I've created several user controls (.ascx files). &nbsp;I then created a CUSTOM folder at this location:<br />
<br />
C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\CON<wbr />TROLTEMPLA<wbr />TES\<br />
<br />
&nbsp;I placed the User Controls in the CUSTOM folder. &nbsp;I am trying to reference the controls from my Master Page like this:<br />
<br />
&lt;%@ Register TagPrefix=&quot;uc&quot; TagName=&quot;HeaderControl&quot; src=&quot;/_controltemplates/CU<wbr />STOM/Heade<wbr />r.ascx&quot; %&gt;<br />
<br />
I am using SharePoint Designer to modify the Master Page. &nbsp;It says it cannot find the files referenced. &nbsp;I have restarted the Site and restarted IIS. &nbsp;Not sure why it isnt found. &nbsp;<br />
<br />
Thanks for any help provided....
