c# – 在父窗体上启用滚动条

我有以下问题.基于图像
子表单上的某些控件无法正确显示.我也不能在子窗体上使用Autoscroll设置为true,因为它的一些控件是锚定在底部.
我想的修复是当子表单的高度重叠时在父表单上有一个滚动条.我应该在我的代码上添加什么来使父表单有一个滚动条？

我使用此代码在父窗体中显示子窗体.

void ParentButtonClickNew(){

  ChildForm entry = new ChildForm();
  LoadChildForm(entry,this); 
}



 public void LoadChildForm(object childForm,object container)
    {
        System.Windows.Forms.Form xForm = (System.Windows.Forms.Form)childForm;
        System.Windows.Forms.Control control = (System.Windows.Forms.Control)container;

        xForm.TopLevel = false;

        if (control.Controls.Count == 0)
        {
            xForm.Parent = control;
            xForm.StartPosition = FormStartPosition.CenterScreen;
            //xForm.WindowState = System.Windows.Forms.FormWindowState.Maximized;
            xForm.Show();
            xForm.BringToFront();

        }
        else
        {
            bool isFound = false;
            for (int i = 0; i <= control.Controls.Count - 1; i++)
