Blazor DataGrid Export Memory Stream

A production-ready sample demonstrating how to export Blazor DataGrid data as memory streams for PDF generation and advanced data handling. This project showcases both basic memory stream export and advanced scenarios like merging multiple PDFs.

Overview

This repository contains a complete Blazor application that demonstrates efficient data export patterns using the DataGrid component. Instead of writing directly to disk, the application exports grid data to in-memory streams, enabling flexible post-processing, dynamic content generation, and optimized performance for web-based scenarios.

Features

• Basic PDF Export: Export grid data directly as a PDF memory stream
• Advanced PDF Merging: Combine multiple grid exports with custom styling into a single PDF
• Custom Theme Support: Apply custom colors, fonts, and borders to exported PDFs
• Server-Side & Client-Side Rendering: Leverages Blazor's interactive capabilities
• Toolbar Integration: Export functionality integrated into the DataGrid toolbar
• Client-Side File Download: Seamless download experience using JavaScript interop

Prerequisites

• .NET SDK 8.0 or later
• Visual Studio 2022 or later
