如何删除显示在tabpage上的picturebox图标控件???

Question

已经实现在tabpage上动态生成picturebox图标,现在需要通过右键上下文菜单的"删除"项来删除该图标,怎么编程实现删除操作?并把结果保存到数据库(图标记录有数据库表单包含的对应信息)?

Answer 1

写一个右键菜单显示的方法，动态生成的时候就指定pic的右键
 private void Form3_Load(object sender, EventArgs e)
        {            PictureBox pic1 = new PictureBox();
            this.panel1.Controls.Add(pic1);
            pic1.MouseUp += new MouseEventHandler(pic_MouseUp);
            
        }        void pic_MouseUp(object sender, MouseEventArgs e)
        {
            this.contextMenuStrip1.Show();
            this.contextMenuStrip1.Top = e.Y;
            this.contextMenuStrip1.Left = e.X;
            string name = ((PictureBox)sender).Name;
            //知道了name，就可以操纵pic了，然后把他从panel中删除
            this.panel1.Controls.Remove((PictureBox)sender);
            
        }
