经过一个月来的学习，我总结了用过的几个有关于DataGrid的小技巧：

1.       为每列绑定相应的ToolTip，让其显示相关的信息。（如图）

实现代码：

                                                             private void O_dataGrid_ItemDataBound(object sender,

                           System.Web.UI.WebControls.DataGridItemEventArgs e)

       {

              if(e.Item.ItemType == ListItemType.AlternatingItem ||

                            e.Item.ItemType == ListItemType.Item)

              {

                     WebControl V_wc = (WebControl)e.Item.Cells[1].Controls[0];

                     V_wc.ToolTip = "库存量为 "+e.Item.Cells[4].Text+" 个单位";

              }

       }

2．鼠标移动到某一行动态显示不同的颜色。（如上图）

private void O_dataGrid_ItemDataBound(object sender,

System.Web.UI.WebControls.DataGridItemEventArgs e)

       {

              if(e.Item.ItemType == ListItemType.AlternatingItem ||

                            e.Item.ItemType == ListItemType.Item)

              {

               e.Item.Attributes.Add("onmouseover","this.style.backgroundColor='#FFC66C'");

               e.Item.Attributes.Add("onmouseout","this.style.backgroundColor='#FFFFFF'");

                     }

       }

3. 如果DataGrid的项是用样式来确定显示颜色的，代码为：

private void O_dataGrid_ItemDataBound(object sender,

System.Web.UI.WebControls.DataGridItemEventArgs e)

       {

              if(e.Item.ItemType == ListItemType.AlternatingItem ||

                            e.Item.ItemType == ListItemType.Item)

              {

                                                  e.Item.Attributes.Add("onmouseover",

                                                              "javascript:this.oldClassName=this.className;this.className='Over'");

                                                  e.Item.Attributes.Add("onmouseout",

                                                             "javascript:this.className=this.oldClassName");

               }

       }
