  1. <Page.Resources>  
  2.   
  3.         <Style x:Key="vikasTextboxStyle" TargetType="TextBox">  
  4.             <Setter Property="Template">  
  5.                 <Setter.Value>  
  6.                     <ControlTemplate TargetType="TextBox">  
  7.   
  8.                         <ContentControl x:Name="PlaceholderTextContentPresenter"  
  9.                               Grid.Row="1"    
  10.                               Margin="{TemplateBinding BorderThickness}"  
  11.                               Padding="{TemplateBinding Padding}"  
  12.                               IsTabStop="False"  
  13.                               Grid.ColumnSpan="2"  
  14.                               Content="{TemplateBinding PlaceholderText}"   
  15.                               IsHitTestVisible="False"/>  
  16.                     </ControlTemplate>  
  17.                 </Setter.Value>  
  18.             </Setter>  
  19.         </Style>  
  20.     </Page.Resources>  

And add the key in Style but remember that the key name should be same as you given in page.resourse style tag and write the code in textbox as given in the below screenshot.

  1. <Style="{StaticResource vikasTextboxStyle}">  
  2.   
  3. <TextBox.Resources>    
  4.                         <Style TargetType="ContentControl">    
  5.                             <Setter Property="Foreground" Value="Green"/>    
  6.                         </Style>    
  7.  </TextBox.Resources>    

For a complete sample, you can use the code below.
