Chemical Management Web Application
This project is a feature-rich, real-time chemical management web application designed for chemical suppliers to streamline the way they manage and access chemicals, products, and datasheets.
The application provides a centralized platform with an intuitive admin dashboard that allows for the creation, categorization, and management of chemical product data — all with a focus on usability, accessibility, and real-time reporting.
Key features include:
✅ Admin Panel
🔹 Secure, role-based access to a dedicated dashboard.
🔹 Allows admins to manage product information, update content, and generate reports.
✅ Define Categories
🔹 Admins can create and manage chemical categories (e.g., solvents, acids, bases, reagents).
🔹 Category management allows for easy filtering and organization of chemical records.
✅ Define Products
🔹 Products can be defined and linked to categories.
🔹 Each product can include attributes like chemical name, formula, concentration, storage conditions, safety data, etc.
🔹 Supports CRUD operations with data validation and integrity checks.
✅ Datasheet Reports
🔹 Generates detailed chemical datasheet reports for individual products or product groups.
🔹 Reports include technical data, safety instructions, hazard classifications, and handling guidelines.
✅ Dynamic PDF Generation
🔹 On-demand PDF generation of chemical datasheets reports.
🔹 Uses server-side PDF generation libraries to ensure accuracy and styling consistency.
🔹Built using iTextSharp, allowing dynamic rendering of HTML content into styled PDF format.
🔹 Allows users to download or print PDF documents directly from the interface.
✅ Architecture & Design Highlights
🔹Three-Tier Architecture (Presentation, Business Logic, Data Access Layer).
🔹Uses View-State for maintaining session-specific data in Web Forms.
🔹Implements SQL parameterized queries for secure data access.
Challenges
Accurate and Styled HTML-to-PDF Generation for Datasheets:
Creating PDFs that matched the on-screen HTML exactly — with complex layouts, styles, and special characters — was a significant challenge.
Solutions
iTextSharp with Custom HTML Templates:
🔹Adopted iTextSharp (a .NET wrapper for iText) to convert well-structured HTML into PDFs.
🔹Designed clean, print-optimized HTML templates with inline styles and table-based layouts for consistent rendering.
🔹Dynamically injected product data into templates using C# backend before PDF generation.
