Value Box Formatting Options (version 21)

updated 2 yrs ago

The Value Box control can be configured to display the Value, Timestamp, or Quality of tag by using the 'ValueFormat' property. Parameters are formatted using C#'s string.Format() method.

Value

By default, the value box is set to display the value of the tag with 2 decimals places, {Value:N2}, where N is a single alphabetic character called the format specifier and 2 is an optional integer called the precision specifier. Below are the supported formats.

Format Specifier	Name	Description	Example
C	Currency	A currency value that supports all numeric types	Raw Value: 123.456 Format: {Value:C2} Result: $123.46
D	Decimal	Supports integral types only	Raw Value: 123 Format: {Value:D4} Result: 0123
E	Exponential	Exponential notation that supports all numeric types	Raw Value: 123.456 Format: {Value:E3} Result: 1.235e+002
F	Fixed-Point	Number of decimal digits that supports all numeric types	Raw Value: 123.456 Format: {Value:F1} Result: 123.5
G	General	Number of signicant digits that supports all decimal types	Raw Value: 123.456 Format: {Value:G3} Result: 123
N	Number	Number of decimal places that supports all numeric types	Raw Value: 123.456 Format: {Value:N2} Result: 123.46
P	Percent	Number multiplied by 100 that supports all numeric types	Raw Value: 123.456 Format: {Value:P3} Result: 12345.600%
X	Hexadecimal	A hexadecimal string that supports integral types only	Raw Value: 123 Format: {Value:X3} Result: 07B

Time

DateTime formatting can be achieved using the format {Time:Pattern} where Pattern is supplied such that

yyyy = 4 digit year
MM = number of month
dd = number of day
HH = hours using a 24 hour clock
hh = hours using a 12 clock
mm = minutes
ss = seconds
tt = AM/PM

Ex: {Time:M/dd/yy hh:mm tt} = 1/01/21 12:00 AM

Additional formatting options can be found by searching for C# custom date time formats. If no pattern is specified, the entire timestamp will be shown including the GMT offset.

Ex: 1/1/2021 12:00:00 AM -04:00

Quality

Setting the ValueFormat property to {Quality} will display a readable quality within the value box such as Good or Uncertain. Any values that have a bad quality will appear as a No Data regardless of the formatting.
