C# Devexpress 中GridControl多行数据拖拽(转)

using DevExpress.XtraGrid.Views.Grid.ViewInfo;

 private GridHitInfo downHitInfo;

设置多行选中

 GridView1.OptionsSelection.MultiSelect = true;

//事件处理：

//要拖动的数据

        {

                downHitInfo.HitPoint.X - SystemInformation.DragSize.Width / 2,
                downHitInfo.HitPoint.Y - SystemInformation.DragSize.Height / 2), SystemInformation.DragSize);

                GridControl1.DoDragDrop(row, DragDropEffects.Copy);
            }

//要存放的GridControl

// 设置为可接受拖拽数据
