Introduction to RDLC
RDLC stands for Report Definition Language Client-side. It is a file format used to create professional reports in .NET applications. Think of it as a document template that can show data in a structured way.
Simple Explanation
RDLC is like a Word document template. You design how the report looks (headers, tables, charts), and then you fill it with data from your database.
Features of RDLC
- Professional Layout: Design reports that look like official documents
- Charts and Graphs: Visualize data with bar charts, pie charts, and line graphs
- Grouping and Aggregation: Group data by categories and show totals (sum, average, count)
- Export Options: Save reports as PDF, Excel, or Word files
- Printing: Print reports directly from your application
- Parameterized Reports: Ask the user for input (like a date range) before showing the report
- Subreports: Embed one report inside another
RDLC vs RDL

|---|---|---|
| Where it runs | On your computer (client-side) | On a server (server-side) |
| Processing | Local Processing (your app handles it) | Server Processing (SQL Server handles it) |
