GridView RowDataBoundEvent not running

I'm working with a GridView and I am using a TableAdapter to communicate with my SQL Server 2017 Express. I have managed to display the table into a GridView but I would like to make the name of each entry in my database have a hyperlink that will direct the user to another page that contains a DetailsView that would allow the user to edit the corresponding entry. However, I am currently have troubles with the RowDataBoundEvent as it seemingly is not triggering.

When I set a breakpoint right at the if statement, the program does not stop at the breakpoint. 

protected void ProductViewRowBound(object sender, GridViewRowEventArgs e)
{
    if(e.Row.RowType == DataControlRowType.DataRow)
    {
        string hyperLink = e.Row.Cells[1].Text;
        e.Row.Cells[1].Text = "Test";
        //HyperLink link = new HyperLink;
    }
}

I checked my RowDataBound method name and it matches the one I specified in the aspx file:

<asp:GridView ID="ProductView" runat="server" Height="299px" Width="578px" AllowPaging="True" HorizontalAlign="Center"
    OnRowDataBoundEvent="ProductViewRowBound" style="table-layout:auto">
    <HeaderStyle Width="300px" />
</asp:GridView>

CS File:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;


public partial class Maintenance : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            DataTable dt = new DataTable();
            ProductSetTableAdapters.Product_Table_AlphaTableAdapter productAdapter = new ProductSetTableAdapters.Product_Table_AlphaTableAdapter();
            ProductView.DataSource = productAdapter.GetData();
            ProductView.DataBind();
        }

        ProductView.RowDataBound += new GridViewRowEventHandler(ProductViewRowBound);
    }

    protected void ProductViewRowBound(object sender, GridViewRowEventArgs e)
    {
        if(e.Row.RowType == DataControlRowType.DataRow)
        {
            string hyperLink = e.Row.Cells[1].Text;
            e.Row.Cells[1].Text = "Test";
            //HyperLink link = new HyperLink;
        }
    }
}

ASPX File:

<%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Maintenance.aspx.cs" Inherits="Maintenance" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
    <div style="overflow-x:scroll;overflow-y:scroll; margin-left:auto; margin-right:auto;">
        <asp:GridView ID="ProductView" runat="server" Height="299px" Width="578px" AllowPaging="True" HorizontalAlign="Center"
            OnRowDataBoundEvent="ProductViewRowBound" style="table-layout:auto">
            <HeaderStyle Width="300px" />
        </asp:GridView>
    </div>

</asp:Content>

Why is my RowDataBoundEvent not running and what can I do to fix it?

First, OnRowDataBoundEvent does not exist. It should be OnRowDataBound in the GridView.

<asp:GridView ID="ProductView" runat="server" OnRowDataBound="ProductViewRowBound">

Next you are binding the correct method to the GridView from code behind, but AFTER you bind data to the GridView. So it will not work when you bind productAdapter.GetData().

So either set the correct event name in the GridView aspx or move the method binding above ProductView.DataBind();
