C1FlexGrid strange behavior with unbound Boolean columns

    I have a C1FlexGrid bound to a list of objects.
    Some of the columns are in unbound mode (using GetUnboundValue and SetUnboundValue)
    Columns with DataType = Boolean raise GetUnboundValue event every time the mouse pointer hover a cell, while the normal behavior should be to raise the event when the cell needs to be displayed.

    Hi luigi giovanni,

    Sorry, we do not face the issue at our end and GetUnboundValue event does not raise every time the mouse pointer hovered over a cell.
    If you are doing something else then please let us know and modify the sample accordingly.

    Attached is my sample project.

    GetUnboundvalue event is traced to the output window, so you can see that every time the mouse pointer hovers on a checkbox the event is raised.
