Worksheet.Item[String] Property

Provides access to a cell range by its reference string.

Namespace: DevExpress.Spreadsheet

Assembly: DevExpress.Spreadsheet.v21.1.Core.dll


CellRange this[string reference] { get; }


Name Type Description
reference String

A String value that specifies the range reference in the A1 reference style or a defined name.

Property Value

Type Description

A CellRange object.


Use the Item method to access worksheet ranges by a cell reference or a defined name.


The Item property 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, use the IRangeProvider.Parse method.


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

// A range that includes cells from the top left cell (A1) to the bottom right cell (B5).
CellRange rangeA1B5 = worksheet["A1:B5"];

// A rectangular range that includes cells from the top left cell (C5) to the bottom right cell (E7).
CellRange rangeC5E7 = worksheet["C5:E7"];

// The C4:E7 cell range located in the "Sheet3" worksheet.
CellRange rangeSheet3C4E7 = workbook.Range["Sheet3!C4:E7"];

// A range that contains a single cell (E7).
CellRange rangeE7 = worksheet["E7"];

// A range that includes the entire column A.
CellRange rangeColumnA = worksheet["A:A"];

// A range that includes the entire row 5.
CellRange rangeRow5 = worksheet["5:5"];

// A minimal rectangular range that includes all listed cells: C6, D9 and E7.
CellRange rangeC6D9E7 = worksheet.Range.Parse("C6:D9:E7");

// A rectangular range whose left column index is 0, top row index is 0, 
// right column index is 3 and bottom row index is 2. This is the A1:D3 cell range.
CellRange rangeA1D3 = worksheet.Range.FromLTRB(0, 0, 3, 2);

// A range that includes the intersection of two ranges: C5:E10 and E9:G13. 
// This is the E9:E10 cell range.
CellRange rangeE9E10 = worksheet["C5:E10 E9:G13"];

// Create a defined name for the D20:G23 cell range.
worksheet.DefinedNames.Add("MyNamedRange", "Sheet1!$D$20:$G$23");
// Access a range by its defined name.
CellRange rangeD20G23 = worksheet["MyNamedRange"];
CellRange rangeA1D4 = worksheet["A1:D4"];
CellRange rangeD5E7 = worksheet["D5:E7"];
CellRange rangeRow11 = worksheet["11:11"];
CellRange rangeF7 = worksheet["F7"];

// Create a complex range using the Range.Union method.
CellRange complexRange1 = worksheet["A7:A9"].Union(rangeD5E7);

// Create a complex range using the IRangeProvider.Union method.
CellRange complexRange2 = worksheet.Range.Union(new CellRange[] { rangeRow11, rangeA1D4, rangeF7 });

// Fill the ranges with different colors.
complexRange1.FillColor = myColor1;
complexRange2.FillColor = myColor2;

// Use the Areas property to get access to a component of a complex range.
complexRange2.Areas[2].FillColor = Color.Beige;
