Thank you for answers..

Hello,

With the help of DrawFilter you could draw only within the region of the component, so we don’t have control over outside bounds of the control.

Please let me know if you have any further questions

As shown on the attached image, is it possible to put a badge mark(the small number mark on the right top corner of the icon) like this image, showing outside of the icon area or button area?

Hello,

What expression ? Can you show me how this should looks and behave ?

I am waiting for your feedback.

Thank you for answers and samples.

Can I place the expression on the outer-range area?
