Hi Stoyo,

How can I set the internal height of the TreeViewNode so the vertical scrollbar properly reflects the contents.

As you can see in the image, the scrollable area is quite a bit larger than the contents (same issue with Table nodes - would like to stop the table scrolling if no more rows are available to be scrolled into view).

Additionally, the Expandable property is ignored e.g. I can't get the + to display on a TreeViewNode.

Thanks Stoyo, new dll work as expected.

I'm trying to change the cursor when the mouse is over a TreeViewItem that is underlined.

The only place I can see this being handled is MouseMove, but the event is not called the way I expect at all.

This is my starting point

        private void diagramView_MouseMove(object sender, MouseEventArgs e)
        {
            PointF point = diagramView.ClientToDoc(e.Location);
            DiagramNode diagramNode = diagram.GetNodeAt(point);
            if (diagramNode is TreeViewNode)
            {
                TreeViewNode node = (TreeViewNode) diagramNode;
                TreeViewItem item = node.ItemFromPoint(e.Location);
                if (item != null)
                {
                    TableField tableField = item.Tag as TableField;
                    if (tableField.ForeignTable != null)
                        Cursor.Current = Cursors.Hand;
                }

            }
        }
 

When the MouseMove event is raised is unpredictable, basically I could move the mouse all over the TreeViewNode, and it never gets to breakpoint on 'TreeViewNode node = ...'

Try setting diagramView.DrawLinkCursor.

I hope that helps,
Stoyan

where can i find the new dll ?

yes.. still i didn't have the scroll bar. my treelayout is very big each node has atleast 5 child up to 5 levels...

Thanks for your reply. But my requirement is to expand only my current node not child and sub child node.

mmmmmm....when i click the expand (+) button i want to expand only that node not the subchild

Stoyan thanks a lot... your so great
