我想將圖像作爲按鈕背景,我看到很多關於此問題的問題,而更好的方法似乎是創建自定義ImageButton的子類化按鈕。將自定義ImageButton控件添加到Windows Phone項目
無論如何,我試圖用圖像刷到圖像設置按鈕的背景,但它不工作,這樣的事情:
Button b = new Button();
ImageBrush ib = new ImageBrush();
ib.ImageSource = home;
b.Background = ib;
並設置圖片作爲內容:
Image i = new Image();
i.Source = home;
Button b = new Button();
b.Content = home;
然後我看到一個ImageButton class,我下載並添加到項目中。
,但我不能編譯
static ImageButton() {
DefaultStyleKeyProperty.OverrideMetadata(typeof(ImageButton), new FrameworkPropertyMetadata(typeof(ImageButton)));
}
public static readonly DependencyProperty ImageSizeProperty =
DependencyProperty.Register("ImageSize", typeof(double), typeof(ImageButton),
new FrameworkPropertyMetadata(30.0, FrameworkPropertyMetadataOptions.AffectsRender));
基本上我得到這個錯誤:
'System.Windows.DependencyProperty' does not contain a definition for 'OverrideMetadata' and no extension method 'OverrideMetadata' accepting a first argument of type 'System.Windows.DependencyProperty' could be found (are you missing a using directive or an assembly reference?)
The type or namespace name 'FrameworkPropertyMetadata' could not be found (are you missing a using directive or an assembly reference?)
The name 'FrameworkPropertyMetadataOptions' does not exist in the current context
有人能告訴我怎麼解決這個問題?或者如果我做錯了放置背景圖片或製作圖片的方式,只需要一個帶有填充圖片的按鈕,而無需填充或邊距或邊框。
