Overview

The ASP.NET Core Query Builder is a rich and responsive UI 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 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

ASP.NET Core Query Builder 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

ASP.NET Core Query Builder 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

ASP.NET Core Query Builder provides a responsive mode that gives an adaptive, redesigned UI appearance for mobile devices and a great user experience on all phone, tablet, and desktop form factors.

Touch-friendly and adaptive mobile user interface


Themes

The ASP.NET Core Query Builder supports several built-in themes such as material, bootstrap, fabric (office 365), and high contrast. The users can customize any one of these built-in themes or create new themes to achieve their own desired look and feel either by simply overriding SASS variables or using our Theme Studio application with ease.

We do not sell the ASP.NET Core Query Builder separately. It is only available for purchase as part of the Syncfusion ASP.NET Core suite, which contains over 70+ ASP.NET Core components, including the Query Builder UI. A single developer license for the Syncfusion Essential Studio for ASP.NET Core suite costs $995.00 USD, including one year of support and updates. On top of this, we might be able to offer additional discounts based on currently active promotions. Please contact our sales team today to see if you qualify for any additional discounts.

You can find our ASP.NET Core Query Builder demo here.

No, our 70+ ASP.NET Core components, including Query Builder UI, are not sold individually, only as a single package. However, we have competitively priced the product so it only costs a little bit more than what some other vendors charge for their Query Builder UI alone. We have also found that, in our experience, our customers usually start off using one of our products and then expand to several products quickly, so we felt it was best to offer all 70+ ASP.NET Core components for a flat fee of $995/developer. On top of this, we might be able to offer additional discounts based on currently active promotions. Please contact our sales team today to see if you qualify for any additional discounts.

No, this is a commercial product and requires a paid license. However, a free community license is also available for companies and individuals whose organizations have less than $1 million USD in annual gross revenue and five or fewer developers.

A good place to start would be our comprehensive getting started documentation.
