I want to create a collapse button like the one on the "Manage User Fields" form, but is unable to find a way to add the collapse button (the little yellow triangle) to a cell.
Any help will be apreciated.
jut a little point, I'm not saying here that this ActiveX is the one to use in Business One. It's jut a sample, you may consider to try others also..
It's not possible to have the event in the Business One queue. I handle the event in a specific sub, when I define the Tree object as a WithEvent objects. Then in a class that handle the tree, I fired the event when the user make changes on the tree.
