如何将Style控件的样式应用于Silverlight中的内容模板中的Child控件 [英] How to apply Style of Parent control to Child controls in content template in Silverlight

问题描述

此处我的TextBox文本正在与contentemplate中的子文本框绑定，但如何将默认样式和验证错误应用于内容模板中的子文本框。

< TextBox x：Name =" tbIdNumber"宽度= QUOT; 110"高度= QUOT; 20" 
 Text =" {Binding IdNumber，Mode = TwoWay，ValidatesOnExceptions = true，NotifyOnValidationError = true}"> 
< TextBox.Template> 
< ControlTemplate TargetType =" TextBox" > 
< StackPanel Orientation =" Horizo​​ntal" > 
< Image Height =" 10"宽度= QUOT; 20"源= QUOT;图像/ bullet_darkblue.PNG" /> 
< TextBox Width =" 90" 
 Tag =" {Binding RelativeSource = {RelativeSource TemplatedParent}}" 
 DataContext =" {Binding RelativeSource = {RelativeSource TemplatedParent}，Path = DataContext，Mode = TwoWay}" 
 Text =" {Binding Path = Text，RelativeSource = {RelativeSource TemplatedParent}，Mode = TwoWay，ValidatesOnExceptions = true，
 NotifyOnValidationError = true}" > 
< / TextBox> 
< / StackPanel> 
< / ControlTemplate> 
< /TextBox.Template> 
< / TextBox> 

解决方案

使用如下的TemplateBinding

 <   TextBox    x  ： 名称  =  " tbIdNumber"    宽度  =  " 110"   高度  =  " 20"    文字  =" {  Binding    IdNumber  < span style ="color：blue">，  模式  =   TWOW ay  ，   ValidatesOnExceptions   =   true  ，   NotifyOnValidationError  < span style ="color：blue"> =   true  }  " 的&NBSP;>

        <TextBox.Template>             	
            <ControlTemplate TargetType="TextBox" >                                     	
                <StackPanel Orientation="Horizontal" >                    	
                    <Image Height="10" Width="20" 	Source="Images/bullet_darkblue.PNG" />                     
                    <TextBox   Width="90"   	
                        Tag="{Binding RelativeSource={RelativeSource TemplatedParent}}"    
                        DataContext="{Binding RelativeSource={RelativeSource TemplatedParent},Path=DataContext, Mode=TwoWay}"
                        Text="{Binding  Path=Text ,RelativeSource={RelativeSource TemplatedParent}, Mode=TwoWay, ValidatesOnExceptions=true, 
                            NotifyOnValidationError=true}"  >                                               
                    </TextBox>                 
                </StackPanel>              
            </ControlTemplate>         
        </TextBox.Template>     
    </TextBox>  

解决方案

Use TemplateBinding as below

<TextBox x:Name="tbIdNumber"  Width="110" Height="20"  Text="{Binding IdNumber, Mode=TwoWay, ValidatesOnExceptions=true, NotifyOnValidationError=true}" >
            <TextBox.Template>
                <ControlTemplate TargetType="TextBox" >
                    <StackPanel Orientation="Horizontal" >
                        <Image Height="10" Width="20" Source="Images/bullet_darkblue.PNG" />
                        <TextBox Width="90" Tag="{TemplateBinding Tag}" DataContext="{TemplateBinding DataContext}" Text="{TemplateBinding Text}"/>
                    </StackPanel>
                </ControlTemplate>
            </TextBox.Template>
        </TextBox>
