Use of dataformatstring in gridview

Format the gridview with dataformatstring
Display Data in the gridview. If the data to be displayed has multiple decimal places, you just want it to display only two decimal places. in Delphi, you can simply use displayformat. net, after checking msdn for half a day, I found that dataformatstring can be used to implement this function, but how to set it does not work. Finally, I found that because 2.0 is for security considerations, you must also set htmlencode = false to make dataformatstring take effect.
Leave a mark. You don't need to waste more time when using it next time.
Also, dataformatstring = "{0: f}" is the default format. It displays two decimal places. If the number of decimal places to be displayed is another value, dataformatstring = "{0: fn.

<Asp: boundcolumn datafield = "time" headertext = "time" dataformatstring = "{0: yyyy/mm/dd}"> </ASP: boundcolumn>

 

 

Dataformatstring = "{0: Format String }"

{0} In dataformatstring represents the data itself, while the format string after the colon represents the format they want to display the data;

Number and currency format:
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
