In this article I will explain with an example, how to bind DataTable (DataSet) to WebGrid in ASP.Net Core Razor Pages.
The DataTable (DataSet) will be populated from Database Table using ADO.Net and then, used for populating WebGrid in ASP.Net Core Razor Pages.
 
 
MVC6 Grid for ASP.Net Core
This article makes use of MVC6 Grid library for implementing WebGrid, as it is not available by default in .Net Core.
For more details on how to use MVC6 Grid, please refer the article Using MVC6 Grid in ASP.Net Core Razor Pages.
 
 
Database
Here I am making use of Microsoft’s Northwind Database. You can download it from here.
Download and install Northwind Database
 
 
Namespaces
You will need to import the following namespaces.
using System.Data;
using System.Data.SqlClient;
 
 
Razor PageModel (Code-Behind)
The PageModel consists of following Handler method.
Handler method for handling GET operation
Inside this Handler method, the Top 10 records are fetched from the Customers Table using ADO.Net.
The records are inserted into a public property Customers (DataSet) using SqlDataAdapter class object.
Finally, the Customers is returned to the Razor Page.
public class IndexModel : PageModel
{
    public DataSet Customers { get; set; }
 
    public void OnGet()
    {
        string constr = @"Data Source=.\SQL2019;Initial Catalog=Northwind;Integrated Security=true";
        using (SqlConnection con = new SqlConnection(constr))
        {
            string query = "SELECT TOP 10 CustomerID, ContactName, City, Country FROM Customers";
            using (SqlCommand cmd = new SqlCommand(query, con))
            {
                using (SqlDataAdapter sda = new SqlDataAdapter(cmd))
                {
                    using (DataSet ds = new DataSet())
                    {
                        Customers = new DataSet();
                        sda.Fill(Customers);
                    }
                }
            }
        }
    }
}
 
 
Razor Page (HTML)
Inside the Razor Page, the System.Data, NonFactors.Mvc.Grid namespaces and mvc-grid.css file are inherited.
The DataTable is passed to the Grid function of the MVC6 Grid HTML Helper class.
The columns have been added using the Build method of the MVC6 Grid HTML Helper class.
Inside the Build method of the MVC6 Grid HTML Helper class, a foreach loop will be executed over the Columns.
Inside the loop, dynamically columns have been added using the Add method and the Header Text of the column is set using the Titled function by passing the Column Name.
@page
@model WebGrid_DataTable_DataSet_MVC_Core.Pages.IndexModel
@using System.Data;
@using NonFactors.Mvc.Grid;
 
@{
    Layout = null;
}

    @(Html.Grid(Model.Customers.Tables[0].Rows.Cast<DataRow>())
        .Build(columns =>
        {
            foreach (DataColumn column in Model.Customers.Tables[0].Columns)
            {
                columns.Add(model => model[column.ColumnName]).Titled(column.ColumnName);
            }
        })
    )
</body>
</html>
