Syncfusion ASP.NET Core QueryBuilder Component

A UI component for building complex SQL-like queries through an intuitive rule editor. Ideal for filter builders, report configurators, and search interfaces without requiring manual query syntax entry.

Using this package with an AI coding agent

Before generating Syncfusion code, ask your AI coding agent to run the Syncfusion setup using the following prompt:

Set up this project for Syncfusion before generating code. Fetch and follow the official instructions at https://ai.syncfusion.com, then report the detected platform, installed skill pack, MCP status, and any required licensing action.

The setup detects your project's platform and loads the appropriate Syncfusion skill pack. No Syncfusion account or MCP key is required to install or read Syncfusion agent skills.

Platform reference: https://ai.syncfusion.com/aspnet-core/llms.txt

Key Features

  • Visual condition builder with groups and rules
  • Supports all common operators: equal, not equal, contains, starts with, between, etc.
  • Generates SQL, MongoDB, and JSON query outputs
  • Import existing query rules back into the UI
  • Custom templates for rule value inputs
  • Integration with DataGrid and other data components
  • Accessibility and keyboard navigation

Common Setup

All Syncfusion ASP.NET Core controls share the same foundational setup steps:

1. Install NuGet Package

Install the QueryBuilder package and the themes package, which provides the stylesheets referenced below:

dotnet add package Syncfusion.AspNetCore.QueryBuilder
dotnet add package Syncfusion.AspNetCore.Themes

2. Register Tag Helper

Add the following to ~/Pages/_ViewImports.cshtml or ~/Views/_ViewImports.cshtml:

@addTagHelper *, Syncfusion.AspNetCore.Base
@addTagHelper *, Syncfusion.AspNetCore.QueryBuilder

3. Add Stylesheet & Script References

In your layout file (~/Pages/Shared/_Layout.cshtml):

<head>
    
    <link rel="stylesheet" href="_content/Syncfusion.AspNetCore.Themes/styles/fluent2.css" />
    
    
    <script src="_content/Syncfusion.AspNetCore.QueryBuilder/scripts/sf-query-builder.min.js"></script>
</head>

4. Register Script Manager

In your layout file (~/Pages/Shared/_Layout.cshtml), At the end of your <body> tag:

<ejs-scripts></ejs-scripts>

Quick Start

Step 1: Create a PageModel

Create ~/Pages/Index.cshtml.cs:

using Microsoft.AspNetCore.Mvc.RazorPages;
using System.Collections.Generic;

public class IndexModel : PageModel
{
    public List<FilterField> Fields { get; set; } = new List<FilterField>
    {
        new FilterField { Text = "Age", Value = "Age", Type = "number" },
        new FilterField { Text = "Status", Value = "Status", Type = "string" },
        new FilterField { Text = "Department", Value = "Department", Type = "string" }
    };

    public void OnGet()
    {
        // Initialize query builder
    }
}

public class FilterField
{
    public string Text { get; set; }
    public string Value { get; set; }
    public string Type { get; set; }
}

Step 2: Create the View

Create ~/Pages/Index.cshtml:

@page
@model IndexModel

<div class="container mt-5">
    <h2>Query Builder Demo</h2>

    <ejs-querybuilder id="querybuilder" rule="@(new Rule { condition = "and", rules = new List<Rule>() })" columns="@Model.Fields">
    </ejs-querybuilder>

    <div class="mt-3">
        <button class="btn btn-primary" onclick="getQuery()">Get Query</button>
    </div>
</div>

<script>
function getQuery() {
    const querybuilder = document.getElementById('querybuilder').ej2_instances[0];
    const query = querybuilder.getRule();
    console.log(JSON.stringify(query));
}
</script>
