This usually happens when you are populating grid at Page_Load as soon as RowUpdating event gets called before that Page_Load event get's called which populates the grid with initial values. How to Avoid? Use !IsPostBack for this purpose 

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        BindGrid(); // For e.g.
    }
}
