I am looking for some
way to support tooltip per cell. Your product (DHTMLxTreeGrid) does support
tooltip out of the box for treetable but defaults to the value of the cell. I
would like for it to show useful help information. Do let me know how this is
possible.
In case of dhtmlxGrid ( dhtmlxTreeGrid ) tooltips are based on cell types.
All predefined cell uses inner text value as tooltips. You can create a
new excell, or override logic of existing excell to organize tooltips
