I have a gridview with horizontally merged cells. Its an overview of weekly tasks.
I have 5 columns representing monday-friday in there, and I want to be able to copy values from another item to a mergedcell.
Basically, If the same person is responsible for a task on a monday, and another task the whole week, I want to be able to copy that person to a mergedcell, and make its value apply to all underlying cells.
I'd like to be able to do this with the actual underlying collectionview, but for now I'm using a workaround with the visual tree. My only issue is that I can find a certain row/column index in the mergedcells, which reflects the virtualized position, i.e. where it is on the screen, which includes group headers.
Is there a way I can get to the collection of all items currently visible myself? including group headers? So I can find the dataitem?
