Overview

The ASP.NET Core Blazor Query Builder is used for filtering large amounts of data by creating or editing conditions that can be combined with data visualization controls like DataGrid and Charts to view the filtered data. It outputs structured JSON of filters that can be easily parsed to create SQL queries. It allows you to create conditions and group them using AND/OR logic.


Data Binding

Query Builder UI can be bound to data from a variety of data sources in the form of a JavaScript object array collection. It auto-populates the data source and maps the data to the appropriate fields.

Integration with Data Manager

Integrating the Data Manager control with the Query Builder simplifies communication with a data source and returns the desired result based on the provided filters.


Templates

Templates are used to create a custom user experience. Query Builder provides template support to integrate with other input components such as Dropdown List, AutoComplete , Checkbox, Slider, and others.


Summary View

Query Builder UI supports a summary view that outputs the filter query in SQL format.

Import and export

Supports importing and exporting Query Builder data to and from structured JSON and SQL formats.


Touch-friendly and Responsive

Query Builder UI provides responsive mode that gives adaptive redesigned UI appearance for mobile devices and best user experience on all phones, tablets, and desktop form factors.
