Thanks for your reply. I looked at the source code of TreeVirtual. By
default the property showCellFocusIndicator is set to false. When a cell is
clicked the focus indicator is used to calculate width/height of the cell
editor. Because showCellFocusIndicator is set to false the width/height is
-4 and as a result the editor is not displayed.
After setting the property showCellFocusIndicator to true the editor is
getting displayed but it is not getting closed when mouse is clicked on
other cell. It behaves erratically.
One more question. I looked at class SimpleTreeDataModel. This class

I agree but I was looking for a feature which is demonstrated at
http://www.dhtmlx.com/docs/products/dhtmlxTreeGrid/samples/03_nodes_rows_manipulations/03_treeGrid_basic.html
