When we present data, do not presen a modified data to the user. For example, the amount is 10,000 yuan. If we display "10000" directly, it may cause the user to see a thousand or 100,000, causing the user's reading data. If we output 10,000 yuan to "NT $ 10,000", we will not only make more good reading, but also make users reduce the chance to make mistakes.
The following screens are equissitive results:
The above data is easier to read by using the DataGrid web control to be recorded in colors. To modify the output of the field, just set the DataFormatString property of the field; use the syntax as follows:
DataFormatString = "{0: Format string}"
We know that the {0} represents the data itself in the dataformatstring, and the format string behind the colon depends on the format that wants the data display; additionally, you can specify the number of digits to display after the specified format symbol. For example, the original data is "12.34", if the format is set to {0: N1}, the output is "12.3". The common value formats are shown in the following table:
Format string information
"{0: C}" 12345.6789 $ 12,345.68
"{0: C}" -12345.6789 ($ 12,345.68)
