How to align objects vertically in ASP.NET?

Question

I have been messing around with asp.net for awhile now and always have issues aligning objects with various heights on the same row. For example, in this case, I have a search label, a text field, then a image button. What is the "proper way" to get these three items to align properly?

My existing code:

<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
   </asp:Content>
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
    <asp:Panel VerticalAlign="Center" runat="server">
    <asp:Label ID="Label1" runat="server" Font-Size="X-Large" Text="Search Tests:"></asp:Label>
    <asp:TextBox ID="searchTextBox" runat="server" Font-Size="X-Large" 
        Height="30px" style="margin-left: 13px; margin-top: 0px" Width="219px"></asp:TextBox>
    <asp:ImageButton ID="ImageButton2" runat="server" Height="45px" 
        ImageUrl="~/Images/SearchButton.PNG" style="margin-left: 18px; margin-top: 0px" 
        Width="95px" />
    </asp:Panel>
</asp:Content>

The easiest is using CSS or tables. I put a div around with a height and vertical align to the top. CSS Reference

<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
    <asp:Panel ID="Panel1" VerticalAlign="Center" runat="server">
        <div style="height: 40px; vertical-align: top">
            <div style="padding-top: 10px; float:left;">
                <asp:Label ID="Label1" runat="server" Font-Size="X-Large" Text="Search Tests:"></asp:Label>
            </div>
            <div style="padding-top: 5px; float:left;">
                <asp:TextBox ID="searchTextBox" runat="server" Font-Size="X-Large" Height="30px"
                     Style="margin-left: 13px; margin-top: 0px" Width="219px"></asp:TextBox>
            </div>
            <div style="padding-top: 5px; float:left;">
                <asp:ImageButton ID="ImageButton2" runat="server" Height="45px" ImageUrl="~/Images/SearchButton.PNG"
                     Style="margin-left: 18px; margin-top: 0px" Width="95px" />
            </div>
        </div>
    </asp:Panel>
</asp:Content>
