Getting Started

This section briefly explains about how to include a simple Query Builder in your ASP.NET MVC application. You can refer ASP.NET MVC Getting Started documentation page for introduction part of the system requirements and configure the common specifications.

Add Query Builder to the project

We are going to render Query Builder component in Index.cshtml page.

razor
default.cs
@Html.EJS().QueryBuilder("querybuilder").Width("72%").Columns(col =>
   {
       col.Field("EmployeeID").Label("Employee ID").Type("number").Add();
       col.Field("FirstName").Label("First Name").Type("string").Add();
       col.Field("TitleOfCourtesy").Label("Title Of Courtesy").Type("boolean").Values(new List<string> { "Mr.", "Mrs." }).Add();
       col.Field("Title").Label("Title").Type("string").Add();
       col.Field("HireDate").Label("Hire Date").Type("date").Format("dd/MM/yyyy").Add();
       col.Field("Country").Label("Country").Type("string").Add();
