After I populate and expand all the nodes in the TreeView the focus is at the bottom of the Treeview. But how do I set the focus on the top root node of the Treeview after expanding all the nodes? Please Help.
Thanks in advance.

Tag, please. WPF, Forms, ASP.NET?

I added a tag for you in your comment. Always do it yourself. You're interested the most, so the right expert would open your page.

"Focus" is a wrong term. Nodes do not have focus (a control has). A node can only be selected or not. So, look at the methods related to selection. For example, use System.Windows.Forms.TreeView.SelectedNode read/write property.

This is for Forms. Do this simple exercise by yourself for other UI libraries:
http://msdn.microsoft.com/en-us/library/system.windows.forms.treeview.aspx[^],
http://msdn.microsoft.com/en-us/library/system.windows.controls.treeview.aspx[^],
http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.treeview.aspx[^].

Which one of those TreeView controls do you need?

Why didn't you tag the UI library you want to use? Always do it! We cannot read your mind.
If you did, you would get exact answer.

Thank you, Monjurul, but... nothing special, only a result of not tagging a question properly.

Thanks for correcting me. Sorry I'm new to this forum. I am looking for the Windows forms Treeview.

You still did not tag it. OK, for this UI library I already answered -- use TreeView.SelectedNode.
