Unfortunately, there is no easy way to do this if you want to include columns that are not K2-specific.  The source code for the OOB worklist is available and can be tweaked to tie in to your business data, in the past we have created our own custom worklists that use smartobjects to tie business data with K2 data in one call, but your workflow processes have to be designed with this in mind.  That is, there must be a way to join your business data with K2 task data - you can rely on folio or put some unique identifier as a data field in each activity, for example.

I hope this helps, I'm sure it wasn't exactly the answer you were looking for.

thanks for the quick response.

There is some code for the K2 worklist webpart on the Blackmarket. Maybe you can use this and modify to your needs.

Where can I get the OOB worklist source code?

Vernon supplied the link, it is here:

Do you know if this webpart works in the VS2010 web part manager (and not in Sharepoint)?

Sorry Peter, I never used it directly but rather took some ideas from it for my own custom web part

Jay,

Check out our blog, We extended the management worklist webpart and added custom functionality. This might give you an idea.

Hi,

The link http://www.k2underground.com/groups/k2_worklist_web_part/default.aspx provided for custom worklist webpart is for K2 Blackpoint. Where can I get the same for K2 blackpearl.
