Malformed "LINK" Tag in 4.3.0

I have a css function, which adds a (default or custom) css path to the LINK tag.

On Page_Load Event. The path is parsed and the link is added.

<<< CODE >>>

Dim ctl1 As Control = ctl.Page.FindControl("CSS")

Dim gc As HtmlGenericControl

If Not ctl1 Is Nothing Then

gc = New HtmlGenericControl("LINK")

gc.Attributes("rel") = "stylesheet"

gc.Attributes("type") = "text/css"

gc.Attributes("href") = ctl.ResolveUrl(s)

ctl1.Controls.Add(gc)

End If

<<< END CODE >>>

The problem is with 4.3 (all previous versions including 4.0.3 do NOT have this problem).

This formatted link tag is correct.

Note that Vehicle_m.css has been added, and the closing tag </LINK> is present.

<<< CODE >>>

<<< END CODE >>>

This formatted link tag is NOT correct.

Note that Vehicle_m.css has NOT been added, and the closing tag </LINK> is NOT present.

<<< CODE >>>

My Website > Inventory ( DNN 4.3.0 )

<<< END CODE >>>

By comparing between 3.3 and 4.3 you can also see how the META tag is also malformed.

The offending code appears to be with how these tags are parsed. By comparing between 3.3 and 4.3 the Default.aspx.vb, this appears to be handled differently.

This has been logged.

Re: Malformed "LINK" Tag in 4.3.0

Interestingly, if you look at Default.aspx (not ViewSource) but the code we ship, you will see that in 4.3 there are no <LINK> tags at all. This is because the core has been changed to use the new HtmlLink Server controls that are found in .NET 2. The .NET Rendering engine, recognises that the <LINK> tag has no contained content so it uses the shorhand <LINK /> instead of <LINK></LINK>. Thus the tag is not malformed.

Similarly the <META> tags are defined using HtmlMeta server controls and rendered as <META /> rather than <META> . This is valid XHtml.

The issue here is that we removed the named placeholder <asp:placeholder id="CSS" runat="server"></asp:placeholder>, that you relied on in your code, so if that is put back your code (and others that relied on that placeholder would continue to work)

Re: Malformed "LINK" Tag in 4.3.0

I have made the change and the fix will be in the next point release. In the interim, you should be able to make it work by adding

<asp:placeholder id="CSS" runat="server"></asp:placeholder>

just before this

<style id="StylePlaceholder" runat="server"></style>

in Default.aspx

Re: Malformed "LINK" Tag in 4.3.0

Hi all,

Robert discussed also an issue with the meta tags but that does not seem to be solved in 4.3.2? I get the following meta part. As you can see, there zre no correct closing tags (/).

Any idea what goes wrong and how to solve that one?

Regards,

Erik
