Windows forms treeview select node in code

Setting TreeeView. HideSelection to false will keep the selected node highlighted when treeview does not have the focus, it's just may not be so apparent because a different colors are used to highlight a node when the TreeView has and doesn't have the focus.

You can manually set focus to TreeeView when you click on a button, if that's an acceptable solution for you. Focus after you set SelectedNode. Otherwise you would have to implement your own custom drawing for the nodes which may be too much of a hustle. In case this is not helpful, and you still don't see that the node has been selected please do show the code for the button click handler.

I've entered this code and It seems like this might be working but SelectedNode is not highlighted as it is when you do a mouse click on the Node. Mike, Ive tested with the code that you have provided but it does nothing. I can click on a node and it is highlighted. I've implemented a button that when pressed runs the code that you provided and tries to force another node to be selected but nothing changes.

I get no errors and I get no changes in the TreeView. Thanks Vladimir. I do see now that the color is much the same as Windows Explorer. I never noticed it before. I never could force a node to be selected by clicking on a button but I've modified my code now to get around that part. This is still a "bug" in Windows. NET 4. The TreeView.

Got my mistake.. Thanks a lot — user Yes, constructor is not quite the same as Form Load. Something I learned was that when you select the node programatically and it doesn't appear selected blue it's possible due to the treeview not being the active control.
