I have a listbox with 30 rows , and one column defined as checkboxes.
I want exactly one item to be checked.
With no code, the user can select or unselect as many items as they wish.
In the cell click event I tried to record the clicked cell, then set all the check states to false, then set the check state of the clicked row to be true.
This does not work.
I added invalidate and refresh in case it was simply not repainting, this also didnt do what I needed.
I tried trapping mouse down and mouse up but havent made much progress there.
Has anyone used a listbox in this way before and can give me a hint to an elegant way to handle this?
