我尝试过：

i need delete my datas in FLP with double click. How to do it?

What I have tried:

public void Show()
        {
            flowLayoutPanel1.Controls.Clear();
            if (comboBox1.SelectedItem != null)
            {
                foreach (Group item in Controller.groups)
                {
                    GroupBox elm = new GroupBox();
                    elm.BackColor = Color.YellowGreen;
                    elm.Text = item.teacher;
                    elm.AutoSize = true;
                    elm.MinimumSize = new Size(150, 150);
                    Label lb = new Label();
                    lb.Location = new Point(0, 15);
                    lb.Text = "Group Name: " + item.group_name + "\n" + "Hours: " + item.hours;
                    elm.Controls.Add(lb);
                    lb.AutoSize = true;
                    flowLayoutPanel1.Controls.Add(elm);
                   
                }
            }
        }

private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
        {
            this.Show();
        }

推荐答案

双击偶数通常不用于删除操作。在几乎我见过/写过的每个应用程序中，删除项目需要用户右键单击所需的项目，然后从后续的上下文菜单中选择删除。重新考虑你的设计。

The double-click even is not typically used for a delete action. In pretty much every app I've ever seen/written, deleting an item required the user to right click the desired item(s), and then select "Delete" from the subsequent context menu. Reconsider your design.
