Check/Uncheck grouped rows in Janus GridEX

Question

I use Janus.Windows.GridEX.GridEX grid and also have a column which is ActAsSelector.

When the rows are grouped in a group, I want to be able to check/uncheck all of them. Do you know build-in functionality or easy way to achieve the goal?

Answer 2

Just set the UseHeaderSelector property of the selector column to True.
