In case anyone looks this up in the future, the key seems to be to use something like:
UltraTreeNode node = this.treeView1.UIElement.LastElementEntered.GetContext(typeof(UltraTreeNode)) as UltraTreeNode;
Do a search for the posting

"Doubleclick on scrollbar in UltraTree" for more details.

Brian,

I ran into one snag using MouseUp and KeyDown... Using the scrollbar results in a MouseUp and my treecontrol closing. I need some way to distinguish between click on tree items, and simply using the scrollbar. I have the following code (abbreviated for clarity):
private void treeView1_MouseUp(object sender, MouseEventArgs e){ if (e.Button == MouseButtons.Left) { if (treeView1.SelectedNodes.Count == 1) { UltraTreeNode nd = treeView1.SelectedNodes[0]; ChooseNode(nd.Tag as NodeTag); // basically closes form } }} private void treeView1_KeyDown(object sender, KeyEventArgs e){if (e.KeyCode == Keys.Enter) { if (treeView1.SelectedNodes.Count == 1) { UltraTreeNode nd = treeView1.SelectedNodes[0]; ChooseNode(nd.Tag as NodeTag); } }
}

Can you suggest a work around or different approach?

Thanks,

Andrew

UltraWinTree hides the selection by default when it does not have focus. The Inbox tree control does the same thing.
Try setting HideSelection on the tree to false and see if that helps.

I tried it, but in vain. Below is the code snippet that i wrote inside BeforeEditorButtonDropDown event..,
if (uFieldTextEditor.Text != null && uFieldTextEditor.Text.Length > 0)
{
ultraTree1.GetNodeByKey(uFieldTextEditor.Text).Selected = true;
}

Anything wrong here? The cursor was in the UltraFieldTextEditor., may be is that a reason?

Thanks,.

Thanks. That's the way I started to implement it. Nice to know I'm on the right path.
