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.
Bind data seamlessly with various local and remote data sources such as JSON, OData, WCF, and RESTful web services with the help of a data manager.
You can import or export filter from or to the Query Builder in structured formats like JSON and SQL.
Query Builder has a highly responsive layout and an optimized design for desktops, touchscreens, and smartphones. It works well on all mobile phones that use iOS, Android, or Windows OS.
You can add checkboxes, sliders, and dropdown lists to the Query Builder using three different templates options.
Cutting-edge design with several built-in themes, such as Fluent, Tailwind CSS, Bootstrap, Material, and Fabric. Utilize the online Theme Studio tool to customize themes easily.
Enables users from different locales to use the component by formatting strings to suit preferences.
Easily get started with ASP.NET Core Query Builder using a few simple lines of C# code, as demonstrated below. Also, explore our ASP.NET Core Query Builder Example that shows you how to render and configure the ASP.NET Core Query Builder Component.

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.
Add controls like Checkbox, Slider, and Dropdown List to customize the ASP.NET Core Query Builder using templates.
Users can define their own widgets to customize the elements such as and/or/not connectors and add rules/groups buttons using the header template.
Users can define their own widgets to customize the entire column elements such as fields, operators, and values using the rule template.
Users can define their own widgets to customize the elements for values using the value template.
Model binding binds properties for the components used in field, operator, and value columns. To implement model binding, assign fieldModel, operatorModel, and valueModel properties in the Query Builder.
The ASP.NET Core Query Builder supports a summary view that outputs the filter query in SQL format.
Complex data binding allows users to create subfields within the main fields. This can be useful for representing hierarchical or multilevel data in a more organized and structured way. To create subfields, users can either specify the complex data in nested columns or specify a complex data source and separator.
The column definitions are used as the data source schema in the Query Builder UI. This plays a vital role in rendering column values. The query builder operations, such as create or delete conditions and create or delete groups, are based on column definitions.
Users can create a filter by adding or deleting conditions or groups. Users can get a created filter as SQL query, JSON, and data manager predicates.
Change the look and feel of the ASP.NET Core Query Builder UI by customizing its default appearance and style using HTML or CSS.
Ensure data integrity by locking groups or rules to prevent unintended interactions. Use the lockRule and lockGroup methods for this purpose.
Effortlessly create duplicates of rules or groups within the Query Builder with the clone support feature. This creates an exact replica next to the original using the cloneRule and cloneGroup methods.
Users can reposition rules or groups within the component by just dragging and dropping them. This provides an intuitive, flexible way to construct and modify queries.
Users can integrate standalone connectors between rules or groups within the same group. This allows for greater flexibility, as users can connect rules or groups using different connectors, enhancing the complexity and precision of query construction.
Query Builder is also available in Blazor, Angular, React, Vue, and JavaScript frameworks. Check out the different Query Builder platforms from the links below,
The ASP.NET Core Query Builder works well with all modern web browsers such as Chrome, Firefox, Microsoft Edge, Safari, and Opera.
We do not sell the ASP.NET Core Query Builder separately. It is only available for purchase as part of the Syncfusion team license. This contains over 1,800 components and frameworks, including the ASP.NET Core Query Builder. The price of the team license starts at $395 per month for 5 developers, and includes support and updates until the subscription expires. In addition, we might offer discounts based on currently active promotions. Please contact our product specialists today to see if you qualify for any additional discounts.
You can find our ASP.NET Core Query Builder demo, which demonstrates how to render and configure the Query Builder.
No, our 1,800+ components and frameworks for web, mobile, and desktop, including our ASP.NET Core Query Builder, are not sold individually. They are only available as part of a team license. 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 control 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 1,800+ components and frameworks for a subscription fee that starts at $395 per month for a team of 5 developers. Additionally, we might be able to offer discounts based on currently active promotions. Please contact our product specialists 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, 5 or fewer developers, and 10 or fewer total employees.
A good place to start would be our comprehensive getting started documentation.
