This example shows how to use business objects in the report. First, load scripts:

@using Stimulsoft.Base
@using Stimulsoft.Report
@using Stimulsoft.Report.Blazor
@using Stimulsoft.Report.Web

Next, add report designer:

<StiBlazorDesigner Report="@Report" OnSaveReport="@OnSaveReport" />

After that, create empty report object and load report template:

@code
{
	//Report object to use in designer
	private StiReport Report;

	protected override async Task OnInitializedAsync()
	{
		await base.OnInitializedAsync();

		//Create empty report object
		this.Report = new StiReport();

		//Load report template
		var reportBytes = await Http.GetByteArrayAsync("Reports/BusinessObjects.mrt");
		this.Report.Load(reportBytes);

...

Then, create and register business object:

...

		//Create business object
		var list = GetBusinessObject();

		//Register business object in the report template
		this.Report.RegBusinessObject("MyList", list);
		this.Report.Dictionary.Synchronize();
	}

...

Next, create save method:

...

    private void OnSaveReport(StiSaveReportEventArgs args)
    {
  		var reportJson = args.Report.SaveToJsonString();
		
		await Task.CompletedTask;
    }


...

Finally, fill data to business objects:

...

	//Business objects
    public class BusinessEntity
    {
        public string Name { get; set; }

        public string Alias { get; set; }

        public BusinessEntity(string name, string alias)
        {
            Name = name;
            Alias = alias;
        }
    }

    private System.Collections.ArrayList GetBusinessObject()
    {
        var list = new System.Collections.ArrayList();
        list.Add(new BusinessEntity("name1", "alias1"));
        list.Add(new BusinessEntity("name2", "alias2"));
        list.Add(new BusinessEntity("name3", "alias3"));

        return list;
    }
}
