新手！页面间传值有关问题_ASP.NET

新手求助！！！页面间传值问题~
我想实现这样一功能求教！！
两页面：web1,web2;
web1中一Gridview控件：列Id,Name,Button按钮；

<asp:Button ID="Buttonid" runat="server" Text="ID" OnClientClick="return vv()"/>

function vv()
{
var result=showModalDialog('RepleDetailed.aspx','RepleDetailed','dialogWidth:500px;dialogHeight:400px;center:yes;help:no;resizable:no;status:no');
}

点击按钮跳到网页对话框web2并传以Gridview列的Id值;
web2接收Id

------解决方案--------------------------------------------------------

C# code

<asp:Button ID="Buttonid" runat="server" Text="ID" OnClientClick='vv(<%#Eval("id")%>)'/>function vv(val)    {     var result=showModalDialog('RepleDetailed.aspx?id='+val,'RepleDetailed','dialogWidth:500px;dialogHeight:400px;center:yes;help:no;resizable:no;status:no');     }
