Example

This example illustrates how to pass the value of a report parameter to a subreport placed in a another report.

To do this, create a ParameterBinding object and add it to the XRSubreport.ParameterBindings collection.

In this example, the main report is bound to the Categories table of thesample Northwind database. A detail report should use data from the Products table of the same database and contain an appropriate CatID parameter.

To learn how to solve this task without writing any code, see Creating a Master-Detail Report using Subreports.

C#

using DevExpress.XtraReports.UI;
// ...

private void XtraReport1_BeforePrint(object sender, System.ComponentModel.EventArgs e) {
    XtraReport report = sender as XtraReport;
    XRSubreport subreport = report.FindControl("xrsubreport1", true) as XRSubreport;
    ParameterBinding parameterBinding = new ParameterBinding("CatID", null, "Categories.CategoryID");
    subreport.ParameterBindings.Add(parameterBinding);
}

VB.NET

Imports DevExpress.XtraReports.UI
' ...

Private Sub XtraReport1_BeforePrint(sender As Object, e As System.ComponentModel.EventArgs)
    Dim report As XtraReport = TryCast(sender, XtraReport)
    Dim subreport As XRSubreport = TryCast(report.FindControl("xrsubreport1", True), XRSubreport)
    Dim parameterBinding As New ParameterBinding("CatID", Nothing, "Categories.CategoryID")
    subreport.ParameterBindings.Add(parameterBinding)
End Sub
