<asp:Panel ID="foo" runat="server"></asp:Panel>

Then in your code behind....

foo.Attributes.Add("style", "border: 1px solid");

You can use either xyz.Attributes.Add("style", "display: block") or xyz.Attributes["style"] = "display: block".

FYI: You do not need to use FindControl unless xyz is located inside Data controls like Repeater.

<div id="xyz" style="display: none" runat="server">
    Please Register YourSelf First
</div>
<asp:Button runat="server" ID="SubmitButton"
    OnClick="SubmitButton_Click" Text="Submit" />

protected void SubmitButton_Click(object sender, EventArgs e)
{
    xyz.Attributes.Add("style", "display: block");
}
