動態添加按鈕（工具提示和文本）

如果按鈕是從後面的代碼動態添加到wpf中，您如何將工具提示添加到它們或文本到實際按鈕？動態添加按鈕（工具提示和文本）

這是你會在窗口的形式做什麼，但我不認爲你可以在WPF中做到這一點：

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); 
     } 
    } 
}

}

至於加不文本我確定？

這裏是XAML：

您是否嘗試過使用Tooltip-屬性？

可以分配一個ToolTip到Button的ToolTip屬性和Content屬性設置爲文本要顯示：

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

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

如果您想讓按鈕顯示出來，你必須將它添加到它應該屬於的面板上 - 我認爲它是canavs：

// 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);

如果我有按鈕開始，會有所幫助。只是沒有顯示任何使用這種方法。 – 2012-03-23 20:29:34

'foo.Content =「將鼠標懸停在我身上」;'這種方法可行，但將它們設置爲全部，而不是單獨設置，就像我說的那樣設置了個性化 – 2012-03-23 20:35:10

@KirstyWhite：我添加了一些示例代碼以顯示如何將按鈕添加到畫布上它會顯示出來。不確定你是什麼意思的「設置他們全部」。你創建你需要的所有按鈕（也許在一個循環中），併爲每個按鈕設置內容屬性，以便將文本轉換爲你喜歡的文本。 – ChrisWue 2012-03-23 21:30:59
