1. Install NuGet Package

Install-Package Syncfusion.AspNetCore.QueryBuilder

2. Register Tag Helper

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

@addTagHelper *, Syncfusion.AspNetCore.QueryBuilder

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() {
