Blazor Pivot Table Example - External Filter Integration Support

This sample demonstrates applying external date range filters to Pivot Table data source for enhanced performance with large datasets.

Date filtering features:

• Users select start and end dates via date pickers
• Table updates to show records within selected range
• Pre-filters data at runtime using custom function
• Improves performance by avoiding in-component filtering

The external filtering method:

• Compares selected date range with record dates
• Reduces processing load on Pivot Table
• Results in more responsive user experience

Note: Aggregation is performed only on filtered data. Records outside selected range are excluded from calculations.
