Design View when using an ASP:Panel to show/hide groups of <tr>'s

I have an HTML table in which I am using ASP:Panel controls to group
together <tr>'s so that I can more easily show/hide them (by setting the
ASP:Panel's Visible property). This works fine, but Visual Studio .NET
2005's Design View always hides the <tr>'s regardless of whether the
ASP:Panel's Visible property is set to True, False, or not set at all. Is
there some way I can stop Visual Studio .NET 2005's Design View from hiding
my <tr>'s that are inside ASP:Panel controls? Thanks.

asp:Panel contol usually renders as <div>...</div> tag. It is not suitable
for hiding <tr>s. Use asp:PlaceHolder, which does not have any wrapping
tags.

Would I use the asp:PlaceHolder control the same way? I have never used the
asp:PlaceHolder control before. Would my basic tag layout be the following:

<asp:PlaceHolder>
    <tr>...</tr>
    <tr>...</tr>
    <tr>...</tr>
</asp:PlaceHolder>
<asp:PlaceHolder>
    <tr>...</tr>
    <tr>...</tr>
    <tr>...</tr>
</asp:PlaceHolder>

Thanks.
