SharePoint Development help

Hi,

we had a Custom List Context menu Item in "Actions menu" in SP 2007. and below is the class we used for that. Now if I would like to use the same code for SP 2010, then What will be my eqquivalent Code with SP Ribbon. For your Reference I am also including the Custom Action XML that we used in 2007. Basically, this code used to Create a menu item on the "Actions Menu" of either a document Library or any type of list. So, I am looking for a Button on the List Tab, that appears on all List Views for list and all Views of Document Library. When a user Clicks on that Button then the user is directed to a URL mentioned in the Code below. Let me know if it is not clear or need more info.



Custom Action XML:

<CustomAction Id="SomeCustom.Action" Location="Microsoft.SharePoint.StandardMenu" GroupId="ActionsMenu" Sequence="20" ControlAssembly="Some Key" ControlClass="Class mentioned below" />

Class Referenced in Above CustomXML

using System;

using System.Collections.Generic;

using System.Text;

using System.Web.UI;

using System.Web.UI.WebControls;

using Microsoft.SharePoint;

using Microsoft.SharePoint.WebControls;

namespace MyNameSpace

{

public class MyClass : WebControl

{

protected override void OnLoad(EventArgs e)

{

EnsureChildControls();

base.OnLoad(e);

}

protected override void CreateChildControls()

{

ListViewWebPart listView = FindListView(Parent);

if (listView == null)

return;


MenuItemTemplate menu = new MenuItemTemplate();

menu.Title = "My Title";

menu.Text = "My Title";

menu.Description = "My Description";

menu.ImageUrl = "/_layouts/images/lg_icasax.gif";

menu.Sequence = 20;



SPWeb web = SPContext.Current.Web;



string urlFormat = "someURL";

string fullUrl = string.Format(urlFormat,

web.Url,

listView.ListName,

listView.ViewGuid,


System.Web.HttpUtility.UrlEncode(filterString)

);

menu.ClientOnClickScript = fullUrl;

Controls.Add(menu);

base.CreateChildControls();

}



}

}

Thanks in Advance,
