Yeah that should be possible by doing some additional coding on the click event to check wheter this item can be opened or not. Stopping event propagation might work for this. Im not sure if you can show another icon/image for the “disabled” rows, but propably, there is.

Hey Arjan,
Is there a way to disable the disclosureopen/closeicon for partticular rows of an ADG programmatically ??

Hi Alison,

Yeah that’s possible. Just add an event listener to your Tree component on the click event:

click=”handleClick(event)”

And add the following function to your script:

private function handleClick(event:MouseEvent):void
{
tree.expandItem( tree.selectedItem, !tree.isItemOpen( tree.selectedItem ) );
}

This will open the clicked item if it’s closed and close it if it’s open.

Good luck!

Is it possible to the header text works as a link to expand the node?
In this example, only the tree expands when we clik on the minus and plus icon. I wanna clik en the header (node1… node6) and expand the tree.

Is it possible?

Thanks
