You can display another report inside the body of a main report using the Report Viewer. The following steps helps you to customize the subreport properties such as data source, report path, and parameters.
Add the sub report and main reports to your application Resources folder. In this tutorial, using the already created reports. Refer to the Create RDL Report section or Create RDLC Report section section for creating new reports.
Download the
side-by-side-main-report.rdl,side-by-side-sub-report.rdlreports from here. Also, you can add the report from Syncfusion installation location. For more information, see Samples and demos. The reports used from installed location, requiresNorthwindIO_Reports.sdfdatabase to run, so add it to your application.
Set the reportPath and reportServiceUrl properties of the Report Viewer as in following code snippet.
<script type="text/javascript">
$(function () {
$("#viewer").boldReportViewer({
reportServiceUrl: "/api/ReportViewer",
reportPath: '~/Resources/docs/side-by-side-main-report.rdl'
});
});
</script>
You can view the Web API service used in the above code from the Reporting Service git hub location. For more information, see Samples and demos.
Build and run the application. Preview and edit the result using the following.
<body style="overflow: hidden; position: static; margin: 0; padding: 0; height: 100%; width: 100%;">
<div id="viewer" style="position: absolute; height: 100%; width: 100%;"></div>
<script src="index.js"></script>
</body>$(function () {
$("#viewer").boldReportViewer({
reportServiceUrl: "https://demos.boldreports.com/services/api/ReportViewer",
reportPath: '~/Resources/docs/side-by-side-main-report.rdl'
});
});To change the subreport file path, set the ReportPath property of SubReportModel in the OnInitReportOptions method.
[NonAction]
public void OnInitReportOptions(ReportViewerOptions reportOption)
{
if (reportOption.SubReportModel != null)
{
reportOption.SubReportModel.ReportPath = System.Web.Hosting.HostingEnvironment.MapPath(@"~/Resources/docs/sub-report-detail.rdl");
}
}You can change the parameter default values of a subreport in the Web API Controller OnReportLoaded, method as given in the following code snippet.
[NonAction]
public void OnReportLoaded(ReportViewerOptions reportOption)
{
if (reportOption.SubReportModel != null)
{
reportOption.SubReportModel.Parameters = new BoldReports.Web.ReportParameterInfoCollection();
reportOption.SubReportModel.Parameters.Add(new BoldReports.Web.ReportParameterInfo()
{
Name = "SalesPersonID",
Values = new List<string>() { "2" }
});
}
}You can change the credential and connection information of the data sources used in the subreport using the SubReportModel in OnInitReportOptions method.
[NonAction]
public void OnInitReportOptions(ReportViewerOptions reportOption)
{
if (reportOption.SubReportModel != null)
{
reportOption.SubReportModel.DataSourceCredentials = new List<BoldReports.Web.DataSourceCredentials>();
reportOption.SubReportModel.DataSourceCredentials.Add(new BoldReports.Web.DataSourceCredentials("<database>", "Data Source=<instancename>;Initial Catalog=<database>;user id=<username>;password=<password>"));
}
}You can bind local business object data source collection only for RDLC reports. To specify data source of a RDLC subreport, set the ReportDataSource property in OnReportLoaded method.
The RDL report has the connection information in report definition itself, so no need to bind data source.
Add the RDLC sub report and main reports to your application Resources folder. You can downloaded it from here.
Set the reportPath and reportServiceUrl properties of the Report Viewer as in following code snippet.
<script type="text/javascript">
$(function () {
$("#viewer").boldReportViewer({
reportServiceUrl: "/api/SubreportDataSources",
processingMode: ej.ReportViewer.ProcessingMode.Local,
reportPath: '~/Resources/docs/product-list-main.rdlc'
});
});
</script>You can view the Web API service used in the above code from the Reporting Service git hub location. For more information, see Samples and demos.
Create a class and methods that returns business object data collection. Use the following code in your application Web API Service.
public class ProductList
{
public string ProductName { get; set; }
public string OrderId { get; set; }
public double Price { get; set; }
public string Category { get; set; }
public string Ingredients { get; set; }
public string ProductImage { get; set; }
public static IList GetData()
{
List<ProductList> datas = new List<ProductList>();
ProductList data = null;
data = new ProductList()
{
ProductName = "Baked Chicken and Cheese",
OrderId = "323B60",
Price = 55,
Category = "Non-Veg",
Ingredients = "grilled chicken, corn and olives.",
ProductImage = ""
};
datas.Add(data);
data = new ProductList()
{
ProductName = "Chicken Delite",
OrderId = "323B61",
Price = 100,
Category = "Non-Veg",
Ingredients = "cheese, chicken chunks, onions & pineapple chunks.",
ProductImage = ""
};
datas.Add(data);
data = new ProductList()
{
ProductName = "Chicken Tikka",
OrderId = "323B62",
Price = 64,
Category = "Non-Veg",
Ingredients = "onions, grilled chicken, chicken salami & tomatoes.",
ProductImage = ""
};
datas.Add(data);
return datas;
}
}Bind the business object data values collection to subreport by adding new item to the DataSources as in the following code snippet.
[NonAction]
public void OnReportLoaded(ReportViewerOptions reportOption)
{
//Assigning the data source for 'product-list.rdlc'
if (reportOption.SubReportModel != null)
{
reportOption.SubReportModel.DataSources = new BoldReports.Web.ReportDataSourceCollection();
reportOption.SubReportModel.DataSources.Add(new BoldReports.Web.ReportDataSource { Name = "list", Value = ProductList.GetData() });
}
}The data source name is case sensitive, it should be same as in the report definition.
To load subreport as stream, set the Stream property in OnInitReportOptions method.
[NonAction]
public void OnInitReportOptions(ReportViewerOptions reportOption)
{
if (reportOption.SubReportModel != null)
{
// Opens the report from application Resources folder using FileStream and loads the sub report stream.
FileStream reportStream = new FileStream(System.Web.Hosting.HostingEnvironment.MapPath(@"~/Resources/docs/product-list.rdlc"), FileMode.Open, FileAccess.Read);
reportOption.SubReportModel.Stream = reportStream;
}
}
[NonAction]
public void OnReportLoaded(ReportViewerOptions reportOption)
{
//Assigning the data source for 'Product List.rdlc'
if (reportOption.SubReportModel != null)
{
reportOption.SubReportModel.DataSources = new BoldReports.Web.ReportDataSourceCollection();
reportOption.SubReportModel.DataSources.Add(new BoldReports.Web.ReportDataSource { Name = "list", Value = ProductList.GetData() });
}
}
