大家帮忙看看这是怎么会事？？

在form1中定义了几个botton控件，按下以后进入form2，form2定义了一个toolbar控件，一个datagrid控件，在toolbal控件的“增加”按下后进入form3，form3定义了“保存”和“取消”按钮，输入完数据以后，按“取消”，我想退到form2，可却退到了form1，请问这是怎么回事？？
以下是toolbar控件程序
private void toolBar1_ButtonClick(object sender, System.Windows.Forms.ToolBarButtonClickEventArgs e)
{
switch(toolBar1.Buttons.IndexOf(e.Button))
{
case 0:
AddBrch AddBrchForm = new AddBrch();
AddBrchForm.myParent=this;
AddBrchForm.Show();
brchDataSet = lib.ExecuteGet("select brno,brname from brtable order by brno","brtable");
lib.FillDataGridbyDataSet(dataGrid1,brchDataSet,ftpFieldName,ftpFieldLenth);
break;
case 1:
string brchDel,brchDelSql;
brchDel=dataGrid1[dataGrid1.CurrentRowIndex,0].ToString();
string SavePath="c:\\\\mapsgl\\\\data\\\\"+brchDel;

brchDelSql="delete from brtable where brno = "+lib.rep(brchDel);

MessageBox.Show(SavePath);
MessageBox.Show(brchDelSql);

lib.ExecuteUpdate(brchDelSql);
Directory.Delete(SavePath);

brchDataSet = lib.ExecuteGet("select brno,brname from brtable","brtable");
lib.FillDataGridbyDataSet(dataGrid1,brchDataSet,ftpFieldName,ftpFieldLenth);

break;
case 2:
this.Close();

break;
}
以下为保存和取消的程序
private void button1_Click(object sender, System.EventArgs e)
{
string SavePath="c:\\\\mapsgl\\\\data\\\\"+textBox1.Text.Trim();
string SavePath1="\'"+"c:\\\\mapsgl\\\\data\\\\"+textBox1.Text.Trim()+"\'";
string addBrchSql="insert into brtable values ("+brchLib.rep(textBox1.Text)+","+brchLib.rep(textBox2.Text)+","+SavePath1+")";
//MessageBox.Show(SavePath1);
Directory.CreateDirectory(SavePath);
//MessageBox.Show(addBrchSql);
brchLib.ExecuteUpdate(addBrchSql);
textBox1.Text="";
textBox2.Text="";
MessageBox.Show("增加成功");
this.textBox1.Focus();
}

private void button2_Click(object sender, System.EventArgs e)
{

this.Close();

}
}

没用

层次太多了；

试试ShowModal()

AddBrchForm.myParent=this;
把这一句注释掉看看。
