Question

markerValue and tag

I noticed that you can put tag and markerValue properties on a button but I was unable to find out what are those used for. Do you know what's their purpose?

markerValue  - for automated testing,

tag - can be used in the event handler. for example, assign one method to several buttons and, using this property, understand which element caused the event

Grigoriy,

Ok, thank you for the explanation.
