On a form I have a TreeView and navigationable TextBoxes. I have sparse populated the TreeView as the no. of node can go high, now if I use the TreeView for navigation then alls well.

If I navigate using the toolbar for the form, though the TV will highlight the right records if populated (by user interaction) but for the none populated nodes the TV is confused.

Any logic to make a sparse TV to populate on record movement rather than clicking on the pluses and minuses

Thanks in advance
