I have a treeview with a Root, a Contact Type, and a Contact. Like MSN
Messenger.
Is there a way that I can say something like
if treenode.tag is classContact then
string Surname = treenode.tag.surname
And somehow, each time, I create the node, I can assign the object of that
classContact to that node ?
I think the 'Tag' part of the TreeNode would be used, but not sure how...

Thanks.
I'm looking to assign a class object that I have created, to my treenode
though...
Something like Treeview.SelectedNode.Tag = myObject..
And then later, I'd like to be able to access this objects properties via
the treenode.tag. Is this possible ?

Yes,
myObjectType myObject = new myObjectType( ...);
....
treeView.SelectedNode.Tag = myObject;
....
((myObjectType)treeView.SelectedNode.Tag).MyObject Property = newValue;

Right. That code sample does it with a DataRow. You could
just as easily do it with your class instead.

Hi Craig,
Your Tag contains a number (System.Int32) and trying to cast it to classContact will then fail.
Are all your tags classContact? Or are some of them different data types.
object o = tvMaster.SelectedNode.Tag
if(o is classContact)
{
classContact c = (classContact)o;
MessageBox.Show(c.Title);
}
