Assembly: Microsoft.ReportViewer.WinForms (in microsoft.reportviewer.winforms.dll)
Property Valuetrue if a report definition and all required parameters have been specified, and all data sources are ready for use; otherwise, false. The default is false.
In remote processing mode, all prompt data source credentials must be specified for this property to be true. In local processing mode, all required datasets must be loaded for this property to be true.
This property does not indicate that all information specified is valid, but only that the Report object has sufficient information to attempt to render the report. For example, it returns true if the prompt data source credentials have been specified but are not valid.
