Modified Items list of your sandbox. This action is
also available when browsing content within a sandbox (user or
Staging).
Navigate to the Sandbox view of the web project you want to work
with.
Use one of the following methods to locate the content item you
want to preview:
In your user sandbox (My Sandbox),
click to expand
the Modified Items list.
In your user sandbox (My Sandbox),
click to expand
the Web Forms list. Click Browse
Content to display a list of all content items within
the web project that were generated from the associated web
form.
Click (Browse Website) for your personal sandbox in
the User Sandboxes pane. In the sandbox,
navigate the folder structure to locate the desired folder or
file.
Click (Preview File
or Preview Folder depending on your
selection). A separate browser window or a new tab opens displaying
the selected file or folder.
