IRangeProvider.Item[String] Property

Gets a cell range by its reference string.

Namespace: DevExpress.Spreadsheet

Assembly: DevExpress.Spreadsheet.v24.1.Core.dll

NuGet Package: DevExpress.Spreadsheet.Core

Declaration

C#

CellRange this[string reference] { get; }

VB.NET

ReadOnly Property Item(reference As String) As CellRange

Parameters

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

Property Value

Type	Description
CellRange	A CellRange object.

Remarks

Get the IRangeProvider object via the Worksheet.Range property and use the Item property to access a cell range object. Note that this 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.

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

// Create a complex range from multiple cell ranges separated by commas.
CellRange complexRange3 = worksheet["D15:F18, G19:H20, I21"];

// Fill the ranges with different colors.
complexRange1.FillColor = Color.LightBlue;

// Use the Areas property to get access to a complex range's component.
