Document Viewer for Blazor Server
Report Designer for Blazor Server
Quick Start
The most straightforward and easiest method to create a sample Blazor WebAssembly reporting app is to start with the DevExpress Blazor template, as described in the following topic: Get Started with Blazor Reporting.
Open a Report
Use the following properties and methods to specify a report to open:
| Document Viewer | Report Designer |
|---|---|
| DxDocumentViewer.ReportName | DxReportDesigner.ReportName |
| DxDocumentViewer.OpenReport(System.String) | DxReportDesigner.OpenReport(System.String) |
You should implement and register a report name resolution service to parse a report name and return a report instance.
If you followed the steps in the Integrate Blazor Server Reporting (JavaScript-Based) Controls in DevExpress Blazor Application topic, your application already contains a report name resolution service. A report storage (a ReportStorageWebExtension class descendant) resolves a report name to a report instance.
If your application contains only the Document Viewer control, you can implement and register the IReportProvider service to get a report instance by name.
Click Print in the Toolbar to print the entire document or click Print Page to print the active document page.
The Document Viewer renders the report in PDF and opens a new browser tab (page) to print the PDF file. If the PDF plugin is installed in your browser, the Print dialog is invoked. If the PDF plugin is unavailable, the Document Viewer exports the report document to a PDF file and offers to download this file instead of printing.
You can set the DxDocumentViewerExportSettings.UseSameTab property to true to print the document in the same tab. The ShowPrintNotificationDialog property allows you to show or hide an additional dialog with a link to the PDF file that was just sent to the printer:
Export
Click Export To and select an export format from the list to download the report in the selected format.
The browser opens a new tab (page) to export a document. You can set the DxDocumentViewerExportSettings.UseSameTab property to true to export the document in the same tab.
Click Export Options to invoke the Export Options Panel and specify format-specific options.
Bind to Data
Add the data source to the DxReportDesigner.DataSources collection to make the data source available to the Report Designer.
