this is my code:

        private void getData(string selectCommand)
    {
        string connectionString = @"Server=localhost;User=SYSDBA;Password=masterkey;Database=C:\data\test.fdb";

        dataAdapter = new FbDataAdapter(selectCommand, connectionString);
        DataTable data = new DataTable();
        dataAdapter.Fill(data);
        bindingSource.DataSource = data;
    }

    private void button1_Click(object sender, EventArgs e)
    {
        getData(dataAdapter.SelectCommand.CommandText);
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        dataGridView1.DataSource = bindingSource;
        getData("SELECT * FROM cities");
    }

after reload data on button1 click, cell selection jumps on first column and scrollbars is reset. How to save position of DataGridView?
