ultrawebgrid 怎么用tab键来获得焦点

页面上有个ultrawebgrid 控件和一些按钮，现在客户要求用键盘来操作
按钮和ultrawebgrid 都设置了tabIndex
要的是用tab键时ultrawebgrid 要获得焦点，并且要把ultrawebgrid 的第一行（默认）选中，并且可以用键盘的上下键来选择数据，现在的问题是 我已经做到了用tab键切换时选中了ultrawebgrid 的一行数据，但是此时tabIndex已经移到了下一个按钮上了，无法用上下键来选择数据，不知道描述清楚了没，请大家帮忙！<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %><%@ Register Assembly="Infragistics35.WebUI.UltraWebGrid.v9.2, Version=9.2.20092.1003, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb"
