Namespace: DevExpress.XtraReports

Assembly: DevExpress.XtraReports.v24.2.dll

NuGet Package: DevExpress.Reporting.Core

Declaration

C#

public static void ReplaceDataSource(
    XtraReport report,
    object oldDataSource,
    object newDataSource,
    bool includeSubReports = false
)

VB.NET

Public Shared Sub ReplaceDataSource(
    report As XtraReport,
    oldDataSource As Object,
    newDataSource As Object,
    includeSubReports As Boolean = False
)

Parameters

Name	Type	Description
report	XtraReport	A report instance.
oldDataSource	Object	The report’s data source.
newDataSource	Object	A new report data source.

Optional Parameters

Name	Type	Default	Description
includeSubReports	Boolean	False	true to replace data sources of subreports with the specified data source; otherwise, false.

Remarks

Consider the following specifics when you use the ReplaceDataSource method:

• If your new data source has the same type as the initial report data source, you can update settings of the initial data source. If types of the new and initial data sources are different, we recommend you create a new data source and call the ReplaceDataSource method to assign it to the report.
• Make sure that schemas of the new and initial report data sources match. Otherwise, bindings in your report might not work as expected, and therefore, report data can be displayed differently than in the report with the initial data source.

Example

The following code sample shows how to replace a report’s initial data source with a JSON data source:

C#

using DevExpress.XtraReports;
using DevExpress.DataAccess.Json;
//...

var report = new XtraReport1();

var jsonDataSource = new JsonDataSource {/* ... */};

DataSourceManager.ReplaceDataSource(report, report.DataSource, jsonDataSource);

VB.NET

Imports DevExpress.XtraReports
Imports DevExpress.DataAccess.Json
'...

Private report = New XtraReport1()

Private jsonDataSource = New JsonDataSource()

DataSourceManager.ReplaceDataSource(report, report.DataSource, jsonDataSource)
