XRSubreport.ParameterBindings Property
Provides access to the collection of subreport parameter bindings, which allow you to bind a subreport’s parameter value to a master report’s data field.
Namespace: DevExpress.XtraReports.UI
Assembly: DevExpress.XtraReports.v18.2.dll
Declaration
[SRCategory(ReportStringId.CatData)]
public ParameterBindingCollection ParameterBindings { get; }Property Value
| Type | Description |
|---|---|
| ParameterBindingCollection | A ParameterBindingCollection object, specifying the collection of subreport parameter bindings. |
Remarks
The parameter binding feature is useful when creating master-detail reports using subreports. You can bind a subreport’s parameter used as a filtering criterion to a master report’s data field, which will serve as a source of the parameter value. To do this, add a ParameterBinding object with the required settings to the ParameterBindings collection.
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 the sample Northwind database (nwind.mdb file is shipped with XtraReport installation). A detail report should use data from the Products table of the same database and contain an appropriate CatID parameter.

ParameterBinding parameterBinding = new ParameterBinding("CatID", null, "Categories.CategoryID");
