asp.net自带MultiView 控件使用问题

<form id="form1" runat="server">

    <div style="height:100%; width:100%;">

        <asp:Menu ID="Menu1"  runat="server" Orientation="Horizontal" StaticEnableDefaultPopOutImage="False" OnMenuItemClick="Menu1_MenuItemClick"> 



        <Items>



    <asp:MenuItem ImageUrl=""  Text="页面A" Value="0"></asp:MenuItem>



    <asp:MenuItem ImageUrl="" Text="页面B" Value="1"></asp:MenuItem>

</Items>



</asp:Menu>

 

        <asp:MultiView ID="MultiView1" runat="server" ActiveViewIndex="0" >

            <asp:View ID="View1" runat="server">

                <iframe src="gatewayEventEdit.aspx?gatewayaddress=<%=Request.QueryString["gatewayaddress"].ToString() %>" width="100%"  height="100%"></iframe>

            </asp:View>

            <asp:View ID="View2" runat="server">

                <iframe src="xunjianresult.aspx" width="100%" height="100%"></iframe>

            </asp:View>

        </asp:MultiView>

    

    </div>

    </form>

 protected void Menu1_MenuItemClick(object sender, EventArgs e)

        {

            if (Menu1.SelectedValue.Equals("0"))

            {

                MultiView1.ActiveViewIndex = 0;

               

            }

            else

            {

                MultiView1.ActiveViewIndex = 1;

                

            }

        }

怎么进到 View1和View2对应的页面的里面，这两个页面的显示的内容都只占了页面的高度一半啊、、、

如何弄啊？

------解决方案--------------------
什么意思？各设他们的Height="50%"
------解决方案--------------------
设置一下 style='height:xxxpx'
顶一下，账号没了，没分了
