Label Click Event

c#, mouseclick-event

Solution

Your `LB` object is out of scope, you need to move it within the loop. (Also, the handler you've shown is called `LB_Click` but you're trying to assign `PB_Click`; I assume that was a typo).

foreach (var listBoxItem in listBox1.Items)
{
    Label LB = new Label();
    LB.Name = "Label" + listBoxItem.ToString();
    LB.Location = new Point(257, (51 * lbl) + 25);
    LB.Size = new Size(500, 13);
    LB.Text = listBoxItem.ToString();
    LB.Click += new EventHandler(LB_Click); //assign click handler
    Controls.Add(LB);

    lbl++;
}

The `sender` in your event handler will be the label that was clicked.

protected void LB_Click(object sender, EventArgs e)
{
    //attempt to cast the sender as a label
    Label lbl = sender as Label; 

    //if the cast was successful (i.e. not null), navigate to the site
    if(lbl != null)
        webBrowser1.Navigate("http://www.mysite/" + lbl.Text);
}

Problem

I am trying too create a click event for a group of lables that are created dynamically like this: ``` private void AddLBL_Btn_Click(object sender, EventArgs e) { int ListCount = listBox1.Items.Count; int lbl = 0; foreach (var listBoxItem in listBox1.Items) { Label LB = new Label(); LB.Name = "Label" + listBoxItem.ToString(); LB.Location = new Point(257, (51 * lbl) + 25); LB.Size = new Size(500, 13); LB.Text = listBoxItem.ToString(); Controls.Add(LB); lbl++; } LB.Click += new EventHandler(PB_Click);// error here } protected void LB_Click(object sender, EventArgs e) { webBrowser1.Navigate("http://www.mysite/" + LB);//Navigate to site on label } ``` I am getting an error: "The name 'LB' does not exist in the current context" becauseI am creating LB within the loop and I am not smart enough to know how to declare LB so I can use it outside the loop. Additionally, I would like to pass to the label name (listBoxItem) on to the click event and have it where LB is in the WebBrowser call is. Like: webBrowser1.Navigate("http://www.mysite/" + LB);//Navigate to site on label
