tree tag object

[bob]

Hi.. I have a usercontrol that I'm assigning to a tag while setting up
treenodes.. I'd like to be able to get access to that userControl from
the tag on a tree double click..

tv.UserControl1 uc;
uc=new tV.UserControl1();

node.Nodes.Add("one");
node.Nodes[node.GetNodeCount(false)-1].Tag=uc;

On Double Click of a tree node I'd like to get to that UserControl I
tagged..
Anyone know if this can or how to do this? I can use gettype to see
that
the tag is my UserControl, but I can't seem to get to the UserControl
to access it's properties/functions etc... any help would be
appreciated..

Thanks , John

Hi John
Try this

MyUserControl MyTagObject = (MyUserControl)tv.Nodes[tv.CurrentNode].tag;

or

MyUserControl MyTagObject = tv.Nodes[tv.CurrentNode].tag as MyUserControl;

This will not throw an exception but return null in MyTagObject if the tag
is not of type MyUserControl.

Accessing of the Nodes in the tree is probably not correct above but you get
the idea
