属性

注解

DataTextFormatString使用属性可为列表控件中的项提供自定义的显示格式。Use the DataTextFormatString property to provide a custom display format the items in a list control.

数据格式字符串由以冒号分隔的两部分组成,格式为 { ABxx }。The data format string consists of two parts, separated by a colon, in the form { A : Bxx }. 例如,格式化字符串{0:F2}将设置单元格的格式,以显示具有两个小数位的固定的点号。For example, the formatting string {0:F2} would format the cell to display a fixed point number with two decimal places.

备注

整个字符串必须括在大括号中,以指示它是格式字符串而不是文本字符串。The entire string must be enclosed in braces to indicate that it is a format string and not a literal string. 大括号外的任何文本都显示为文本。Any text outside the braces is displayed as literal text.

冒号前面的值(A在常规示例中)指定从零开始的参数列表中的参数索引。The value before the colon (A in the general example) specifies the parameter index in a zero-based list of parameters.

备注

此值只能设置为0,因为每个单元格中只有一个值。This value can only be set to 0 because there is only one value in each cell.

冒号后面的字符(B在常规示例中)指定在中显示值的格式。The character after the colon (B in the general example) specifies the format to display the value in. 下表列出了常见格式。The following table lists the common formats.
