TWebDBGrid - how to find column clicked?

I have a non-editable TWebDBGrid, I want to know which column was clicked in the OnClick event.
How can I find the column info for the column that was clicked? Is there a property to check? Or perhaps another event prior to OnClick?

Thanks.

I see OnClickCell was not exposed at design-time. But it is available, so you can assign it at runtime. We will ensure OnClickCell is exposed at design-time in the next update.
