Answer 1

部分代码
        private void dataGridView1_Scroll(object sender, ScrollEventArgs e)
        {
            //当dataGridView1滚动条移动时treeView1控件隐藏
            treeView1.Visible = false;
        }
        private void dataGridView1_ColumnWidthChanged(object sender, DataGridViewColumnEventArgs e)
        {
            //当dataGridView1的列宽改变时treeView1控件隐藏
            treeView1.Visible = false;
        }
        private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
        {
            DataGridView dgv = (DataGridView)sender;
            if (dgv.Columns[e.ColumnIndex].Name == "userlimit" &&
            dgv.Columns[e.ColumnIndex] is DataGridViewComboBoxColumn)
            {
                Rectangle rect = dgv.GetCellDisplayRectangle(dgv.CurrentCell.ColumnIndex, dgv.CurrentCell.RowIndex, false);
                treeView1.Visible = true;
                treeView1.Top = rect.Top+rect.Height +dgv.Top ;                treeView1.Left = rect.Left;                //treeView1.Height = rect.Height;                treeView1.Width = rect.Width;            }
        }treeView1.Visible = false;  不管用？？
