I am trying to initiate an inplace edit via a command handler. I have serveral grids and edit buttons, and the grid is located via an argument passed into the command via the command parameter. 

I can manually initiate editing.

I know the correct grid is being identified.

I know that there is an active cell.

I can't get it to switch into edit mode, though.

NOTE: If I first double-click a cell to go into edit mode and then hit ESCAPE, the cell shows a dashed outline. If I then execute my Command, the cell switches back into edit mode. Very strange.

=======

private void CommandBinding_Executed(object sender, ExecutedRoutedEventArgs e)
{
    RoutedCommand cmd = e.Command as RoutedCommand;

    switch (cmd.Name.ToLower())
    {

        case "edit":
            {
                XamDataGrid grid = FindCommandTargetGrid(e.Parameter);

                if (grid != null)
                {
                    grid.ExecuteCommand(DataPresenterCommands.StartEditMode);
                }
            }
            break;
    }
}
