ContentControl.ContentStringFormat Property

Updated: July 2008

Gets or sets a composite string that specifies how to format the Content property if it is displayed as a string.

Namespace:  System.Windows.Controls
Assembly:  PresentationFramework (in PresentationFramework.dll)

public string ContentStringFormat { get; set; }
<object ContentStringFormat="string" .../>

Property Value

Type: System.String
A composite string that specifies how to format the Content property if it is displayed as a string.

ContentStringFormat can be a predefined, composite, or custom string format. For more information about string formats, see Formatting Types. If you set the ContentTemplate or ContentTemplateSelector property of a ContentControl, the ContentStringFormat property is ignored.

The following example specifies the format of DateTime objects by setting the ContentStringFormat property in a Style and applying the Style to two Label objects, which inherit from ContentControl.


    <Style x:Key="DateLabel" TargetType="Label">
      <Setter Property="ContentStringFormat" Value="dddd – d - MMMM"/>

  <!--The results when the default culture is en-US
      is March 4, 2005.-->
  <Label Style="{StaticResource DateLabel}">
    <sys:DateTime>2004/3/4 13:6:55</sys:DateTime>

  <Label Style="{StaticResource DateLabel}">
    <x:Static Member="sys:DateTime.Now"/>
