Dev GridViews 刷新数据后,滚动条保持原来位置

1、滚动条保持原来位置

A方案

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

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

B方案

int k1 = gridView_TheAll.FocusedRowHandle;

gridControl_TheAll.DataSource = null;

gridControl_TheAll.DataSource = Core_GetData();

gridView_TheAll.FocusedRowHandle = k1

2、自动翻页到最后一行

this.gridView2.FocusedRowHandle = this.gridView2.DataRowCount - 1;//焦点转移到最后一行
gridView2.SelectRow(gridView2.RowCount - 1);
