I have a Product Backlog Item (PBI) in TFS, which has multiple Sprint Backlog Tasks (SBTs) under it in a grid.
How can I modify the title of the items in that grid without opening each one individually in the preview or otherwise?
It is possible because when selecting a WorkItem, in the half screen on the bottom, you will have its details, and thus can change it. After you re done, you will be able to save all in one Ctrl-S
Better way :
I have done that by exporting result of query in MS Excel, modifying multiple columns and rows rapidly; then Publish the whole by one click.
For Visual Studio 2010, 2013, the following will work:
You can bulk edit in Team Web Access 2010. Opening the query in Excel works better for bulk-editing the titles, but if you're going to change, say, Area Path, TWA provides expandable/collapseable nodes in the hierarchy, while Excel simply gives you a drop-down menu of values.
