Hi. I have implemented the custom ComboBox column as described in the FAQ which accepts a delegate to notify subscribers of "selected index changed" events. I have also implemented the TextBox which fires the CheckEnable event during repaints to set it's enabled/disabled status.
My problem is that when the user selects a new value in the ComboBox I need the TextBoxes to set their enabled/disabled state immediately according to the selection in the ComboBox. At the moment I have got them to do this when focus moves away from the ComboBox, but this is not quite the behaviour I was after.
I have tried invalidating the DataGrid to force a repaint but this does not work. I have also tried reading the value of the ComboBox during the CheckEnabled event handler but this simultaneously affects ALL TextBoxes in the DataGrid. Any other suggestions?
Also, can anyone recommend a book that goes into the kind of detail required to do this kind of work? I haven't seen anything even remotely as detailed as the excellent FAQ on this site.
Thanks
Kevin Hector
