This example shows how to use a User Data object. First, load scripts:

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

Next, add report viewer:

<!--Report Viewer-->
<StiBlazorViewer Report="@Report" />

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

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

	protected override async Task OnInitializedAsync()
	{
await base.OnInitializedAsync();
		
		//Create report object and load template
		this.Report = new StiReport();
		var reportBytes = await Http.GetByteArrayAsync("Reports/UserData.mrt");
		this.Report.Load(reportBytes);

...

Next, create user data and register it in the report template:

...

		//Create user data
		var stiUserData1 = new Stimulsoft.Report.Dictionary.StiUserData();
		stiUserData1.Columns.AddRange(new Stimulsoft.Report.Dictionary.StiDataColumn[] {
			new Stimulsoft.Report.Dictionary.StiDataColumn("Name", "Name", "Name", typeof(string), null),
			new Stimulsoft.Report.Dictionary.StiDataColumn("Value", "Value", "Value", typeof(string), null)});
		stiUserData1.Count = 5;
		stiUserData1.GetData += new Stimulsoft.Report.Dictionary.StiUserGetDataEventHandler(stiUserData1_GetData);

		//Register new data in the report template
		this.Report.RegData("UserData", stiUserData1);
	}
	
...

Finally, use user data arrays:

...

	//User data arrays
    private string[] nameArray = new string[] { "Mahesh Chand", "Mike Gold", "Raj Beniwal", "Praveen Kumar", "Dinesh Beniwal" };
    private string[] valueArray = new string[] { "00", "01", "02", "03", "04" };

    private void stiUserData1_GetData(object sender, Stimulsoft.Report.Dictionary.StiUserGetDataEventArgs e)
    {
        if (e.ColumnName == "Name") e.Data = nameArray[e.Position];
        if (e.ColumnName == "Value") e.Data = valueArray[e.Position];
    }
}
