One of the most annoying things that I have seen from Infragistics, an otherwise brilliant company, is the fact that when any of their controls lose focus the selected item is not longer selected!

This has been so annoying for a long time for me and I have finally found the property on the control that stops it from happening.

The property name is HideSelection and by default is set to true. Setting this value to false makes the selected item in that control (implemented by all Infragistics controls I think) keep the item selected when it does not have focus.

Simple thing. Yes. Bugged me for months. Definitely.
