Description: When we scroll the RadGridView from Top to Bottom and Bottom to Top the first record is cut off, if we click the refresh button then it will be displayed properly. 

To reproduce:
- add a RadGridView to a form
- add a RadButton to a form
- use the following code snippet:

public Form1()
        {
            InitializeComponent();

            radGridView1.MasterTemplate.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.None;
            radGridView1.EnableCustomFiltering = false;
            this.radGridView1.AutoSizeRows = true;

            radGridView1.Columns["CustomerID"].Width = 100;
            radGridView1.Columns["CompanyName"].Width = 150;
            radGridView1.Columns["ContactName"].Width = 150;
            radGridView1.Columns["Country"].Width = 100;
            radGridView1.Columns["Phone"].Width = 90;
            radGridView1.Columns["Fax"].Width = 90;

            radGridView1.Columns["Phone"].AllowFiltering = false;
            radGridView1.Columns["Fax"].AllowFiltering = false;
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            // TODO: This line of code loads data into the 'nwindDataSet.Customers' table. You can move, or remove it, as needed.
            this.customersTableAdapter.Fill(this.nwindDataSet.Customers);

        }

        private void radButton1_Click(object sender, EventArgs e)
        {
            Form1_Load(sender, e);
        }
