如何在WPF C＃中隐藏datepicker图标？
我要隐藏默认的DatePicker图标：
我需要类似的东西：
<DatePicker IconVisibality="False"/>
我尝试过：
Template="{x:Null}"
但是它全部隐藏了。
我也尝试过：
Foreground="{x:Null}"
有人知道吗？

您需要创建一个自定义模板。您可以在Visual Studio或Blend中的设计模式下右键单击DatePicker元素，然后选择“编辑模板”->“编辑副本”以将默认模板复制到XAML标记中，然后删除Button名为“ PART_Button”的元素：
<DatePicker>
<DatePicker.Style>
<Style TargetType="{x:Type DatePicker}">

只需用另一种样式（如此样式）覆盖您的模板，然后使用StaticResource将其引用到DatePicker。
<Style x:Key="WithoutButtonPickerStyle" TargetType="{x:Type DatePicker}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type DatePicker}">
<Grid x:Name="PART_Root" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<DatePickerTextBox x:Name="PART_TextBox">...</DatePickerTextBox>
<Button x:Name="PART_Button" Visibility="Hidden"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

一种更简便的方法是创建自定义控件。
public class CustomDatePicker:DatePicker
{
public override void OnApplyTemplate()
{
base.OnApplyTemplate();
if (Template.FindName("PART_Button", this) is Button button)
{
button.Visibility = System.Windows.Visibility.Hidden;
}
}
}
然后在Xaml中使用
<local:CustomDatePicker />
