DataRowView curRow = (DataRowView)curDataItem.DataItem;//把获取的行转化为DataRowView对象
int id = int.Parse(curRow["id"].ToString());
String imageUrl = ShowImageBll.getImageUrlByID(id);
HtmlTable myTable = (HtmlTable)curDataItem.FindControl("myTable");//获取ItemTemplate模板中的Table控件
myTable.Attributes.Add("onMouseOver", "SetNewColor(this);ShowPhoto('"+imageUrl+"');");
myTable.Attributes.Add("onMouseOut", "SetOldColor(this);ShowPhoto('image/20131129.jpg');");
}
}
总结：
【1】前段HTML的Table控件 定义： <table id="myTable" border="1" cellpadding="5" cellspacing="0" runat="server">
后端获取时：HtmlTable myTable = (HtmlTable)curDataItem.FindControl("myTable");//获取ItemTemplate模板中的Table控件
（此时需要添加引用using System.Web.UI.HtmlControls;）
【2】ListViewDataItem curDataItem = (ListViewDataItem)e.Item; //把目前的项目转化为一个ListViewDataItem
DataRowView curRow = (DataRowView)curDataItem.DataItem;//把获取的ListViewItem对象所绑定的数据转化为DataRowView对象
【3】遗留的问题：背景颜色的切换不起作用。函数SetNewColor(this)或者设置在aspx页面内嵌javascript也不起作用
