How can I get this behavior (Excel Like or Project Grid like)? When selecting a range of cells with the mouse or keyboard: 1) Pressing any “Arrow key” clears the selections and moves to the desired cell. 2) Pressing “Enter” the current cell cycles through all the cells in the selections. Thanks.

You can probably do this by handling the CurrentCellKeyDown event. Here is a try at this.
private void gridControl1_CurrentCellKeyDown(object sender, KeyEventArgs e)
{
	GridCurrentCell cc = this.gridControl1.CurrentCell;
	if(this.gridControl1.Selections.Count > 0 
		&& this.gridControl1.Selections.Ranges.AnyRangeContains(GridRangeInfo.Cell(cc.RowIndex, cc.ColIndex)))
	{
		if(e.KeyCode == Keys.Enter)
		{
			GridRangeInfo range = this.gridControl1.Selections.Ranges.GetRangesContaining(GridRangeInfo.Cell(cc.RowIndex, cc.ColIndex))[0];
			range.ExpandRange(1, 1, this.gridControl1.RowCount, this.gridControl1.ColCount);
			int row = cc.RowIndex + 1;
			int col = cc.ColIndex;

			if(cc.RowIndex + 1 > range.Bottom)
			{
				if(cc.ColIndex < range.Right)
				{
					row = range.Top;
					col++;
				}
				else
				{
					row = range.Top;
					col = range.Left;
				}
			}
			this.gridControl1.CurrentCell.MoveTo(row, col);
			e.Handled = true;
		}
		else
		{
			if(!e.Control && !e.Shift && 
				(e.KeyCode == Keys.Up || e.KeyCode == Keys.Right
				|| e.KeyCode == Keys.Down 
				|| e.KeyCode == Keys.Left))
					this.gridControl1.Selections.Clear();
		}
	}
}
