Control's Tag Property memory usage & perofmance ?

Question

Hi All,

I have a collection of objects , which I am binding to a control , lets say TreeView ,  Now if I set to Tag property of TreeviewItem to object of that collection ,  then would that create a new object in memory and assign to Tag property of TreeViewitem or just create a reference to the Collection of Objects ?

I want to set the Tag property but not sue how much impact it will have on memory usage & performance ?

Thanks for you support.

Answer 1

Since you say "object", I assume the items in the collection are of a reference type. In that case, no new objects will be created.

Answer 2

Yes, its collection of my custom objects.

So its safe to assign Tag property of control to corresponding object.

Thanks.

Answer 3

Yes it is. You will have only one instance and both of the references (including Tag) will point to same memory in managed heap.
