Question

I have a listbox on my website, which contains some elements.

I made the event, OnSelectedIndexChanged, so when the user presses an element, this value will be put into a textbox

protected void Page_Load(object sender, EventArgs e)
{

    listbox = new Listbox();

    // Add to page etc.

    listbox.SelectedIndexChanged += new EventHandler(listbox_SelectedIndexChanged);

}

void listbox_SelectedIndexChanged(object sender, EventArgs e)
{
    try
    {
        textbox_name.Text = listbox.SelectedItem.ToString();
    }
    catch
    {
        textbox_info.Text = "Choose employee";
    }
}

It works in c# windows forms, but not in web forms for some reason.

Is it possible to get it to work?

Thank you
