我涉及的DataGrid使用二

1、dataGrid1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)

     /DGridMouseDown/ #region /DGridMouseDown/
        /**//// <summary>
        /// dataGrid1 MouseDown
        /// </summary>
        /// <param name="sender"></param>

        private void dataGrid1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
        {
                        
            //HitTest 方法返回包含所单击区域的行和列的 DataGrid.HitTestInfo 对象
            DataGrid myGrid = (DataGrid) sender;
            System.Windows.Forms.DataGrid.HitTestInfo hti;
            hti = myGrid.HitTest(e.X, e.Y);
        
            switch (hti.Type) 
            {
                case System.Windows.Forms.DataGrid.HitTestType.Cell :
                    if (e.Clicks==2)
                    {
                        //记忆当前行号 
                        currentERowIndex=hti.Row;
                        GetSomeFileName(myGrid,hti.Row);
                        //myGrid.Select(hti.Row);
                    }
                    break;
                case System.Windows.Forms.DataGrid.HitTestType.RowHeader :
                
                    //记忆当前行号 
                    currentERowIndex=hti.Row;
                    GetSomeFileName(myGrid,hti.Row);
    
                    break;
            }

    /**//// <summary>

    try
    {
                acb_YEAR.Text=myGrid[index,1].ToString();
                acb_AREA.Text=myGrid[index,2].ToString();
