C# 从其他usercontrol调用Update GridControl时不显示更改

我已经创建了一个方法来更新我的GridControl。对于我的另一个GridControl，我使用相同的方法/构造函数结构，并以相同的方式调用它，它可以工作。当我单击与update方法在同一类中的按钮时，网格中的数据被更新。但是当我从另一个usercontrol调用此方法updateGridControl时，GridControl不会发生任何变化。当我从另一个usercontrol/类调用网格时，如何更改我的代码以使该方法也更新网格

这是对方法的调用：

incidentCategorySearchControl.Instance.updateGridControl(); // update doesn't work 

incidentCategorySearchControl.cs

 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);

        bindingSource1.DataSource = reinvenT_QualityDataSet1;
    }

    public void updateGridControl()
    {
        incIncidentCategoryTableAdapter1.Fill(reinvenT_QualityDataSet1.IncIncidentCategory);
    }

    /// <summary>

    /// </summary>

    /// <param name="pt"></param>

    public void DoRowDoubleClick(GridView view, Point pt)
    {

        GridHitInfo info = view.CalcHitInfo(pt);

        if (info.InRow || info.InRowCell)
        {
            try
            {
                string colCaption = info.Column == null ? "N/A" : info.Column.GetCaption();
                Form1 myform = (Form1)this.categoryGridControl.FindForm();
                int id = Convert.ToInt32(view.GetRowCellValue(info.RowHandle, "IncIncidentCategory"));
                string description=view.GetRowCellValue(info.RowHandle,"IncIncidentCatDescription").ToString();

                IncidentCategory incidentCategoryEditTarget = new IncidentCategory(id, description);
                incidentCategoryChange.Instance.TextBoxCategory = incidentCategoryEditTarget._categoryId.ToString();
                incidentCategoryChange.Instance.TextBoxCategoryDesc = incidentCategoryEditTarget._description;

                XtraTabPage xtraTabPage = myform.xtraTabControl1.TabPages[3];
                xtraTabPage.PageVisible = true;
                myform.xtraTabControl1.SelectedTabPage = xtraTabPage;

            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

    }

    /// <summary>
    /// CategoryGridControl double click event
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>

    private void categoryGridControl_DoubleClick(object sender, EventArgs e)
    {
        GridView view = (GridView)categoryGridControl.MainView;

        Point pt = view.GridControl.PointToClient(Control.MousePosition);

        DoRowDoubleClick(view, pt);
    }


    private void closeButton_Click(object sender, EventArgs e)
    {
        Form1 myform = (Form1)this.closeButton.FindForm();
        myform.xtraTabControl1.SelectedTabPage.PageVisible = false;

        xtraTabPage.PageVisible = true;
        myform.xtraTabControl1.SelectedTabPage = xtraTabPage;
    }

    private void simpleButton1_Click(object sender, EventArgs e)
    {
        updateGridControl();
    }            
}

什么意味着更新不起作用？是否设置了断点？你有例外吗？结果不是预期的吗？若通过其他方式调用updateGridControl，结果是否正确？当从其他usercontrol调用时，你如何得出更新GridControl不显示更改的结论？当我运行我的程序并在这一行上设置断点时，更新方法中的行就到达了。我没有任何例外。GridControl显示数据库中最新值的预期结果。当我按下simpleButton1时，该方法将工作一段时间，GridControl将更新为数据库中的最新值。但是，当我从我的其他用户控件调用update方法时，值不会被更新。除非您使用多个incidentCategorySearchControls，否则您的方法应该有效。@Sinatr非常感谢这就是问题所在，另一个仍然隐藏在我的窗体上，问题已解决。
