Report variables receive values from the Blazor UI; assign them by name on a copy of the report, then re-render.

Set a variable and re-render.
var report = Report.Clone() as StiReport;

report["MySuperUselessVariable"] = NewValueInput;
report.Render();

Report = report;

How it works. The value entered in the input box is bound into the report before rendering, so the viewer immediately shows the updated result.
