    IsPostBack Page object’s property that determines if a Web page is being requested without data being submitted to server. IsPostBack property returns the boolean value either True or False.
    If the page is being rendered for the first time, the code calls the FillDataGrid() method.
    private void Page_Load()
    {
    if (!IsPostBack)
    {
    // Your implementation
    FillDataGrid ();
    }
    }
    Next time (during postback) FillDataGrid() method will not be called.
