Silverlight动态创建Gird

用DataGrid有时候无法定制非常个性化的界面，Grid就相当于html中的table了。
按道理可以定制任何想要的界面。如图

 void GeneralGrid()
{
    Grid grid = new Grid();
    //定义两行
    grid.RowDefinitions.Insert(0, new RowDefinition() { Height = new GridLength(20) });
    grid.RowDefinitions.Insert(1, new RowDefinition() { Height = new GridLength(20) });
    //定义两列
    grid.ColumnDefinitions.Insert(0, new ColumnDefinition() { Width = new GridLength(50) });
    grid.ColumnDefinitions.Insert(1, new ColumnDefinition() { Width = new GridLength(100) });

    TextBox txt = new TextBox();
    txt.SetValue(Grid.RowProperty, 0);//定义所在行
    txt.SetValue(Grid.ColumnProperty, 0);//定义所在列

    Button btn = new Button();
    btn.Content = "大气象";
    btn.SetValue(Grid.RowProperty, 1);
    btn.SetValue(Grid.ColumnProperty, 1);

    //添加Grid里面的动态控件
    grid.Children.Add(txt);
    grid.Children.Add(btn);

    //设置Grid的外边距
    grid.Margin = new Thickness(10, 20, 30, 40);//左上右下，顺时针

    spDataList.Children.Add(grid);//将Grid添加到StackPanel中
}

 

参考一：silverlight动态创建控件及控件事件动态指定(c#)
在写silverlight程序的某些时候难免要动态创建控件或修改控件事件，以下为示例代码：

 1 
 2 public partial class EventDemo : UserControl 
 3     { 
 4         private int newButtonPosition = 100; 
 5   
 6         public EventDemo() 
 7         { 
 8             InitializeComponent(); 
 9             //Anthor按钮单击事件 
10             Another.Click += new RoutedEventHandler(Another_Click); 
11         } 
12   
13         //Anthor按钮单击后，执行方法 
14         void Another_Click(object sender, RoutedEventArgs e) 
15         { 
16             //创建一个Button 
17             Button b = new Button(); 
18             //显示内容 
19             b.Content = "I live!"; 
20             //为新创建的控件新建Thickness对象，用来设置Button控件的位置 
21             //原文中使用了Canvas.LeftProperty和Canvas.TopProperty 
22             Thickness tn = new Thickness(10,this.newButtonPosition,0,0); 
23             b.SetValue(Canvas.StyleProperty, tn); 
24             //到顶部的距离递增 
25             this.newButtonPosition += 30; 
26             b.Width = 100; 
27             b.Height = 20; 
28             //给这个新建的按钮的Click事件添加一个处理方法 
29             b.Click += new RoutedEventHandler(b_Click); 
30             //添加到父控件，并显示 
31             myCanvas.Children.Add(b); 
32         } 
33   
34         //点击添加的控件触发 
35         void b_Click(object sender, RoutedEventArgs e) 
36         { 
37             Button btn = sender as Button; 
38             btn.Content = "Don't do that!"; 
39             btn.IsEnabled = false; 
40         } 
41     }
42

参考三：

Code below can add item that contain a button and a textbox which are lay in a grid to combobox.

ComboBoxItem item = new ComboBoxItem();
            Grid grid = new Grid();
            grid.ColumnDefinitions.Insert(0, new ColumnDefinition() { Width = new GridLength(50) });
            grid.ColumnDefinitions.Insert(1, new ColumnDefinition() { Width = new GridLength(100) });

            Button MyButton = new Button();
            MyButton.SetValue(Grid.ColumnProperty, 0);
            MyButton.DataContext = "11";
            MyButton.Click+=new RoutedEventHandler(MyButton_Click);
            TextBox textbox = new TextBox();
            textbox.Name = "text";
            textbox.SetValue(Grid.ColumnProperty, 1);

            grid.Children.Add(MyButton);
            grid.Children.Add(textbox);

            item.Content = grid;

            Combobox1.Items.Add(item);
