Question

我有一个WPF应用程序，允许用户输入生产数据。

因此我创建了一个使用WPF Toolkit Accordion的Usercontrol。在Code背后，我创建了15个手风琴项目。每个项目都有一个Stackpanel和5-10个文本框。

将12个这些控件添加到主内容控件时，大约需要10秒钟。

这种行为的原因是什么？

    public XXXMeasurementControl(Measurement meas)
    {

        InitializeComponent();


        if (meas.ID == -2)
        {
            LineNameTextBlock.Text = "Total";
        }
        else
        {
            LineNameTextBlock.Text = meas.MeasureDate.ToString("HH:mm") + " - " + meas.MeasureDate.AddHours(1).ToString("HH:mm");
        }



        this.cells = meas.MainCells;
        this.meas = meas;


        Binding b = new Binding();
        Remark.DataContext = Meas;
        b.Mode = BindingMode.TwoWay;
        b.Path = new PropertyPath("Remark");
        BindingOperations.SetBinding(Remark, TextBox.TextProperty, b);

        //Create Cells Start

        foreach (Cell c in cells)
        {
            //Creating Textboxes & Bindings for Stations from Maincells

            if (c.Name != "OQC")
            {

                //Setting Qualified Overall (=Qualified from Cell Appearance Check)

                Common.BindTextBlock(QualifiedOverallTextBlock, c, "Qualified");

                if (c.Name.Contains("Appearance Check"))
                    Common.BindTextBlock(QualifiedOverallTextBlock, c, "Qualified");

                //Setting Scrap Rate (=Waste from Cell Acoustic Test)

                if (c.Name.Contains("Acoustic Test"))
                      Common.BindTextBlock(ScrapRateTextBlock, c, "WasteRate");

                AccordionItem aci = new AccordionItem();

                StackPanel sp = new StackPanel();
                StackPanel groupData = new StackPanel();
                StackPanel all = new StackPanel();
                all.Children.Add(sp);
                all.Children.Add(groupData);

                if (c.Stations != null)

                    //All Single Cell Line Controls

                    if (meas.ID != -2)
                    {
                        for (int i = 0; i < c.Stations.Count; i++)
                        {
                            NumberTextbox t = Common.CreateNumberTextbox(c.Stations[i], "Value", BindingMode.TwoWay, false, null, 80, 22);

                            t.LostFocus += new RoutedEventHandler(t_LostFocus);

                            c.Stations[i].PropertyChanged += new System.ComponentModel.PropertyChangedEventHandler(LineControl_PropertyChanged);

                            //Handling if Qualified Field is Editable

                            if (c.Stations[i].Name.Contains("Qualified"))
                            {
                                t.Background = new SolidColorBrush(Colors.BlanchedAlmond);
                                groupData.Children.Add(t);

                            }
                            else
                            {
                                sp.Children.Add(t);
                            }

                        }
                    }


                groupData.Children.Add(Common.CreateNumberTextbox(c, "RejectQty", BindingMode.OneWay, true,null, 80, 22));
                groupData.Children.Add(Common.CreateNumberTextbox(c, "PassRate", BindingMode.OneWay, true, new SolidColorBrush(Colors.BlanchedAlmond), 80, 22));
                groupData.Children.Add(Common.CreateNumberTextbox(c, "RejectRate", BindingMode.OneWay, true, new SolidColorBrush(Colors.BlanchedAlmond), 80, 22));

                aci.Header = "";
                aci.Content = all;
                MainCellsAccordion.Items.Add(aci);

            }
        }
    }

我也使用WPF工具包中的Accordion控件体验糟糕的性能。我在选项卡中有一个Accordion控件，每当我切换到该选项卡时，需要2-3秒才能初始化内容。当没有使用手风琴控制时，我没有这个问题。

我认为手风琴是你的罪魁祸首。
