I have a VS2005 solution that used DocumentX 5. I upgraded the soution to VS2008, and installed DocumentX 2008 (first uninstalling the old version). However, the "Edit Documentation" button is always disabled, so I cannot edit the document.

It has been some time since I last updated the documentation, so I might just have forgotten something, but I can['t find anything in the help system.

Thanks

Akash

 Some more info: if I open a different solution (one created in VS2008 that doesn't already contain dxp/dxc files), the "Edit Documentation" button works...

The edit documentation button is ony supported with Document! X 2008 I'm afraid. I apologize for any inconvenience this problem has caused you. Please visit here for upgrade pricing: http://www.innovasys.com/purchase/pricelist.aspx?productid=4ed4550a-4c3d-46ae-be9f-9fb262717886

If you have any more questions please don't hesitate to contact us on support@innovasys.com.

 I have upgraded to Document!X 2008  - the problem I am seeing occurs after the upgrade.

I do apologize for any confusion I misread your original post. For the Edit Documentation button to be available you would need to have a Class open for edit. If however this isn't the case please report this issue to suppport@innovasys.com sending in your affected project and any related assemblies.

Once again I apologize for any earlier confusion. 

 Thanks Mike, that sorted it. I was selecting the project rather than the file...user error!
