请教大家:
自定义的ToolStripMenuItem 如何在 XXXXXXXXXXXXXXXXXXXXXXXXXXX位置实现checked状态的改变.
 ToolStripMenuItem DevMenu = new ToolStripMenuItem();
 DevMenu = new ToolStripMenuItem();
 for (i = 0; i < al.Count; i++)
 {
       DevIncludeM[i] = new ToolStripMenuItem();
       DevIncludeM[i].Name = al[i].ToString();
       DevIncludeM[i].Text = al[i].ToString();
       DevIncludeM[i].Click += new EventHandler(DevIncludeM_Click);        
 } private void DevIncludeM_Click(object sender, EventArgs e)
 {
        switch (((System.Windows.Forms.ToolStripDropDownItem)sender).Text)
        {
           case "快捷工具条" :
               XXXXXXXXXXXXXXXXXXXXXXXXXXX
                break;
        }
}
