NuGet Package: DevExpress.Spreadsheet.Core

Declaration

C#

CellRange FromLTRB(
    int leftColumnIndex,
    int topRowIndex,
    int rightColumnIndex,
    int bottomRowIndex
)

VB.NET

Function FromLTRB(
    leftColumnIndex As Integer,
    topRowIndex As Integer,
    rightColumnIndex As Integer,
    bottomRowIndex As Integer
) As CellRange

Parameters

Name	Type	Description
leftColumnIndex	Int32	An integer that is the zero-based index of the left column.
topRowIndex	Int32	An integer that is the zero-based index of the top row.
rightColumnIndex	Int32	An integer that is the zero-based index of the right column.
bottomRowIndex	Int32	An integer that is the zero-based index of the bottom row.

Returns

Type	Description
CellRange	A CellRange object.

Remarks

Get the IRangeProvider object via the Worksheet.Range property and use the FromLTRB method to access a cell range restricted by the specified rows and columns.

To access a cell range by its reference string, use the IRangeProvider.Item property or IRangeProvider.Parse method.

Example

The table below describes how to access a cell range in a worksheet.

Task	Use one of the following members
Access a cell range by its reference in the A1 style or name.	Worksheet.Item Workbook.Range.Item Worksheet.Range.Item Workbook.Range.Parse Worksheet.Range.Parse
Access a cell range by its reference in the R1C1 style.	Workbook.Range.Parse Worksheet.Range.Parse
Access a cell range by row and column indexes.	Workbook.Range.FromLTRB Worksheet.Range.FromLTRB
Create a union cell range.	CellRange.Union Workbook.Range.Union Worksheet.Range.Union
Access subranges of a union cell range.	CellRange.Areas
