Splitter: collapsed two-way binding or CollapsedChanged event

[MaklaCof]

I'm submitting a...

• Suggestion for improvement

What is the motivation or use case for changing the behavior?

• I would like to save (on server for example) in what collapsed state user leaved splitter pane.
• I would like to control collapsed state from code. Current the only option is to do it without [collapsible]="true", because there is no way I can track if user changed collapsed property in UI.

I suggest two-way binding for collapsed property.
If for some reason this is not possible, I suggest adding event CollapsedChange.

Same is done for size property as described here.

This functionality has been released on the development channel, version v2.1.0-dev.201802151013.

@gyoshev
Can I ask what was released. 2-way binding, event or both? I check documentation on DEVELOP channel but not find that information.

[gyoshev]

@MaklaCof both, because two-way binding is implemented through an event 🙂 In Angular, two-way binding is available for the property propName when there's a @Output() public propNameChange event emitter.

The event is documented in the SplitterPaneComponent API page.

When will this functionality be available on the main channel? Is there a workaround for using that functionality with the current stable release? How can I bind to the collapsed event without using a development build?

@Kevat version 2.1.0 of the package has just been released, and includes the above functionality.

@gyoshev Thank you Alex! I was able to update the package and use the new event emitter for collapsedChange.
