BackgroundWorker, subscribing to the engine's progress event:private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
report.Load(stream);
report.IsRendered = false;
report.Compile();
report.CompiledReport.Rendering += CompiledReport_Rendering;
report.Render(false);
}
private void CompiledReport_Rendering(object sender, EventArgs e)
{
button1.Invoke((EventHandler)delegate { button1.Text = report.StatusString; });
}Compile()+Render(false)— compile once, then render without showing progress UI on the worker thread.CompiledReport.Renderingevent — fires as pages build; marshalreport.StatusStringback to the UI withInvoke.
