgumentException Specified format is not valid
Remarks

The formats supported are in the DateTimeFormatInfo object that can be found in the Microsoft .NET framework SDK documentation. Discussion of these formats are in the date-time formats and Custom DateTime Format Strings topics in the Microsoft .NET Developer's Guide. The fractional seconds are not supported in the DateTimeCellType (though they are in the GeneralCellType).

Briefly summarized, you can use any of the following custom date-time format specifiers:

Format Specifier Description
d, dd numeric day
ddd string of abbreviated day
dddd string of full day name
f,ff, ... most significant digits
of the seconds fraction
F,FF, ... most significant digits
of the seconds fraction
without trailing zeros
h, hh hour (1 to 12)
H, HH hour (1 to 24)
m, mm numeric minutes
M, MM numeric month
MMM, MMMM abbreviated, full month name
s, ss numeric seconds
t, tt AM/PM designated
y, yy, yyyy numeric year
z, zz, zzz time zone offset

Example
This example specifies the strings to use for the day names and month names when the format is "dddd MMMM d, yyyy".
