Nadya,

You should be able to use the rightclick() as long as its the last selection you make while holding the shift or ctrl keys to make your selections. All the other selections should be made with the left click.

> I put this code in list.RightClick() event and when spent almost 1 hour trying to understand, why it doesn't work. Finally I discovered, that RightClick() loose the current selection and keeps only one item selected. Is there a way to avoid this behavior or RightClick is a bad place to put such code?
