Collapse/Expand is not working in IE if the diagram size is very big


I’m using TreeExpanderButton, expand/collapse is working fine when size of diagram is small, but when the size of diagram is very big, expand/collapse button is working in chrome and edge, but not in IE.

GoJS version - 1.7.19

Yes, Internet Explorer has smaller size limits than other desktop browsers. Nothing we can do about that.

I suppose you could zoom out some when the Diagram.documentBounds gets big, but that would be really annoying too.

Hi Walter,

Is there any workaround other than zoom out option ?

Not that I know of. You can search the web to see what other people have done.
