運行時更改大小按鈕（wpf）

爲什麼IsMouseOver中的大小不會更改？運行時更改大小按鈕（wpf）

實例應用：

<Button Style="{DynamicResource GlassButton}" Content="Button" Height="23" HorizontalAlignment="Left" Margin="534,262,0,0" Name="button1" VerticalAlignment="Top" Width="75" />

您可以嘗試將屬性更改爲ActualHeight和RenderWidth，看看會發生什麼？你也確定模板綁定到你的按鈕？你可以在你創建按鈕的地方放置代碼嗎？ –

我要更改尺寸按鈕 – mrJack

這是一個示例用法嗎？或者，您的代碼中是如何創建該按鈕的？別的東西可能會影響你沒有向我們展示的尺寸。您是否嘗試將屬性更改爲ActualHeight和RenderWidth？發生了什麼？ –

你有一個屬性設置優先發布。請參閱WPFTutorial.net上的優先表（請參閱值解析策略部分）。

您Button取出Height和Width設置，如果你需要的初始大小這些setter方法添加到您的風格：

<Setter Property="Height" Value="23"/> 
<Setter Property="Width" Value="75"/>

而且，要小心混合添加尺寸爲你....
