Hi,
I've made a Treeview which obviously contains treeNodes. Because of the fact
I wanted to place more info in every treeNode I made a struct which contains
2 variables. A integer one (ID) and a boolean one. I have no problem at all
assigning the coorect values and placing this object in the nodes tag. My
problem is retrieving the information stored :( How is this done ??? I have
made a method GetID in my struct but I can't seem to call it, and honestly I
wouldn't even know how to call it...
I can place some code if it's needed...
 
Since the Tag property returns an Object you won't see your custom method on
it, however you can cast this to your known type to access the custom
fields/methods etc e.g.

[C#]
CustomStruct cs = (CustomStruct)Node.Tag;
int myid = cs.GetID();
