Class PreviewBackend
- Namespace
- ReportWright.Blazor.Designer
- Assembly
- ReportWright.Blazor.Designer.dll
The viewer backend the preview tab runs on: the in-memory definition as it stands, with data invented from
the declared fields (ReportPreview) or the host's data through the designer backend's viewer. Export
is offered only for a saved, unchanged report, because the host exports what its store holds.

Methods
- CreateDataProviderAsync(string, ReportDefinition, IReadOnlyDictionary<string, ReportParameterValue>, CancellationToken)
Supplies the data for one run. In-process this is the live provider; over HTTP every dataset's rows are fetched here first, because the engine asks synchronously and a browser cannot answer that way.
- CreateSubreportResolver(string)
Resolves subreports for a run, or null when the host offers none.
- ExportAsync(string, ReportPageModel, IReadOnlyDictionary<string, ReportParameterValue>, string, CancellationToken)
Exports a run.
- LoadDefinitionAsync(string, CancellationToken)
Loads a report definition.
