            </SelectedItemTemplate>
        


.aspx.cs:--

protected void ListView1_SelectedIndexChanged(object sender, EventArgs e)
    {
        //TextBox1.Text = ListView1.SelectedItems[0].Tag.ToString();
        //TextBox1.Text = ListView1.SelectedItemTemplate.ToString ();

        ListViewItem item = ListView1.Items[ListView1.SelectedIndex];
        //fill the text boxes
        TextBox1.Text = item.ToString();
        //textBoxName.Text = item.SubItems[0].Text;




    }

推荐答案

试试这样，

Try like this,

protected void Listview1_SelectedIndexChanged(object sender, EventArgs e)
       {
           TextBox1.Text = (Listview1.Items[Listview1.SelectedIndex].FindControl("Label2") as Label).Text;
       }
