C#
VB.NET

csharp

using DevExpress.DataAccess.Sql;
using DevExpress.XtraReports.UI;
using DevExpress.XtraReports;
//...

var report = new XtraReport1();

var dataBoundReports = DataSourceManager.GetDataSourceAssignables<XtraReport>(
    report: report,
    includeSubReports: true
);

foreach (var dataBoundReport in dataBoundReports) {
    (dataBoundReport.DataSource as SqlDataSource).ConnectionName = "nwind";
}

Imports DevExpress.DataAccess.Sql
Imports DevExpress.XtraReports.UI
Imports DevExpress.XtraReports
'...

Private report = New XtraReport1()

Private dataBoundReports = DataSourceManager.GetDataSourceAssignables(Of XtraReport)(report:= report, includeSubReports:= True)

For Each dataBoundReport In dataBoundReports
    TryCast(dataBoundReport.DataSource, SqlDataSource).ConnectionName = "nwind"
Next dataBoundReport
