DevExpress的双击获取单元格数据

1、设置 GirdViewt.OptionsBehavior.Editable = false;
设定变量 DevExpress.XtraGrid.Views.Grid.ViewInfo.GridHitInfo hInfo = new DevExpress.XtraGrid.Views.Grid.ViewInfo.GridHitInfo(); //获取“撞击点”的位置
2、注册GridView的鼠标单击及GridView的双击事件
this.gridView.MouseDown += new MouseEventHandler(gridView_MouseDown); //用于获取GridHitInfo-撞击点的信息
this.gridView.DoubleClick += new EventHandler(gridView_DoubleClick);//双击事件
3、代码
//鼠标单击事件

        //获取鼠标点击的位置
        void gridView_InpatientPatient_MouseDown(object sender, MouseEventArgs e)
        {
            hInfo = gridView_InpatientPatient.CalcHitInfo(e.X, e.Y); 
        }

//界面双击的事件

        //双击事件
        void gridView_DoubleClick(object sender, EventArgs e)
        {
	    //获取点
            if (gridView.FocusedRowHandle < 0) return;
            try
            {
                //双击某一单元格，执行代码  
                if (hInfo.InRowCell)
                {
                    //获取
                    int rowid = this.gridView.FocusedRowHandle;

                    string selectedStr = this.gridView.GetRowCellValue(rowid, "PatientID").ToString();

                    MessageBox.Show(selectedStr);
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }  
        }
