做的是一个图片列表的显示,想实现,当鼠标移动都某行时候,出现一个层或者panel,显示该行对应的图片。
鼠标移开时候又消失。
谢谢
是不是用ajax比较简单呢
用那个控件呢,怎么和gridview结合呢,谢谢

解决方案 »

  1.   

    动态添加不就可以吗?
    搞个Div
    就可以实现,当选中某一行的时候把,对应的值传过去!!
    调用出图片就ok了!
      

  2.   

    gridview绑定事件里做就可以了,先隐藏所有的
    e.Item.Atributes.Add("onmouseover","document.getElementById('div" + e.ItemIndex.ToString() + "').style.visibility='visible'")
    e.Item.Atributes.Add("onmouseout","document.getElementById('div" + e.ItemIndex.ToString() + "').style.visibility='hidden'")
