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, I checked the msdn for half a day and found that Dataformatstring Yes, this function can be implemented, but how to set it does not work. Finally, we found that because 2.0 is for security consideration, we also need to set it at the same time. Htmlencode = false to make dataformatstring take effect . Leave a mark. You don't need to waste more time when using it next time. And, Dataformatstring = "{0: f}", which is the default format and displays two decimal places If the number of decimal places to be displayed is another value, Dataformatstring = "{0: fn }" You can. Example: <Columns>
<Asp: boundfield datafield = "employeeid"/>
<Asp: boundfield datafield = "lastname"/>
<Asp: boundfield datafield = "birthdate" Htmlencode = "false" Dataformatstring = "{0: yyyy-mm-dd}"/>
</Columns>

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:

"{0: c}" 12345.6789 $12,345.68
"{0: c}"-12345.6789 ($12,345.68)

"{0: E10 }" 12345.6789 1.2345678900e + 004
"{0: F }" 12345.6789 12345.68
