Hi,

I'd like to draw a thick border on certain cells when they are hovered with the mouse or clicked on. How could I achieve this?

Thanks,

Tom

TreeView/ListView Replacement sample has a some code that colours node under mouse cursor.
You can use the code from TreeView/ListView Replacement sample and modify/improve it for your needs.

Well, as you said, this colors a node but I want to color an individual cell from a node only?

I think it can be implemented as following:
1. You can create a special node (HoverNode for example) class and in the FlyGrid.MouseMove handler specify hovered node and cell to this node.
2. Changing of HoverNode.HoveredNode and HoverNode.HoveredCell (these properties should be static) invalidate old value of these properties and new values specified.
3. In the painting procedure of Hovernode color of cell specified by HoverNode.HoveredNode and HoverNode.HoveredCell properties will be colored.
