Set dataformatstring in gridview

Source: Internet

The syntax of the dataformatstring attribute is as follows:

Dataformatstring = "{0: Format String }"

We know that {0} In dataformatstring represents the data itself, while the format string after the colon represents the format that we want the data to display; in addition, after the specified format symbol, you can specify the number of digits to be displayed in decimal places. For example, if the original data is "1.56" and the format is set to {0: N1}, the output is "1.5 」. The common numeric format is shown in the following table:

Format String input result
"{0: c}" 12345.6789 $12,345.68
"{0: c}"-12345.6789 ($12,345.68)
"{0: d}" 12345 12345
"{0: D8}" 12345 00012345
"{0: e}" 12345.6789 1234568e + 004
"{0: E10 }" 12345.6789 1.2345678900e + 004
"{0: F }" 12345.6789 12345.68
"{0: F0 }" 12345.6789 12346
"{0: g}" 12345.6789 12345.6789
"{0: G7}" 123456789 1.234568e8
"{0: n}" 12345.6789 12,345.68
"{0: N4}" 123456789 123,456,789.0000
"Total: {0: c}" 12345.6789 total: $12345.68

The commonly used date formats are shown in the following table:

Format description output format
D. Simplified Date Format: mm/DD/YYYY
D detailed Date Format: dddd, Mmmm DD, yyyy
F full format (long date + short time) dddd, Mmmm DD, yyyy hh: mm
F complete Date and Time Format (long date + long time) dddd, Mmmm DD, yyyy hh: mm: SS
G General Format (short date + short time) mm/DD/YYYY hh: mm
G General Format (short date + long time) mm/DD/YYYY hh: mm: SS
M, M month/day format mmmm dd
S moderate Date and Time Format: yyyy-mm-dd hh: mm: SS
T simplified time format hh: mm
T detailed time format hh: mm: SS note: in ASP. NET 2.0, set htmlencode to false; otherwise, dataformatstring does not work.
Example: <asp: boundfield datafield = "subtime" dataformatstring = "{0: f}" headertext = "subtime" sortexpression = "subtime" htmlencode = "false"/>

This document is obtained from the Internet. In practice today, because the date format is used and only the "hour: minute: Second" format is displayed, dataformatstring is set to {0: hh: mm: SS}, the result shows that if it is two o'clock P.M., it should be displayed as "14:00:00" in twenty-four hour format, but the result is displayed as "02:00:00". Set dataformatstring to {0: hh: mm: SS. This is a small difference, by the way.
