本文介绍了一种在DataGridView控件间进行数据选择、转移及刷新的方法。通过C#代码实现，详细展示了如何从左侧DataGridView中选择数据行并将其移至右侧DataGridView，同时保持数据完整性。此外，还提供了刷新数据源的代码示例。

        private void BTNRight_Click(object sender, EventArgs e)
        {
            int[] rows = this.gvdemand1.GetSelectedRows();
            DataTable dtselect = null;
            for (int i = 0; i < rows.Length; i++)
            {
                if (rows[i] >= 0)
                {
                    DataRow dr = gvdemand1.GetDataRow(rows[i]);
                    if (dtselect == null) dtselect = dr.Table.Clone();

                    dtselect.Rows.Add(dr.ItemArray);
                }
            }
            //删除选择数据
            gvdemand1.DeleteSelectedRows();
            //追加到右侧
            DataTable rightDt = (DataTable)gcDemand2.DataSource ;
            if (rightDt == null) rightDt = dtselect.Clone();
            for (int i = 0; i < dtselect.Rows.Count; i++)
            {
                rightDt.NewRow();
                rightDt.ImportRow(dtselect.Rows[i]);
            }
            this.gcDemand2.DataSource = rightDt;
        }

        private void BTNLeft_Click(object sender, EventArgs e)
        {
            int[] rows = this.gvDemand2.GetSelectedRows();
            DataTable dtselect = null;
            for (int i = 0; i < rows.Length; i++)
            {
                if (rows[i] >= 0)
                {
                    DataRow dr = gvDemand2.GetDataRow(rows[i]);
                    if (dtselect == null) dtselect = dr.Table.Clone();

                    dtselect.Rows.Add(dr.ItemArray);
                }
            }
            //删除选择数据
            gvDemand2.DeleteSelectedRows();
            //追加到左侧
            DataTable LeftDt = (DataTable)gcDemand1.DataSource;
            if (LeftDt == null) LeftDt = dtselect.Clone();
            for (int i = 0; i < dtselect.Rows.Count; i++)
            {
                LeftDt.NewRow();
                LeftDt.ImportRow(dtselect.Rows[i]);
            }
            this.gcDemand1.DataSource = LeftDt;
        }
        //刷新数据
        private void BTNRefresh_Click(object sender, EventArgs e)
        {
            GetInstance();
            this.gcDemand2.DataSource = null;
        }
