It's possible this method is not being called on public class GridToolBarContainer<TItem> : TableToolBarContainer

private protected void DetachBreakpointChanged()
{
  if (this.RootComponent == null)
    return;
  this.RootComponent.BreakpointChanged -= new Action(this.BreakpointChanged);
}

It looks like there are still some issues with the GridToolBar detaching events on dispose.

Hello,

As an update on the item, I can briefly inform you that the fix is already available in version 11.1.1. To benefit from that fix, upgrade to our latest version.

In terms of the root cause, the issue stemmed from a missing detachment of certain events associated with the Grid column menu.

I hope this information serves you well.

Regards,

In the Video I sent you guys, it looked like the Grid overall had leaks too.  Not just the column menu.
