C# Silverlight-如何将文本框添加到代码隐藏中的堆栈面板

这只是一个让它工作的测试应用程序

我的主页绑定到我的viewmodel，其中包含创建文本框的代码

private void Generate(object obj)
    {
        StackSG = new StackPanel();
        StackSGName = new StackPanel();

        int st = 10;
        for (int i = 0; i < st; i++)
        {
            TextBox txtSG = new TextBox();
            txtSG.Name = string.Format("{0}{1}", "Te", i.ToString());
            txtSG.Height = 25;
            txtSG.Text = string.Format("{0}{1}", "Te", i.ToString());
            txtSG.IsReadOnly = true;
            StackSG.Children.Add(txtSG);

            //Add SG name textboxes                        
            TextBox txtSGName = new TextBox();
            txtSGName.Name = string.Format("{0}{1}", "Test", i.ToString());
            txtSGName.Height = 25;
            txtSGName.Text = string.Format("{0}{1}", "Test", i.ToString());
            txtSGName.IsReadOnly = true;
            StackSGName.Children.Add(txtSGName);
        }
    }

这是我的xaml

<StackPanel x:Name="StackSG" Grid.Row="1" Grid.Column="0"/>
<StackPanel x:Name="StackSGName" Grid.Row="1" Grid.Column="1"/>

在这里，我尝试添加文本框

private void Generate(object obj)
    {
        StackSG = new StackPanel();
        StackSGName = new StackPanel();

        int st = 10;
        for (int i = 0; i < st; i++)
        {
            TextBox txtSG = new TextBox();
            txtSG.Name = string.Format("{0}{1}", "Te", i.ToString());
            txtSG.Height = 25;
            txtSG.Text = string.Format("{0}{1}", "Te", i.ToString());
            txtSG.IsReadOnly = true;
            StackSG.Children.Add(txtSG);

            //Add SG name textboxes                        
            TextBox txtSGName = new TextBox();
            txtSGName.Name = string.Format("{0}{1}", "Test", i.ToString());
            txtSGName.Height = 25;
            txtSGName.Text = string.Format("{0}{1}", "Test", i.ToString());
            txtSGName.IsReadOnly = true;
            StackSGName.Children.Add(txtSGName);
        }
    }

private void生成（object obj）
{
StackSG=新的StackPanel（）；
StackSGName=new StackPanel（）；
int st=10；
对于（int i=0；i

它运行时没有错误，但不会在我的文本框中添加广告。

也许这可以帮助您：

xaml

视图模型：

public class ViewModel : INotifyPropertyChanged
{
    public ViewModel()
    {
        StackSG = new List<TextBox>();
        StackSGName = new List<TextBox>();
        Generate(null);
    }

    private IEnumerable stackSG;
    public IEnumerable StackSG
    {
        get { return stackSG; }
        set
        {
            stackSG = value;
            OnNotifyPropertyChanged("StackSG");
        }
    }

    private IEnumerable stackSGName;
    public IEnumerable StackSGName
    {
        get { return stackSGName; }
        set
        {
            stackSGName = value;
            OnNotifyPropertyChanged("StackSGName");
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;
    public void OnNotifyPropertyChanged(string propName)
    {
        if (PropertyChanged != null)
        {
            PropertyChanged(this, new PropertyChangedEventArgs(propName));
        }
    }

    private void Generate(object obj)
    {
        IList<TextBox> StackSGTmp = new List<TextBox>();
        IList<TextBox> StackSGNameTmp = new List<TextBox>();

        int st = 10;
        for (int i = 0; i < st; i++)
        {
            TextBox txtSG = new TextBox();
            txtSG.Name = string.Format("{0}{1}", "Te", i.ToString());
            txtSG.Height = 25;
            txtSG.Text = string.Format("{0}{1}", "Te", i.ToString());
            txtSG.IsReadOnly = true;
            StackSGTmp.Add(txtSG);

            //Add SG name textboxes                        
            TextBox txtSGName = new TextBox();
            txtSGName.Name = string.Format("{0}{1}", "Test", i.ToString());
            txtSGName.Height = 25;
            txtSGName.Text = string.Format("{0}{1}", "Test", i.ToString());
            txtSGName.IsReadOnly = true;
            StackSGNameTmp.Add(txtSGName);
        }

        StackSG = StackSGTmp;
        StackSGName = StackSGNameTmp;
    }
}

您是否检查了父网格的行和列的宽度和高度？另外，您是否为stackpanel设置了一个静态高度，以确保文本框可以显示？按照我需要的方式100%工作。谢谢你的帮助！
