I believe the better solution is to customize DreamWeaver instead of Prado.
You just need to do two steps:
1. Edit the file \Program Files\Macromedia\Dreamweaver 8\Configuration\DocumentTypes\MMDocumentTypes.xml:Line 3
<documenttype id="HTML" internaltype="HTML"
winfileextension="html,htm,shtml,shtm,stm,tpl,lasso,xhtml"
macfileextension="html,htm,shtml,shtm,tpl,lasso,xhtml,ssi"
file="Default.html"
writebyteordermark="false">
by adding
page to the
winfileextension and
macfileextension so it becomes:
<documenttype id="HTML" internaltype="HTML"
winfileextension="html,htm,shtml,shtm,stm,tpl,lasso,xhtml,page"
macfileextension="html,htm,shtml,shtm,tpl,lasso,xhtml,ssi,page"
file="Default.html"
writebyteordermark="false">
2. In DreamWeaver goto Edit -> Preferences -> File Types/Editors and add
.page to the list of extensions on the left then choose an editor by clicking on the + sign on the right and browsing to the Dreamweaver.exe and select it.
Once you're done with this, Dreamweaver will treat your .page files like HTML pages and give you code completion for PRADO tags.
