some suggestion:

I hope  Hide,Unhide  functions  can  finished  by  grid.DoAction(...),because DoAction can undo and redo!

            thank you!

Re: some suggestion:

OK. Before the next version which contains this changes get released, add the code below into your project, these classes will perform the do/undo/redo actions:

	#region Hide/Unhide Actions
	public abstract class RangeOperationAction : RGAction
	{
		public ReoGridControl Grid { get; set; }
		public ReoGridRange Range { get; set; }

		public RangeOperationAction(ReoGridControl grid, ReoGridRange range)
		{
			this.Grid = grid;
			this.Range = range;
		}
	}

	/// <summary>
	/// Hide specified rows action
	/// </summary>
	public class HideRowsAction : RangeOperationAction
	{
		public HideRowsAction(ReoGridControl grid, int row, int count)
			: base(grid, new ReoGridRange(row, 0, count, -1)) { }

		public override void Do()
		{
			base.Grid.HideRows(base.Range.Row, base.Range.Rows);
		}

		public override void Undo()
		{
			base.Grid.ShowRows(base.Range.Row, base.Range.Rows);
		}

		public override string GetName() { return "Hide Rows"; }
	}

	/// <summary>
	/// Unhide specified rows action
	/// </summary>
	public class UnhideRowsAction : RangeOperationAction
	{
		public UnhideRowsAction(ReoGridControl grid, int row, int count)
			: base(grid, new ReoGridRange(row, 0, count, -1)) { }

		public override void Do()
		{
			base.Grid.ShowRows(base.Range.Row, base.Range.Rows);
		}

		public override void Undo()
		{
			base.Grid.HideRows(base.Range.Row, base.Range.Rows);
		}

		public override string GetName() { return "Unhide Rows"; }
	}

	/// <summary>
	/// Hide specified columns action
	/// </summary>
	public class HideColumnsAction : RangeOperationAction
	{
		public HideColumnsAction(ReoGridControl grid, int row, int count)
			: base(grid, new ReoGridRange(row, 0, count, -1)) { }

		public override void Do()
		{
			base.Grid.HideColumns(base.Range.Row, base.Range.Rows);
		}

		public override void Undo()
		{
			base.Grid.ShowColumns(base.Range.Row, base.Range.Rows);
		}

		public override string GetName() { return "Hide Columns"; }
	}

	/// <summary>
	/// Unhide specified columns action
	/// </summary>
	public class UnhideColumnsAction : RangeOperationAction
	{
		public UnhideColumnsAction(ReoGridControl grid, int row, int count)
			: base(grid, new ReoGridRange(row, 0, count, -1)) { }

		public override void Do()
		{
			base.Grid.ShowColumns(base.Range.Row, base.Range.Rows);
		}

		public override void Undo()
		{
			base.Grid.HideColumns(base.Range.Row, base.Range.Rows);
		}

		public override string GetName() { return "Unhide Columns"; }
	}
	#endregion // Hide/Unhide Actions

Usage:

grid.DoAction(new HideRowsAction(this.grid, grid.SelectionRange.Row, grid.SelectionRange.Rows));
grid.DoAction(new UnhideRowsAction(this.grid, grid.SelectionRange.Row, grid.SelectionRange.Rows));
grid.DoAction(new HideColumnsAction(this.grid, grid.SelectionRange.Col, grid.SelectionRange.Cols));
grid.DoAction(new UnhideColumnsAction(this.grid, grid.SelectionRange.Col, grid.SelectionRange.Cols));

thanks, Jing
