Why doesn't the value of my textbox change when I click on a radio button in ASP.NET?
<p>I'm trying to change the value of my textbox by clicking on a radio button. But when I click on that radio button, nothing happens! Does someone know why? Here is the code: </p>

<pre><code>protected void rbOpgelost_CheckedChanged(object sender, EventArgs e)
{
    tbEinddatum.Text = DateTime.Now.ToString();
}
</code></pre>
