This example shows how to add connect to data from the code.

First, you need to add the StinetCoreViewer component to the view page:

@using Stimulsoft.Report.Mvc;

...

@Html.StiNetCoreViewer(new StiNetCoreViewerOptions()
{
    Actions =
    {
        GetReport = "GetReport",
        ViewerEvent = "ViewerEvent"
    }
})

In the options above we define several actions, and we need to add it to the method.

The OnPostGetReport() action loads the report template and data, after thet it returns answer to the client part of the viewer using the GetReportResult() static method:

public IActionResult OnPostGetReport()
{
	// Loading the report template
	var reportPath = StiNetCoreHelper.MapPath(this, "Reports/TwoSimpleLists.mrt");
	var report = new StiReport();
	report.Load(reportPath);

	// Deleting connections in the report template
	report.Dictionary.Databases.Clear();

	// Loading data from the XML file
	var dataPath = StiNetCoreHelper.MapPath(this, "Reports/Data/Demo.xml");
	var data = new DataSet();
	data.ReadXml(dataPath);

	// Registering data in the report
	report.RegData(data);

	// Syncing the data structure, if required
	//report.Dictionary.Synchronize();

	return StiNetCoreViewer.GetReportResult(this, report);
}
