JS文件源码：GridColorControl.js
=====================================
/*-----------------调用说明-----------------
说明：可用于架设页面事件。
入口函数：OnFocusSet(....)
如：OnFocusSet( "#000000","#FFFFFF","#FFFFFF","#000000" )
实用调用例子：
鼠标事件：
onMouseOver='OnFocusSet( "#000000","#FFFFFF","#FFFFFF","#000000" )'
单击事件：
onClick='OnFocusSet( "#000000","#FFFFFF","#FFFFFF","#000000" )'
参数说明：
参数一[color]:未选中时的字体颜色
参数二[backColor]:未选中时的背景颜色
参数三[selectColor]:选中时的字体颜色
参数四[selectBackColor]:选中时的背景颜色

/*---------主函数入口----------*/

}
===========================================
后台DataGrid梆定方法：
===========================================
private void dgList_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
if( e.Item.ItemType==ListItemType.Item || e.Item.ItemType==ListItemType.AlternatingItem || e.Item.ItemType==ListItemType.SelectedItem)
{
e.Item.Attributes.Add("onClick","OnFocusSet( '#000000','#FFFFFF','#FFFFFF','#000000' );");
}
}
===========================================
前台.aspx文件调用JS即可：
<script language="javascript" src="GridColorControl.js"></script>
