# onDock and onUndock Events

These events call user-defined handlers (if there are any) and pass the following parameter:

- itemId - the id of an item.

        dhxLayout.attachEvent("onDock", function(itemId){});
        dhxLayout.attachEvent("onUnDock", function(itemId){});

For example, let's attach an event handler for “onDock” event:

        dhxLayout.attachEvent("onDock", function(a){
            alert("The item was docked");
        });

Now, when we dock a layout item “a”, we'll get the specified alert.
