I want to have some LinkButtons to download files, and on click of those I'd like to update the viewcount of the document.

So that part I can do...(quite nice with fluent)

How do I get the download URL of the document (the embed link we get in the backend). Is it safe to just call the standard URL method, and append the extension and ?Status=Master or is there a better way.

**EDIT**
Ok, so turns out the updating viewcount fails when I try it as a user not logged in...?

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.UnauthorizedAccessException: You are not authorized to 'Modify library and manage documents' ('Document').

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically MACHINE\ASPNET on IIS 5 or Network Service on IIS 6 and IIS 7, and the configured application pool identity on IIS 7.5) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.

To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

Hi Steve,

The code fails, because you cannot make modifications to an object with the api if the current user ( which in your case is anonymous ) is not granted with modify permissions.
You can use Manager.Provider.SuppressSecurityChecks = true; in your code to allow SaveChanges to be processed then set SuppressSecurityChecks back to false which is its initial state.

Best wishes,
