Placing and sticking control around a rectangle

Question

I'm developing a small snipping tool, which works but I just can't get my head around how I place two toolstrip controls around selected snip region (rectangle). I refresh the toolstrip location on mouse-up event, which handles the movements for both toolstrips like this.

//The two toolstrips that I have
//rcSelect is the selected rectangle

toolStrip1.Visible = true;
toolStrip2.Visible = true;

//Tool Strip One
int toolstripY = (rcSelect.Y + rcSelect.Height) - toolStrip1.Height;
int toolstripX = rcSelect.Width + rcSelect.X + 5;

if (toolstripX + toolStrip1.Width >= this.Width)
{
    toolstripX = rcSelect.X - toolStrip1.Width - 5;
}

if (rcSelect.Width + toolStrip1.Width >= this.Width)
{
    toolstripX = rcSelect.Width - toolStrip1.Width;
}

if (toolstripY + toolStrip1.Height >= this.Height)
{
    toolstripY = rcSelect.Y;
}

if (rcSelect.Height + toolStrip1.Height >= this.Height)
{
    toolstripY = rcSelect.Height;
}

if (toolStrip1.Location.Y + toolStrip1.Height >= this.Height)
{
    toolstripY = rcSelect.Y - toolStrip1.Height - 5;
}


//Tool Strip Two

int toolstrip2Y = rcSelect.Y + rcSelect.Height + 5;
int toolstrip2X = rcSelect.X + (rcSelect.Width - toolStrip2.Width);


if (toolstrip2Y + toolStrip2.Height >= this.Height)
{
    toolstrip2Y = rcSelect.Y - toolStrip2.Height - 5;
}

if (rcSelect.Height + toolStrip2.Height >= this.Height)
{
    toolstrip2Y = rcSelect.Height - toolStrip2.Height;
}

if (toolstrip2X + toolStrip2.Width >= this.Width)
{
    toolstrip2X = rcSelect.X;
}

if (rcSelect.Width + toolStrip2.Width >= this.Width)
{
    toolstrip2X = rcSelect.Width;
}

if (toolStrip2.Location.X + toolStrip2.Width >= this.Width)
{
    toolstrip2X = rcSelect.X - toolStrip2.Width - 5;
}


//Try to Insure visbility yet again

if (toolStrip1.Location.Y + toolStrip1.Height >= this.Height)
{
    int offsetY = (toolStrip1.Location.Y + toolStrip1.Height) - this.Height;
    toolstripY = toolStrip1.Location.Y - offsetY;
}


if (toolStrip2.Location.X + toolStrip2.Width >= this.Width)
{
    int offsetX = (toolStrip2.Location.X + toolStrip2.Width) - this.Width;
    toolstrip2X = toolStrip2.Location.X - offsetX;
}


if (toolstrip2X < 0)
{
    toolstrip2X = 0;
}

if (toolstrip2Y < 0)
{
    toolstrip2Y = 0;
}

if (toolstripX < 0)
{
    toolstripX = 0;
}

if (toolstripY < 0)
{
    toolstripY = 0;
}


toolStrip1.Location = new Point(toolstripX, toolstripY);
toolStrip2.Location = new Point(toolstrip2X, toolstrip2Y);

This is how it looks at start.

And this is how it looks when i resize and move that rectangle

I don't know which ToolStrip is vertical or horizontal, but you can try it this way:

protected override void OnMouseDown(MouseEventArgs e) {
  base.OnMouseDown(e);
  rcSelect = new Rectangle(e.Location, Size.Empty);
}

protected override void OnMouseUp(MouseEventArgs e) {
  base.OnMouseUp(e);
  int rcLeft = Math.Min(e.X, rcSelect.X);
  int rcTop = Math.Min(e.Y, rcSelect.Y);
  int rcWidth = Math.Max(e.X, rcSelect.Left) - Math.Min(e.X, rcSelect.Left);
  int rcHeight = Math.Max(e.Y, rcSelect.Top) - Math.Min(e.Y, rcSelect.Top);
  rcSelect = new Rectangle(new Point(rcLeft, rcTop), new Size(rcWidth, rcHeight));

  toolStrip1.Location = new Point(
    Math.Max(0, 
      Math.Min(this.ClientSize.Width - toolStrip1.Width,
               rcSelect.Right - toolStrip1.Width)
    ),
    rcSelect.Bottom > this.ClientSize.Height ?
      rcSelect.Top - toolStrip1.Height :
      rcSelect.Bottom
  );

  toolStrip2.Location = new Point(
    rcSelect.Right > this.ClientSize.Width ?
      rcSelect.Left - toolStrip2.Width :
      rcSelect.Right,
    Math.Max(0, 
      Math.Min(this.ClientSize.Height - toolStrip2.Height,
               rcSelect.Bottom - toolStrip2.Height)
    )
  );
}
