Custom Visuals Table control with selection

Hi,

Very new to all this so please be gentle.

I want to have a table control which allows the selection of a row so that dataselected is fired.

I have look at the tutorial for barchart and, although not a table, it does implement this in the fashion I need. I therefore tried to adapt the GridNode to implement the same code in the barchart.

I have run into a few problems.

1/ The barchart implements visualTransform but does not use table for the dataViewMappings. How do I implement this for a table?

2/ How do I implement host.createSelectionIdBuilder()

Thanks
