DockLayoutManager Floating Window Closed event

[User (Old forums)]

#18508 |

I would like to remove floating window from DockLayoutManager in the event of Tool Window’s closed

i.e .

var window = new ToolWindow(spy, id);
window.Closed += window_Closed;

 void window_Closed(object sender, EventArgs e)
{
            ToolWindow window = (ToolWindow) sender;
             dockLayoutManager1.ToolWindows.Remove(window);  
}

 

I encountered this error when I tried to close the window : 

“Collection was modified; enumeration operation may not executeat Xceed.Utils.Collections.ListBase.Enumerator.MoveNext()\r\n   at Xceed.DockingWindows.FloatingWindow.OnFloatingWindowClosed()  
at Xceed.DockingWindows.FloatingWindow.WndProc(Message& m)………………….”

 And it happens ONLY if I try to close Floating window. It works fine for other type of tool windows.

Anyone has any idea? Any suggestion/idea would be appreciated.

We have reproduced the issue, and we are looking at this.  We will let you know when we have more information.

There is a workaround for this problem, by making the Remove() happen later : 

 void window_Closed(object sender, EventArgs e)
{
            ToolWindow window = (ToolWindow) sender;
            this.BeginInvoke( new MethodInvoker( delegate() { dockLayoutManager1.ToolWindows.Remove( window ); } ) );
}

Yep – I just encountered this issue too – used a similar solution to yours posted (just a static version)

 

        private static void GridVirtualUserControl_Closed(object sender, EventArgs e)

        {

            ToolWindow window = (ToolWindow)sender;

            window.BeginInvoke(new MethodInvoker(delegate() { window.DockLayoutManager.ToolWindows.Remove(window); }));

        }
