自定义模板 WPF DatePickerTextBox

我正在尝试使用用户
TextBox

在控制元件中
DatePicker

, 但我不能将日期与弹出日历绑定到
TextBox

. 我不想体调整体
DatePicker

没有极端的必要性，和
DatePickerTextBox

它有自己的控制，因此必须有一种方法只能改变它。 以下代码 - 这就是初学者所拥有的：


<style targettype="{x:Type DatePickerTextBox}">

 <Setter Property="Template">

 <Setter.Value>

 <ControlTemplate TargetType="{x:Type DatePickerTextBox}">

 <TextBox x:Name="PART_TextBox" Text="{Binding Path=SelectedDate}" />

 </ControlTemplate>

 </Setter.Value>

 </Setter>

</style>


也许我做了绑定错误，或者
PART_TextBox

可能是错误的，因为它不是模板本身的一部分
DatePicker

.

任何人，请帮忙！ :/

先感谢您！

    试试吧：


    <datepicker>
    
<datepicker.resources>
    
<style targettype="{x:Type DatePickerTextBox}">
    
 <Setter Property="Control.Template">
    
 <Setter.Value>
    
 <ControlTemplate>
    
 <TextBox x:Name="PART_TextBox" 
    
 Text="{Binding Path=SelectedDate, RelativeSource={RelativeSource AncestorType={x:Type DatePicker}}}" />
    
 </ControlTemplate>
    
 </Setter.Value>
    
 </Setter>
    
 </style>
    
</datepicker.resources>
    
</datepicker>

    我明白这个问题长期以来一直是答案，但是直接绑定到文本财产 DatePicker 会允许
    https://msdn.microsoft.com/en- ... .aspx
    在你的控制模板中，很容易观察短暂的/提供了长格式
    https://msdn.microsoft.com/en- ... .aspx
    .


    <datepicker>
    
<datepicker.resources>
    
<style targettype="{x:Type DatePickerTextBox}">
    
 <Setter Property="Template">
    
 <Setter.Value>
    
 <ControlTemplate>
    
 <TextBox Text="{Binding Text, RelativeSource={RelativeSource AncestorType={x:Type DatePicker}}}" />
    
 </ControlTemplate>
    
 </Setter.Value>
    
 </Setter>
    
 </style>
    
</datepicker.resources>
    
</datepicker>


    "PART_TextBox" 也没有必要，因为它不是模板的一部分 DatePickerTextBox. 单身的 PARTs, 其中包含 DatePickerTextBox, - 这是：


    [TemplatePart/Name = DatePickerTextBox.ElementContentName, Type = typeof/ContentControl//]
    
public sealed partial class DatePickerTextBox : TextBox
    

    
private const string ElementContentName = "PART_Watermark";


    并继承了ot。
    https://msdn.microsoft.com/en- ... .aspx
    ...


    [TemplatePart/Name = "PART_ContentHost", Type = typeof/FrameworkElement//] 
    
public abstract class TextBoxBase : Control
    

    
internal const string ContentHostTemplateName = "PART_ContentHost";


    替代解决方案：

    如果你拒绝使用
    https://msdn.microsoft.com/en- ... .aspx
    并使用遗传 PART, 你可以改变
    https://msdn.microsoft.com/en- ... .aspx
    如果不更改默认控制功能。


    <datepicker>
    
<datepicker.resources>
    
<style targettype="{x:Type DatePickerTextBox}">
    
 <Setter Property="Template">
    
 <Setter.Value>
    
 <ControlTemplate>
    
 <Grid SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}">
    
 <Border BorderThickness="{TemplateBinding BorderThickness}"
    
 BorderBrush="{TemplateBinding BorderBrush}"
    
 Background="{TemplateBinding Background}"/>
    

    
 <ScrollViewer Name="PART_ContentHost"
    
 HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
    
 VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
    
 </Grid>
    
 </ControlTemplate>
    
 </Setter.Value>
    
 </Setter>
    
 </style>
    
</datepicker.resources>

    如果您声明了一个元素 XAML /1/, 然后在演示中浏览它
    Design

    , 您可以右键单击 /2/ 并出口他的模板 /3/:

    <window ...attributes...="">
    
<grid>
    
<datepickertextbox></datepickertextbox>
