Chapter 6 page 230 SkinsDemo

mc48864 · January 29th, 2010, 10:32 PM

The skins demo project is not working for me. I cannot debut until I am certain what I should have done. I apologize, since no one else posted about this I am certain the problem is me. Never the less, clarification is what I need.
From the text "Try It Out #4"
~~~~~
Create a new Web Form in the Demos folder and call it SkinsDemo.aspx. Make sure you base it on the exported template you created earlier...
~~~~~

The only thing I can reference about an exported template is the BasePage template. I assume that we do not want a web form and we do want a copy of the BasePage template file. However, when I look back at page 212 #9 is not clear if you select the template file or not before renaming it TestPage.aspx.

So anyway, I build the SkinsDemo file using the BasePage template file and I get an error:

Error 1 Make sure that the class defined in this code file matches the 'inherits' attribute, and that it extends the correct base class (e.g. Page or UserControl). C:\Users\Michael\Documents\Visual Studio 2008\WebSites\BegASPNET\Site\demos\SkinsDemo.aspx. cs 14 33 C:\...\Site\
That line happens to be:
public partial class SkinsDemo

Changing that line to:
public partial class _Default : BasePage

Returns an error about the wrong file being referenced

Changing that line to match default.aspx:
public partial class _Default : BasePage

Results back to the first error about inheritance. The demos/SkinsDemo/aspx file top line reads: Inherits="SkinsDemo"

I am more than a bit lost as to what I have done wrong. I hope this is not confusing, I have been at this a while.

Could it be my .net version? Here is the browser output, last line reads .net 2.0.

Server Error in '/Site' Application.

Disregard, the solution was change:

public partial class SkinsDemo

To:

public partial class SkinsDemo : BasePage

I thought basing the form on the BasePage Template wrote this line.

Yes, it should. Looks like your template is not OK. You may want to consider recreating it. Here's a run-down of what you need to do:

1. Add a new Web Form to the site using the Add New Item dialog
2. Make any changes you want to appear in new web forms
3. Replace the class placeholders and change System.Web,.UI.Page to BasePage
4. Choose File | Export Template
5. Delete the web form you created in step 1 from the site
6. To base a new page on your template, choose Add New Item and choose your template

The new Web Form based on the template should now have the code you added or modified in steps 2 and 3.

Hope this helps,

Imar

Thank you for reading all that. It was a great learning oppotunity for me as well.

Imar · January 31st, 2010, 05:34 AM

But is it working now? Did you manage to fix the Web Form template?

Imar

mc48864 · January 31st, 2010, 03:30 PM

Thank you Imar,

Yes, I did get that fixed just a while ago. Don't worry, I promise to have other questions to provide a diversion from your writing in the very near future.
