I'm using Visual Studio Online to manage my project, it's setup as a Scrum project.
My question is, why can't I drag a work item or bug into the To Do, In Progress, or Done columns when viewing the board within a sprint?
I can drag tasks between the columns in a sprint board, but not work items or bugs.
If I go the main backlogs view and go to the board I can drag work items and bugs between columns, but in the board for a sprint this doesn't work.
It seems there is an option within the sprint board to have bugs appear on the board with tasks.
In Visual Studio Online, go to your current sprint and select the board.
Click the settings button (gear wheel in top right of screen).
Under the General section select "Working with bugs".
Here you can choose "Bugs appear on the backlogs and boards with tasks.".
This allows bugs to be dragged between columns in your sprint board.
Bugs can now be children of Product Backlog Items.
What you get is as expected. You can't drag Product Backlog or Bug on Sprint board.
You may be aware that, when dragging item on the board, from To Do column to In Progress column for example, the State for that work item is changed from To Do to In Progress as well. States on Sprint board are To Do, In Progress and Done, which are match Task's states not Product Backlog or Bug. So, you can't drag Product Backlog or Bug on Sprint board.
