Dynamically generating events in c#?

I generate a bunch of linkLabels in c#. What I want is to fill textBox1 with an URL, which is different with each linkLabel. How would I generate dynamic events? This is an example:

foreach (var node in nodes)
{
    HtmlAttribute att = node.Attributes["href"];
    HtmlAgilityPack.HtmlDocument tempDoc = new HtmlAgilityPack.HtmlDocument();
    tempDoc.LoadHtml(node.InnerHtml);
    var tempNode = tempDoc.DocumentNode.SelectSingleNode("//img[@alt]");
    HtmlAttribute tempAtt = tempNode.Attributes["alt"];
    LinkLabel ll = new LinkLabel();
    ll.Location = new Point(20, 20 * i);
    ll.Text = tempAtt.Value;
    this.Controls.Add(ll);
    i++;
}

The node text should be tempAtt.Value, and on click the textBox1 should be filled with att.Value

You cannot pass dat to the event directly, you'll have to get at it from inside the handler some other way. 

foreach (var node in nodes)
{
    ...
    LinkLabel ll = new LinkLabel();
    ...
    ll.Click += MyLabelClickHandler;
    this.Controls.Add(ll);

    i++;
}

void MyLabelClickHandler(object sender, Eventargs e)
{
    senderLabel = sender as LinkLabel;
    string text = senderlabel.text;
    ....
}
