基于WPF實現(xiàn)自定義彈窗輸入功能
更新時間：2025年07月02日 09:25:05 作者：加號3
這篇文章主要為大家詳細介紹了如何基于WPF實現(xiàn)自定義彈窗輸入功能,文中的示例代碼講解詳細,具有一定的借鑒價值,感興趣的小伙伴可以了解下
功能介紹：
本文主要介紹了如何使用WPF實現(xiàn)自定義彈窗輸入效果，整體采用了Grid和DockPanel混合布局，頂部為輸入控制區(qū),有文本框、四個功能按鈕(OK/Del/Clear/Cancel)和一個大小寫復選框；底部右側為3x4數(shù)字鍵盤布局,包含數(shù)字0-9按鈕。下面我們就來看看具體實現(xiàn)代碼吧
完整代碼如下：

<Style x:Key="ButtonSizeAdaptive" TargetType="Button">
<Setter Property="VerticalContentAlignment" Value="Center" />
<Setter Property="VerticalAlignment" Value="Stretch" />
<Setter Property="HorizontalAlignment" Value="Stretch" />
<Setter Property="HorizontalContentAlignment" Value="Center" />
<Setter Property="Height" Value="Auto" />
<Setter Property="Width" Value="Auto" />
<Setter Property="FontSize" Value="30" />
<Setter Property="FontWeight" Value="Bold" />
</Style>
