.NET WebBrowser control javascript issue

Question

4.00/5 (1 vote)

See more:

I have HTML based reports that get fed to the WebBrowser control that needs to use javascript.

My issue is that my javascript won't execute when using WebBrowser.DocumentText but, executes fine when using WebBrowser.Navigate.

Does anyone know why this would happen?

Thanks

Example HTML:

XML

<html>
<head>
<title></title>
</head>
<body>
<a href="#" onClick="alert('yeah');">Click Me</a>
</body>
</html>

Must be something else you're doing ( wrong maybe ;) ). I threw toghether this small example and it works exactly as expected:

C#

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace TestWebBrowser
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            webBrowser1.DocumentText = "<html><head><title></title></head><body><a href=\"#\" onClick=\"alert('yeah');\">Click Me</a></body></html>";
        }
    }
}

A simple form with a WebBrowser control on it and a button that makes the control load the HTML you provided via DocumentText. The form shows the ClickMe link and when I click it the alert box springs up with "yeah".
