Changing Location of Toolstrips at startup

Question

Hello everybody,

i have a wierd error in my code. The thing i want to do is, when i close and open the program, i want to see the toolstrips at their last locations. 

this method load coordinates of two toolstrip from an xml file into a datatable,  then i hold the values in coordinate as point type. And then, i want to assign the coordinate values to location of toolstrips, but it does not work correct :S

        public void LoadToolstripCoordinates()

        {

            int i;

            Point coordinates = new Point();

            DataTable dTable = new DataTable();

            dTable = ReadLogFromXml();

            if (dTable != null)

            {   

                for (i = 0; i < dTable.Rows.Count; i++)

                {

                    coordinates.X = Convert.ToInt32(dTable.Rows[i][1]);

                    coordinates.Y = Convert.ToInt32(dTable.Rows[i][2]);

                    if (loading == 0)

                    {

//here code does not work correct

                        if (i == 0) this.toolStrip1.Location = new System.Drawing.Point(coordinates.X,coordinates.Y);

                        if (i == 1) this.toolStrip2.Location = new System.Drawing.Point(coordinates.X,coordinates.Y);

                    }

                }

                loading=1;

            }

        }

this.toolStrip1.Location has x and y values,when i debug my code, i saw that  x value changes but y value does not change. i couldn't understand the problem, if u have any idea, please inform me
