FAQPage Schema
How do I build a QueryBuilder filter UI in ASP.NET Core?▼

A QueryBuilder filter UI in ASP.NET Core is built using Syncfusion EJ2 TagHelpers to define columns, rules, and nested groups. This generates a visual rule editor with AND/OR connectors, drag-and-drop reordering, and validation without wiring component behavior from scratch.

Can I export QueryBuilder rules as SQL or MongoDB queries in ASP.NET Core?▼

Yes, QueryBuilder rules can be exported as SQL, parameterized SQL, named SQL, or MongoDB queries in ASP.NET Core. The component supports importing and exporting filter logic as JSON, allowing integration with various database workflows and query execution pipelines.

Does the Syncfusion QueryBuilder work with grid integration and remote data sources?▼

Yes, the Syncfusion QueryBuilder supports grid integration, local data, and remote data sources in ASP.NET Core. You can bind the QueryBuilder to grids and remote endpoints, enabling real application workflows with dynamic filtering and data manipulation.

How do I manage nested groups and NOT conditions in ASP.NET Core QueryBuilder filtering?▼

Nested groups and NOT conditions in ASP.NET Core QueryBuilder filtering are managed through the component API for programmatic rule management. You can create complex rule hierarchies with AND/OR connectors, clone or lock rules, and apply NOT conditions for advanced logical grouping.

Do I need Syncfusion EJ2 TagHelpers to use the QueryBuilder for ASP.NET Core?▼

Yes, Syncfusion EJ2 TagHelpers are required for ASP.NET Core QueryBuilder implementation. The TagHelpers provide the necessary column and rule configuration, component API access for validation, templates, and programmatic rule management within ASP.NET Core applications.

Can I add localization and persistence to QueryBuilder filters in ASP.NET Core?▼

Yes, localization and persistence are supported for QueryBuilder filters in ASP.NET Core. You can configure custom templates and localization settings to support multiple languages, and persist filter rules across user sessions for consistent application workflows.
