i在ChildForm按钮上使用此代码

i have panel control on ParentForm, i opened the ChildForm on panl control and from ChildForm i want to open ThirdForm on panel control of ParentForm


i used this code on the button of ChildForm

ParentForm panel = new ParentForm();

推荐答案

((System.Windows.Forms.Panel)Application.OpenForms["ParentForm"].Controls["panel_Main"]).Controls.Clear();
                    ThirdForm third = new ThirdForm();
                    third.TopLevel = false;
                    third.AutoScroll = true;
                    third.Dock = DockStyle.Fill;
                  ((System.Windows.Forms.Panel)Application.OpenForms["ParentForm"].Controls["panel_Main"]).Controls.Add(student);
                    third.Show();
