MDI问题

Question

子界面:
      namespace csglTest
   {
       partial class Form_Search : Form
      {
          public Form_Search(csglTest.Form_Main parent)
          {
            InitializeComponent();
            this.MdiParent = parent;
          }
      }
   }主界面:
namespace csglTest
{
    partial class Form_Main : Form
    {
        public Form_Main()
        {
            InitializeComponent();
        }
    }
}菜单中查找项:        private void 查找ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            csglTest.Form_Search form_search = new csglTest.Form_Search(this);
            form_search.Show();
        }主界面IsMdiContainer已经设为True,点击菜单查找项却没有子界面出来,怎么回事??调试时发现form_search确实生成了...但是就是显示不出来...

呵呵，刚才写错了，作为补偿给你一个我的，可能对你有帮助~
public partial class MainForm : Form
    {
        private studentAddForm f1 = new studentAddForm();
        private studentSearchForm f2 = new studentSearchForm();
        public MainForm()
        {
            InitializeComponent();
        }        private void 添加学生ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            if (f1.IsDisposed)
            {
                f1 = new studentAddForm();
            }
            else
            {
                ;
            }
            f1.MdiParent = this;
            f1.Show();
            f1.Focus();
        }        private void 退出ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            this.Close();
        }        private void 查询学生ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            if (f2.IsDisposed)
            {
                f2 = new studentSearchForm();
            }
            else
            {
                ;
            }
            f2.MdiParent = this;
            f2.Show();
            f2.Focus();
        }
    }
