Sharepoint:SPSecurityTrimmedControl

Question

I have this in my master page.

<Sharepoint:SPSecurityTrimmedControl runat="server" Permissions="CreateSSCSite">
    <SharePoint:CssLink runat="server" Version="4"/>
</Sharepoint:SPSecurityTrimmedControl>

If the user meets the permissions then it returns:

<span>
    <link rel="stylesheet" type="text/css" href="/_layouts/1033/styles/Themable/corev4.css?rev=oiylGAjBYhJ%2Bvc6V%2B0b7wg%3D%3D"/>
</span>

How can I make it not return those infernal span tags?

Answer 1

Adding to iambriansreed's solution, you can put the comments in Literal controls around the SPSecurityTrimmedControls to prevent SPD from adding the extra rubbish. For example:

<asp:Literal runat="server" text="&lt;!-- "/><SharePoint:SPSecurityTrimmedControl PermissionsString="EditListItems" runat="server"><asp:Literal runat="server" text=" --&gt;"/>
    <link rel="stylesheet" type="text/css" href="/_layouts/1033/styles/Themable/corev4.css?rev=oiylGAjBYhJ%2Bvc6V%2B0b7wg%3D%3D"/>
<asp:Literal runat="server" text="&lt;!-- "/></SharePoint:SPSecurityTrimmedControl><asp:Literal runat="server" text=" --&gt;"/>

It's a bit annoying, but simpler than writing a new control.

If you're using SharePoint 2013's Publishing Infrastructure, the same example will look like this on an HTML master page:

<!--SPM:<asp:Literal Text="&lt;!&#45;&#45; " runat="server" />-->
<!--MS:<SharePoint:SPSecurityTrimmedControl runat="server" Permissions="CreateSSCSite">-->
<!--SPM:<asp:Literal Text=" &#45;&#45;&gt;" runat="server" />-->
    <link rel="stylesheet" type="text/css" href="/_layouts/1033/styles/Themable/corev4.css?rev=oiylGAjBYhJ%2Bvc6V%2B0b7wg%3D%3D"/>
<!--SPM:<asp:Literal Text="&lt;!&#45;&#45; " runat="server" />-->
<!--ME:</SharePoint:SPSecurityTrimmedControl>-->
<!--SPM:<asp:Literal Text=" &#45;&#45;&gt;" runat="server" />-->

Answer 2

The easiest and cleanest way to do this is wrap the control with html comments:

<!-- <Sharepoint:SPSecurityTrimmedControl runat="server" Permissions="CreateSSCSite"> -->
    <SharePoint:CssLink runat="server" Version="4"/>
<!-- </Sharepoint:SPSecurityTrimmedControl> -->

If the user meets the permissions then it returns:

<!-- <span> -->
    <link rel="stylesheet" type="text/css" href="/_layouts/1033/styles/Themable/corev4.css?rev=oiylGAjBYhJ%2Bvc6V%2B0b7wg%3D%3D"/>
<!-- </span> -->

Super simple.

Answer 3

You should be able to create your own control inheriting from Sharepoint:SPSecurityTrimmedControl and override RenderBeginTag and RenderEndTag to do nothing
