IRangeProvider.Parse(String) Method

Returns a cell range by its reference string in the A1 reference style.

Namespace: DevExpress.Spreadsheet

Assembly: DevExpress.Spreadsheet.v24.2.Core.dll

NuGet Package: DevExpress.Spreadsheet.Core

Declaration

C#

CellRange Parse(
    string reference
)

VB.NET

Function Parse(
    reference As String
) As CellRange

Parameters

Name	Type	Description
reference	String	A string that specifies the cell range reference in the A1 reference style.

Returns

Type	Description
CellRange	A CellRange object.

Exceptions

Type	Description
InvalidOperationException	Thrown if the specified reference is invalid.

Remarks

Get the IRangeProvider object via the Worksheet.Range property and use the Parse method to access a cell range object. The Parse method allows you to parse cell and table references, and defined names. Note that this method requires the cell range reference in the A1 reference style, regardless of which reference style is used in the workbook (DocumentSettings.R1C1ReferenceStyle). If you need to get a cell range by its R1C1 reference or by its reference in the style used in the workbook, pass the ReferenceStyle.R1C1 or ReferenceStyle.UseDocumentSettings value as the second parameter to the Parse method.

To get a cell range by the indexes of the bounding rows and columns, use the IRangeProvider.FromLTRB method.

Example

This example demonstrates how to access ranges of cells in a worksheet. There are several ways to accomplish this.

• The Worksheet.Item property obtains cell ranges defined by a cell reference (using A1 style) or a defined name.
• Ranges defined by a cell reference (using R1C1 or other reference styles), a defined name in a workbook, or by indexes of the bounding rows and columns - use the IRangeProvider.Item, IRangeProvider.Parse and IRangeProvider.FromLTRB members. Access the IRangeProvider object by the Worksheet.Range or IWorkbook.Range property.
