    Is there any way to implement Excel-style "Delete" key behavior for selected cells in RadGridView? I want the Delete key to clear the selected cell's contents, setting the underlying data-bound property value to null or whatever the default value of the databound type is.
    I haven't been able to find any info on whether this is possible-- somebody posted a related issue in 2010 (http://www.telerik.com/forums/cleaar-the-cell-content-at-runtime) but it does not appear to have been resolved.
    Could someone please help me implement this behavior? I'm currently trying to override the delete key in a custom KeyboardCommandProvider but none of the RadGridViewCommand options do what I want.

    Hello Aaron,

    You can achieve the desired behavior by using a custom KeyboardCommandProvider and handling the Delete key by overriding its ProvideCommandsForKey method. Here's an example:

    public override IEnumerable<ICommand> ProvideCommandsForKey(Key key)
        List<ICommand> commandsToExecute = base.ProvideCommandsForKey(key).ToList();
        if (key == Key.Delete)
            foreach (var cell in parentGrid.SelectedCells)
                var property = cell.Column.UniqueName;
                var club = cell.Item as Club;
                club.GetType().GetProperty(property).SetValue(club, null);
        return commandsToExecute;

    Would such an approach be suitable for your requirements?
