I have done this before many time but somehow I am missing some little step that it does not work.
Here is how I do it:
I open Form Control Toolbar.
I right-mouse click in the Grid and click on Edit. The Grid is now selected
I click on the checkbox in the Form Control Toolbar.
Then I click on the header of the column of the grid where I want to set this check box.
But it does not happen. What am I missing?
