Assembly: DevExpress.Printing.v24.2.Core.dll
Declaration
Property Value
| Type | Description |
|---|---|
| XlNumberFormat | An XlNumberFormat object that specifies a cell number format. |
Remarks
The XlNumberFormat class provides a set of static properties you can use to specify the predefined Excel number format for a cell value. These properties allow you to display a numeric value in a cell as a number (XlNumberFormat.Number, XlNumberFormat.Number2, XlNumberFormat.NumberWithThousandSeparator, etc. ), percentage (XlNumberFormat.Percentage, XlNumberFormat.Percentage2), fraction (XlNumberFormat.Fraction, XlNumberFormat.Fraction2), date (XlNumberFormat.ShortDate, XlNumberFormat.LongDate, XlNumberFormat.MonthYear, etc.), time (XlNumberFormat.ShortTime12, XlNumberFormat.LongTime12, XlNumberFormat.MinuteSeconds, etc.), text (XlNumberFormat.Text) and so on.
If the predefined formats do not meet your demands, you can create a custom number format. To do this, assign the corresponding format string to the NumberFormat property of the XlCellFormatting object that defines common format settings for a cell. Note that the specified format string will be implicitly converted to the XlNumberFormat object.
To apply the specified number formatting options to a cell, pass the appropriate XlCellFormatting or XlNumberFormat object to the IXlCell.ApplyFormatting method as a parameter, or assign it to the IXlCell.Formatting property.
You can also use the XlFormatting.NetFormatString and XlFormatting.IsDateTimeFormatString properties of the XlCellFormatting object to specify the .NET numeric format for a cell value. For details on how to apply different number formats to worksheet cells, refer to the How to: Specify Number Format for Cell Content example.
