完成功能是DataGrid的页面选中事件、鼠标事件、双击事件改变TR的色彩。代码很简单，只是一点JS操作。

JS文件:GridControl.js
=============================

/*------------ DataGrid鼠标事件处理 ------------
功能:用于数据梆定后鼠标事件
参数说明:
obj:对像this
fontColor:字体颜色
backColor:背景颜色
----------------------------------------------*/

var objState

//------------鼠标经过时-----------
function OnFoucsMouseOver( obj,fontColor,backColor )
{
if ( obj.rowIndex > 0 )
{
obj.style.color = fontColor;
obj.style.backgroundColor = backColor;
}
}

//-----------鼠标离开时-----------
function OnFoucsMouseOut( obj,fontColor,backColor )
{
if ( obj.rowIndex > 0 )
{
if ( obj != objState )
{
obj.style.color = fontColor;
obj.style.backgroundColor = backColor;
}
}
}

//-----------鼠标单击时-----------
function OnFoucsClick( obj,fontColor,backColor )
{
if ( obj.rowIndex > 0 )
{
if ( objState != null )
{
objState.style.color = "";
objState.style.backgroundColor = "";
}
obj.style.color = fontColor;
obj.style.backgroundColor = backColor;

objState = obj;
}
}

//-----------鼠标双击时-----------
function OnFoucsDbClick( obj,fontColor,backColor,openUrl )
{
//参数openUrl为要开的新窗口的地址
if ( obj.rowIndex > 0 )
{
if ( objState != null )
{
objState.style.color = "";
objState.style.backgroundColor = "";
}
obj.style.color = fontColor;
obj.style.backgroundColor = backColor;

objState = obj;

window.open( openUrl );
}
}

后台数据梆定例子：

==========================================

private void dgList_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
//
if ( e.Item.ItemIndex != -1 )
{
e.Item.Attributes.Add( "onMouseOver","OnFoucsMouseOver(this,'#FFFFFF','#000000');" );
e.Item.Attributes.Add( "onMouseOut","OnFoucsMouseOut(this,'#000000','#FFFFFF');" );
e.Item.Attributes.Add( "onClick","OnFoucsClick( this,'#FFFFFF','#000000' );" );
e.Item.Attributes.Add( "onDblClick","OnFoucsDbClick( this,'#FFFFFF','#000000','about:bank' );" );
}
}

==========================================

前台.aspx页面调用JS文件：

<script language="javascript" src="GridControl.js"></script>
