usercontrol中的GridControl从其他usercontrol刷新

Question

我在更改数据库后尝试刷新GridControl。更改将保存在数据库中，但GridControl不会显示新数据。如何刷新网格并显示数据库中所做的更改？ update方法中的MessageBox是检查方法是否已执行并且MessageBox弹出以便执行。

使用GridControl的部分类

public partial class incidentCategorySearchControl : UserControl
{
    public static incidentCategorySearchControl Instance { get; set; }


    public incidentCategorySearchControl()
    {
        InitializeComponent();
        Instance = this;

        // This line of code is generated by Data Source Configuration Wizard
        incIncidentCategoryTableAdapter1.Fill(reinvenT_QualityDataSet1.IncIncidentCategory);
    }

    public void updateGridControl()
    {
        MessageBox.Show("..........." );
        //categoryGridControl.RefreshDataSource();
        incIncidentCategoryTableAdapter1.Fill(reinvenT_QualityDataSet1.IncIncidentCategory);


    }
}

调用GridControl更新方法的类的一部分：

 private void saveCategoryChangeButton_Click(object sender, EventArgs e)
    {
        if (incidentCategoryDescTextBox.Text.Trim().Length == 0)
        {
            MessageBox.Show("Opslaan mislukt controleer a.u.b. of alle verplichte velden juist zijn ingevuld");
        }
        else
        {
            try
            {

                using (SqlConnection con = new SqlConnection(SqlServerConnection.sqlConnection.ConnectionString))
                {
                    con.Open();

                    using (SqlCommand cmd = new SqlCommand("UPDATE IncIncidentCategory SET IncIncidentCatDescription = @categoryDescription WHERE IncIncidentCategory = @categoryId", con))
                    {
                        IncidentCategory incidentCategoryUpdate = new IncidentCategory(Convert.ToInt32(incidentCategoryTextBox.Text), incidentCategoryDescTextBox.Text);
                        cmd.CommandType = CommandType.Text;
                        cmd.Parameters.AddWithValue("@categoryId", incidentCategoryUpdate._categoryId);
                        cmd.Parameters.AddWithValue("@categoryDescription", incidentCategoryUpdate._description);
                        cmd.ExecuteNonQuery();
                        MessageBox.Show("Wijzigingen opgeslagen"); 

                    }
                }

                incidentTypeChange.Instance.refreshCategorySearchBox();
                incidentTypeMaintenance.Instance.refreshCategorySearchBox();
                incidentCategorySearchControl.Instance.updateGridControl(); // update doesn't work 
                //var control = new incidentCategorySearchControl();
                //control.updateDataGridView();



            }
            catch
            {
                MessageBox.Show("Voer voor beide velden geldige waarden in a.u.b.");
            }
        }
