How to avoid doubleclick event on a datagrid scrollbars?

Question

Hello.
I've a datagrid.
I need a doubleclick event cliccking on a data grid row.
I've enabled the doubleclick event. It works fine, when the user doubleclicks on a row, an event happens! In my case I open a modal window. Great!
Now the problem:
The problem arises when the user clicks in a short time on a data grid scroll bar (both horizontal or vertical). In this case a double click event is dispatched.
But his intenton is just to scroll the grid, no more.
Please, notice that the dobule click on a scrollbar is a well-known action that can be performed in all the applications and operating systems.
I neet the "double click" event just on a data grid rows and not on its scrollbars. Cliccking twice or more on the scrollbar I just want to scroll the grid. How can avoid to dispatch an event?
Thank you

I was returning today to add something about custom item renderers but you beat me to it, Pbesi.   I have a custom gridItemRenderer which I now have to check for just as you demonstrated above.  What I don't understand is why I can't just do this:
if( event.target is IGridItemRenderer )  //Should be true for both default and custom
My custom renderer implements the IGridItemRenderer interface, but when I double click one in the grid, the event.target is not myCustomGridItemRenderer, it is GridLayer.  So what I have to do is this:
if( (event.target is IGridItemRenderer) || (event.target is GridLayer) )
I presume this would work for all custom gridItemRenderers, but I only have one, so I haven't tested this.  Any idea why GridLayer is the type of the event target?  My custom renderer is very simple.  It just renders Booleans as "Yes/No" rather than "True/False"
