Assembly: DevExpress.XtraReports.v23.2.dll

NuGet Package: DevExpress.Reporting.Core

Declaration

C#

public object GetPreviousColumnValue(
    string columnName
)

VB.NET

Public Function GetPreviousColumnValue(
    columnName As String
) As Object

Parameters

Name	Type	Description
columnName	String	A String that is the name of the column whose value you want to retrieve.

Returns

Type	Description
Object	An object that is the previous value of the specified column in the data source. If the specified column was not found, this method returns null (Nothing in Visual Basic).

Remarks

Use the GetPreviousColumnValue method to retrieve the value of the specified data column. You can call this method in the XRControl.BeforePrint event handler.

You can use the XtraReportBase.GetPreviousColumnValue<T>(String) method, which returns a strongly typed object, to eliminate the need to cast the returned object to the appropriate type.

When the current row is the first row (CurrentRowIndex == 0), this method returns the value of the first record.
