動的に追加されたボタン（ヒントとテキスト）

Question

wpfのコードが動的に追加されている場合、それらにツールチップを追加したり、実際のボタンにテキストを追加したりできますか？

これは、Windowsフォームで何をするのかですが、私はあなたがWPFでそれを行うことができると思ういけない：わからないテキストIMを追加するよう

partial class Window1 
{ 
    void button3Click(object sender, RoutedEventArgs e) 
    { 
     //toolTip1.SetToolTip(this.button1, "My button1"); 
     MessageBox.Show("action 3"); 
    } 
    void button2Click(object sender, RoutedEventArgs e) 
    { 
     MessageBox.Show("action 2"); 
    } 
    void button1Click(object sender, RoutedEventArgs e) 
    { 
     MessageBox.Show("action 1"); 
    } 

    public Window1() 
    { 
     this.InitializeComponent(); 
     populateButtons(); 
     //ToolTip toolTip1 = new ToolTip(); 

     //// Set up the delays for the ToolTip. 
     //toolTip1.AutoPopDelay = 5000; 
     //toolTip1.InitialDelay = 1000; 
     //toolTip1.ReshowDelay = 500; 
     //// Force the ToolTip text to be displayed whether or not the form is active. 
     //toolTip1.ShowAlways = true; 

    } 

    public void populateButtons() 
    { 
     int xPos; 
     int yPos; 


     Random ranNum = new Random(); 
     foreach (var routedEventHandler in new RoutedEventHandler[] { button1Click, button2Click, button3Click }) 
     { 

      Button foo = new Button(); 
      Style buttonStyle = Window.Resources["CurvedButton"] as Style; 
      int sizeValue = 100; 

      foo.Width = sizeValue; 
      foo.Height = sizeValue; 

      xPos = ranNum.Next(200); 
      yPos = ranNum.Next(250); 

      //canvas1.HorizontalAlignment = HorizontalAlignment.Left; 
      //canvas1.VerticalAlignment = VerticalAlignment.Top; 
      //canvas1.Margin = new Thickness(xPos, yPos, 0, 0); 

      foo.HorizontalAlignment = HorizontalAlignment.Left; 
      foo.VerticalAlignment = VerticalAlignment.Top; 
      foo.Margin = new Thickness(xPos, yPos, 0, 0); 
      foo.Style = buttonStyle; 

      foo.Click += routedEventHandler; 

      LayoutRoot.Children.Add(foo); 
     } 
    } 
} 

}

Answer 1

Tooltip - プロパティを使用しようとしましたか？

Answer 2

あなたはButtonのToolTipプロパティにToolTipを割り当てると、表示したいテキストにContentプロパティを設定することができます。

ToolTip t = new ToolTip(); 
t.Content = "Something helpful"; 

Button b = new Button; 
b.Content = "Hover over me"; 
b.ToolTip = t; 

あなたの場合明らかにボタンを表示させたいのですが、それをパネルに追加する必要があります。それはキャンバスだと思います：

// add the button to the canvas 
canvas1.Children.Add(b); 
// set the position of the button on the canvas 
Canvas.SetLeft(b, 20); 
Canvas.SetTop(b, 20);
