XtraReportBase.GetPreviousColumnValue(String) Method

Gets the previous value of the specified column in the report's XtraReportBase.DataSource.

Namespace: DevExpress.XtraReports.UI

Assembly: DevExpress.XtraReports.v19.2.dll

Declaration

public object GetPreviousColumnValue(
    string columnName
)
Public Function GetPreviousColumnValue(
    columnName As String
) As Object

Parameters

Name Type Description
columnName String

A String, which specifies the name of the column whose value to be obtained.

Returns

Type Description
Object

An object which represents 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, XtraReportBase.GetCurrentColumnValue and XtraReportBase.GetNextColumnValue methods to determine the value of the specified data column when creating a report, for example, in the XRControl.BeforePrint event handler.

To avoid casting the object returned by this method to an appropriate type, use the XtraReportBase.GetPreviousColumnValue<T> method, which returns a strongly typed object.
