我想实现单击各选项卡，触发状态栏的labe显示当前选项卡内picturebox的图片文件完整路径。怎么实现呢？
（其中，各选项卡是动态生成的）
 private void 打开OToolStripMenuItem_Click(object sender, EventArgs e)
        {
            if (openFileDialog1.ShowDialog() == DialogResult.OK)
            {
                foreach (var item in openFileDialog1.FileNames)
                {
                    TabPage tp = new TabPage();
                    tp.Text = System.IO.Path.GetFileName(item);
                    PictureBox pb = new PictureBox();
                    pb.Parent = tp;
                    pb.Image = Image.FromFile(item);
                    pb.Dock = DockStyle.Fill;
                    pb.SizeMode = PictureBoxSizeMode.Zoom;
                    tabControl1.TabPages.Add(tp);
                }
                this.tabControl1.SelectTab(tabControl1.TabCount-1);              
            }
        }        private void tabControl1_Selected(object sender, TabControlEventArgs e)
        {
            toolStripStatusLabel1.Text = this.tabControl1.??
