找了半天scroll,結果卻是TopRowIndex的事。
1、觸發GridView_TopRowChanged()事件

2、設定TopRowIndex

       int topIndex = -1;
       private void gridView2_TopRowChanged(object sender, EventArgs e)
        {
            topIndex = gridView2.TopRowIndex;
        }
        private void refreshView2()
        {
            string
 
 sql = "select * from [A資料分析表]";
            DataTable dt= db.GetTable(sql);
            gridControl2.DataSource = dt;
            gridView2.TopRowIndex = topIndex;//就是這句
        }

        private void button1_Click(object sender, EventArgs e)
        {
            refreshView2();
        }
