I believe you helped me on the right way.
Indeed, the SelectedButton Property was written in order to use it on the fly in the calling form.
But being an old man having difficult to understand event stuff, it will take me some time to implement the changes in ButtonsTemplate.

ButtonsTemplate is a compiled control dll made with enclosed code.
In the calling Form1 I want to know which button was clicked.
I try this by calling event Object_Click. But this one is never triggered.

OK, setting the colors can be done easier.
But let's concentrate on my question.
After adding control ButtonsTemplate to Form1, and when pressing on any of the buttons, I want to be notified about which button was pressed.
I tried this with the event Object_Click. It's here I am stucked
Thanks anyway for the quick reply.

The rubbish code is because after subsequent clicks on the buttons only one should be colored red and all the others should be white.
But that was not the question : in my calling Form1 I want to know which button was pressed.
