Hi David,

Thanks for your post, it was really helpful and I solved my problem.

Thanks again and regards

Damien

Hey Damien,

What you want to do is change your handler to 

Handler(sender, args)

Than you can get the active cell as args.getActiveCell().  When you were doing 

var grid = $find("GridSampleSize");,

that was finding the hierarchical grid.  to get to the activation behavior, you'd have to do grid.get_gridView().get_behaviors()...  To get the parent row of the grid that has the active cell, you can actually do sender.get_parentRow().

Hope this helps you out.

Hello Radoslav,

Sorry for my late answer, I was on holidays with no possibility to test your solution.

Thanks for your help, and for your clues, but I could not not see how reach my parent cell when the children has the focus. 

I created a JS function called "Handler", like this:

function

Handler()

{

var grid = $find("GridSampleSize");

        alert(activeCell);

}

and I have the error "null is null or not an object, but GridSampleSize exists.

And once I will have the active cell, how could I have the parent?

Thanks for your help

Sincerely,

Damien
