Hello. I have a selected part changed.
private void SelectedPartsChanged(object sender, EventArgs e)
NotifyCollectionChangedEventArgs l_event = e as NotifyCollectionChangedEventArgs;
If i add a element:
l_event.Action is Add
If i remove … l_event.Action is Remove.
If i no select element, l_event.Action is Reset
Ok, for the moment, but, if i change the selected element, we have two events:
Reset, and Add. And for a little moment, part.selected is null.
But if no select any element, only reset is called.
So, i need to know when the user select a node or the void ( no element).
The reset does not work (is change, the reset is launch)
selected part = null, does not work, a little moment when change a node is null.
How could do this?
Thanks in advance
