    Here are the steps you need to undertake to disable the editor for a certain field when some custom conditions are met:

    1. subscribe to the ItemDataBound handler of the grid
    2. check whether the currently bound item is in edit mode
    3. retrieve the value for the edited field which will be used as a flag for enabling/disabling the column editor
    4. if the value matches the condition, disable the editor field (you can get reference to it through the auto-generated column editor)

    In the example we are enclosing, the editor for the ContactTitle will be disabled when you edit the first grid row. Note that you can hide completely the editor when setting its Visible property to false.
