Hi Imar. Couple of warnings and errors that i cant seem to get past. Im at the end of Chapter 6.

Error 3 The 'ID' property of a control type System.Web.UI.WebControls.Button cannot be applied through a control skin. c:\BegASPNET\Site\App_Themes\Monochrome\Button.ski n 1
Error 4 The 'ID' property of a control type System.Web.UI.WebControls.Button cannot be applied through a control skin. c:\BegASPNET\Site\App_Themes\Monochrome\Button.ski n 2

Warning 1 C:\Documents and Settings\123163\Desktop\Work Books\Beginning ASP.net in C# (Code)\Source\Chapter 06\App_Themes\Monochrome\Button.skin: ASP.NET runtime error: There is no build provider registered for the extension '.skin'. You can register one in the <compilation><buildProviders> section in machine.config or web.config. Make sure is has a BuildProviderAppliesToAttribute attribute which includes the value 'Web' or 'All'. C:\Documents and Settings\123163\Desktop\Work Books\Beginning ASP.net in C# (Code)\Source\Chapter 06\App_Themes\Monochrome\Button.skin 1 1 Miscellaneous Files

I've checked online and attempted the following fix to no avail. Added this code to web.config:

Code:

<buildProviders>

<add extension=".skin" type="System.Web.Compilation.PageBuildProvider"/>

</buildProviders>

Hi there,

For the erorr message take a look at page 223, second paragraph:

Quote:

First of all, the control in the skin file cannot have an ID attribute.

and page 235 start of the TIO:

Quote:

Be aware that if you copy and paste a skin definition, VWD automatically adds an ID attribute (that is, if you connected skin files to the User Control Editor as described earlier). This ID is not allowed, so you need to remove it.

For the warning, check out page 234, below point 4:

Quote:

With this setting on, you may get a warning in the Error List about build providers when you have a skin file open. You can safely ignore this error, because skins work fine at runtime even with these settings in VWD.

Hope this helps,

Imar
