Chapter 12, Try It Out, p.454, bad TagPrefix

VictorVictor · February 23rd, 2006, 01:29 PM

On page 455, Line 7. 'There appears on the first Register line (not greyed out)
<%@ Register TagPrefx="uc1" ... %>, in the book. This should not be TagPrefix="uc1" because it will conflict with the use of "uc1" on the next line.

I note that the compiler correctly makes this literal "wu" instead of what the book says, so this is a minor typo.

Can you tells us what's on "the next line"?

If that line jas another <%@ Register declaration, it's no problem. It's not an error to set up multiple controls with the same Tax Prefix (asp:* controls do that all the time).

So, this would work fine:

<%@ Register Src="About.ascx" TagName="About" TagPrefix="uc1" %>
<%@ Register Src="Details.ascx" TagName="Details" TagPrefix="uc1" %>
<%@ Register Src="MainMenu.ascx" TagName="MainMenu" TagPrefix="uc1" %>

<uc1:About ID="About1" runat="server" />
<uc1:Details ID="Details1" runat="server" />
<uc1:MainMenu ID="MainMenu1" runat="server" />

HtH,

Imar:
Yes, the next line is another Register statement but with a different TagName.
I stand corrected. I don't recall seeing a write-up explaining the details of
the Register statement in my learning experience. My next book after this one
willbe the Professional ASP.NET 2.0. Perhaps it's explained in more detail there.
Thanks.

You're welcome.

Fact is, it doesn't really matter what prefix you use. I usually prefix them with the company name, or an abbreviation of that....

Cheers,
