           请选择
                                                   
          
           借出
                                                   
          
           租出
                                                   
          
           毁损
                                                  
          
           盘亏
                                               
                                          
                                         
                                             
                                          
                                     
                                
                               
                               
                               
                               
                               
                               
                           
     

后台获取行索引：

protected void DropDownList3_SelectedIndexChanged(object sender, EventArgs e)     {
   int i; var dropDown = sender as DropDownList;         TableCell cell = null; if (dropDown != null)         {
               cell = dropDown.Parent as TableCell; var row = cell.Parent as GridViewRow;             i = row.RowIndex;            string  guid = GridView3.Rows[i].Cells[1].Text;//获取当前行的guid if (dropDown.SelectedValue == "借出")             {
                   Response.Write("  ");             }         }             }
