Implementing Pivot Table (ASP.NET Core)

Syncfusion ASP.NET Core Pivot Table (PivotView) enables multi-dimensional data visualization and analysis with interactive row/column/value axes, real-time aggregation, flexible filtering, and comprehensive export options.

⚠️ Important: Always verify API class names, properties, and method signatures by consulting the reference files in this skill (references/*.md). These are maintained with verified, working examples. Do not assume API details from other sources.

⚠️ Security Warning: Data Source Validation

CRITICAL SECURITY NOTICE: When implementing pivot tables, always use trusted data sources. Never fetch or bind data from untrusted or user-provided URLs without proper validation and sanitization.

Security Best Practices:

1. Use Local Data: Prefer local, in-memory data sources for maximum security
2. Validate Remote Sources: Only connect to authenticated and authorized API endpoints under your control
3. Sanitize User Input: Never allow users to specify arbitrary URLs or data sources
4. Use Configuration: Store connection strings and API URLs in secure configuration (appsettings.json with IConfiguration)
5. Implement Authentication: Require authentication for all database and API connections
6. Apply Authorization: Use [Authorize] attributes and role-based access control

Security Risks:

• Indirect Prompt Injection: Untrusted third-party data can contain malicious content that manipulates AI agent behavior
• Data Exposure: Unvalidated remote connections may expose sensitive information
• SQL Injection: Unsanitized database queries can lead to data breaches
• XSS Attacks: Unescaped data rendered in the UI can execute malicious scripts

✅ Safe: Local data, authenticated APIs under your control, parameterized SQL queries ❌ Unsafe: User-provided URLs, unauthenticated endpoints, hardcoded connection strings

When to Use This Skill

Use this skill when building an ASP.NET Core application and the user needs:

• Pivot reporting with row, column, value, and filter axes
• Data aggregation with 20+ summary types (Sum, Avg, Count, Percentage, RunningTotals, etc.)
• Interactive report building via field list and grouping bar UI
• Data source binding (local JSON/CSV, SQL Server, OLAP, relational databases)
• Filtering (member, label, value filtering with search/sort)
• Sorting (field sorting, custom order, value sorting)
• Advanced features (drill-down/up, drill-through, calculated fields, pivot chart)
• Formatting (conditional formatting, number formatting, custom styling)
• Export (Excel, PDF, CSV, print)
• Performance optimization (virtual scrolling, paging, data compression)
