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
------------------------------------------*/
var Rows=new Array();
var ShiftStartRow="";
var setColor,setBackColor,setSelectColor,setSelectBackColor;

/*---------主函数入口----------*/
function OnFocusSet( color,backColor,selectColor,selectBackColor )
{
setColor = color;
setBackColor = backColor;
setSelectColor = selectColor;

//-----------操作----------------

//------------颜色改变------------

}
}

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&
