Quick practical summary and fixes that extend the replies from , , , and .

For an HTML report shown inside your Windows app the simplest approach is to host the page in a WebBrowser control and let the page’s JavaScript handle the click. That keeps DOM logic in the HTML (easy to inspect and debug) while the app can call into the page or the page can call back into the app when needed. (learn.microsoft.com)

Example: use event delegation so every table button doesn’t need its own inline handler (works when rows are generated dynamically):

document.addEventListener('click', function(e) {
  if (!e.target.matches('button.row-btn')) return;
  var tr = e.target.closest('tr');
  var firstCell = tr && tr.querySelector('td');
  var id = firstCell ? firstCell.textContent.trim() : null;
  // now use id (send to server, call window.external, etc.)
});

If the host app needs to call JavaScript functions, use HtmlDocument.InvokeScript after the page finishes loading. To call into .NET from JavaScript expose a COM-visible object via WebBrowser.ObjectForScripting and call it as window.external. Remember to set ObjectForScripting only after the control is created and mark the target class [ComVisible(true)]. (learn.microsoft.com)

About the Microsoft.JScript error you hit: trying to compile/execute JScript via CodeDomProvider relies on legacy assemblies and can be brittle. For in-process script hosting consider modern, supported alternatives such as Jint (pure C# JS interpreter) or ClearScript (V8 or JScript engines) instead of fighting assembly-binding problems. These projects are actively maintained and easier to deploy. Also keep security in mind: do not expose sensitive host objects to untrusted HTML/scripts. (github.com)

If you prefer a pure Windows control (no HTML), ’s DataGridView suggestion remains valid when you only need tabular UI and .NET-side events.

Why not use a DatagridView instead?
