这篇文章主要为大家详细介绍了如何基于WPF实现自定义弹窗输入功能,文中的示例代码讲解详细,具有一定的借鉴价值,感兴趣的小伙伴可以了解下
功能介绍：
本文主要介绍了如何使用WPF实现自定义弹窗输入效果，整体采用了Grid和DockPanel混合布局，顶部为输入控制区,有文本框、四个功能按钮(OK/Del/Clear/Cancel)和一个大小写复选框；底部右侧为3x4数字键盘布局,包含数字0-9按钮。下面我们就来看看具体实现代码吧
完整代码如下：

}
private void Load(bool isCase = false)
{
try

for (int i = 0; i < letterList.Count; i++)
{
string name = string.Format("Button_Letter_{0}", i + 1);
Button but = this.UniformGrid_Letter.FindName(name) as Button;
if (isCase)
{
but.Content = letterList[i].ToUpper();
}
else
{
but.Content = letterList[i].ToLower();
}
}
}
catch
{
}
}
#region 值输入

3.自定义Button样式
<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>
