IXlTable.GetRowReference(String, String) Method

Returns a reference to the portion of the current row bounded by the specified columns.

Namespace: DevExpress.Export.Xl

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

Declaration

C#

XlTableReference GetRowReference(
    string firstColumnName,
    string lastColumnName
)

VB.NET

Function GetRowReference(
    firstColumnName As String,
    lastColumnName As String
) As XlTableReference

Parameters

Name	Type	Description
firstColumnName	String	A string that is the name of the column specifying the leftmost cell in the referenced row.
lastColumnName	String	A string that is the name of the column specifying the rightmost cell in the referenced row.

Returns

Type	Description
XlTableReference	An XlTableReference object that specifies the created reference.

Remarks

Use this method to create a reference to the cells in the same row as the formula, as the example below demonstrates. It creates a calculated column and uses a structured reference to specify the formula, which calculates yearly sales for each product in the table.
