C# 在C Win Phone 8应用程序中以编程方式创建一组按钮

我的C文件中有一个问题。我必须在特定位置以编程方式创建6个按钮。但是我的for循环不起作用

只显示一个按钮，而不是所有按钮

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Navigation;
using Microsoft.Phone.Controls;
using Microsoft.Phone.Shell;
//using System.Array;

namespace AimPass
{
     public partial class main : PhoneApplicationPage
     {
    public main()
     {
        InitializeComponent();

    }

private void newbutton(object sender, RoutedEventArgs e)
    {
 // How many buttons do you want ?
        int NumOfButtons = 6;
        // X Location of each created button in the panel
        int loc = 20;
        for (int i = 1; i <= NumOfButtons; i++)
        {
            Button btn = new Button();
            {
                btn.Name = "Btn-" + i.ToString();
              btn.Size= new Size(50, 20);
               btn.Tag = i;
                btn.Content = "Browse-" + i.ToString();
              btn.location = new Point(5, loc);
            }
            //Add Click event Handler for each created button
           btn.Click += Buttons_Click;
            loc += 20;
            // Add the created btn to grid
            grid.Children.Add(btn);
        }
}

}

循环不起作用。除了6个按钮外，只有一个按钮

我想在一个特定的位置添加按钮。所以这些错误符合我的要求。。

首先，Windows Phone中的按钮没有大小和位置。你为什么认为他们会这样做？除了大小之外，还有两个属性：宽度和高度

至于位置，XAML不是这样工作的。网格是一种特殊的控件，用于创建布局并定义网格中所需的列数和行数。然后将控件放置在单个单元格内，也可以使控件跨越单元格

也许您应该先了解一下XAML，这里有一个很好的起点：

- 编辑：添加用于在第一行和第一列中放置按钮的示例代码。请注意，您必须在XAML或代码中定义网格和列定义

grid.Children.Add(btn);
Grid.SetRow(btn, 0);

Grid.SetColumnbtn，0

我还没来得及弄清楚这一点……所以，看看你会得到你读到的东西。。 它有点长，但我认为它会帮助你们理解你们在寻找什么。你们可以在一个循环中同时添加行和按钮，但多一点总是好的

这是你的解决方案，但我认为你走错了路

private void newbutton()
    {
        // How many buttons do you want ?
        int NumOfButtons = 6;
        // X Location of each created button in the panel
        StackPanel stkpanel = new StackPanel();
        stkpanel.Orientation = Orientation.Horizontal;
        int loc = 20;
        for (int i = 1; i <= NumOfButtons; i++)
        {
            Button btn = new Button();
            {
                btn.Name = "Btn-" + i.ToString();
                btn.Height = 20;
                btn.Width = 50;
                btn.Foreground = new SolidColorBrush(Colors.White);
                btn.Content = "btnnum" + i.ToString();
                btn.Tag = i;
                btn.Content = "Browse-" + i.ToString();
                btn.Margin = new Thickness(5 + loc, 5, 5, 5);
                btn.VerticalAlignment = Windows.UI.Xaml.VerticalAlignment.Top;
            }
            //Add Click event Handler for each created button
            btn.Click += btn_Click;
            loc += 20;
            // Add the created btn to grid
            stkpanel.Children.Add(btn);
        }
        grid.Children.Add(stkpanel);
    }

    void btn_Click(object sender, RoutedEventArgs e)
    {
       // throw new NotImplementedException();
    }

Krybooltype n当前上下文中也不包含其他许多错误..？此类错误的可能解决方案是什么..我猜您错过了第一行。Grdbooltype是在那个里定义的。你们知道把我的控件放在网格行或列中的语法吗。。？？

private void newbutton()
    {
        // How many buttons do you want ?
        int NumOfButtons = 6;
        // X Location of each created button in the panel
        StackPanel stkpanel = new StackPanel();
        stkpanel.Orientation = Orientation.Horizontal;
        int loc = 20;
        for (int i = 1; i <= NumOfButtons; i++)
        {
            Button btn = new Button();
            {
                btn.Name = "Btn-" + i.ToString();
                btn.Height = 20;
