XlCellFormatting.FromNetFormat(String, Boolean) Method
Specifies a number format for cell values based on the given .NET-style format string.
Namespace: DevExpress.Export.Xl
Assembly: DevExpress.Printing.v23.2.Core.dll
NuGet Package: DevExpress.Printing.Core
Declaration
public static XlCellFormatting FromNetFormat(
string formatString,
bool isDateTimeFormat
)Parameters
| Name | Type | Description |
|---|---|---|
| formatString | String | A String value that represents the format pattern. |
| isDateTimeFormat | Boolean | true, if the formatString parameter is a date and time format specifier; otherwise, false. |
Returns
| Type | Description |
|---|---|
| XlCellFormatting | An XlCellFormatting object that specifies the number format options to be applied to a cell. |
Remarks
Use the FromNetFormat method to specify the .NET numeric format for a cell value. You can also use the XlFormatting.NetFormatString and XlFormatting.IsDateTimeFormatString properties of the XlCellFormatting object to define and control the number formatting options. The XlCellFormatting.FromNetFormat method automatically sets these properties according to the values of its parameters.
To apply number formatting options to a cell, pass the XlCellFormatting object to the IXlCell.ApplyFormatting method as a parameter, or assign it to the IXlCell.Formatting property.
Note that the specified .NET number format will be implicitly converted to the native Excel format. To directly specify the native Excel number format for a numeric value in a cell, use the XlFormatting.NumberFormat property. For details on how to apply different number formats to worksheet cells, refer to the How to: Specify Number Format for Cell Content example.
