I would like to use a rendering control which has reference to two different cells.
If I override the the ControlContainerEditor class, the RendererValue property set the value from one cell.
If I would like to represent for example an interval, set on 2 different column, is there any possiblity to have a reference to the value from an other column cell?
The ControlContainerEditor is designed for a single value. So what I would do is create an unbound column in your grid that contains both pieces of information you need. You could create the column with a DataType that is some object that has two properties on it. Then assign the ControlContainerEditor to that unbound column.
This might be a bit tricky, especially if you need to make the column editable, because the object you use will need to raise notifications like INotifyPropertyChanged in order to work correctly.
