TextBlock与格式化字符串绑定 [英] TextBlock binding with formatted string

问题描述

我正在使用TexBlock来显示一些有界数据'Value1'。

如何在Value1之后添加一些静态文本？???? / p>

所以如果Value1 =" 1234567"

我想在之后添加一些静态文本'（以毫秒为单位）'

所以最终结果是   1234567（以毫秒为单位的时间）

我最初的猜测是使用StringFormat，但我是菜鸟，以前从未使用它。有没有一个好的资源显示我如何展示？另外，如果我遇到问题，StringFormat实际上会是什么。非常感谢！

 

< TextBlock Grid.Column =" 3" Grid.Row = QUOT; 0" Style =" {DynamicResource TextValueStyle}" Text =" {Binding Path = Value1}" /> 

解决方案

您可以使用IValueConverter。

 
  public   class  TextValueConverter：IValueConverter 
 {
  #region  IValueConverter成员
 
  public   object 转换（ object 值，Type targetType， object 参数，System.Globalization.CultureInfo文化）
 {
  return  String.Format （" {0}（{1}）" ，value，DateTime.Now.TimeOfDay.TotalMilliseconds（））; 
} 
 
  public   object  ConvertBack（ object 值，类型targetType， object 参数，System.Globalization.CultureInfo文化）
 {
  throw   new  NotImplementedException（）; 
} 
 
 ＃endregion  
} 
 

I'm using a TexBlock to display some bounded data 'Value1'.

How do I add some static text to be displayed after the Value1????

so if Value1 = "1234567"

I want to add some static text afterwards '(time in milliseconds)'

So the end result is   1234567 (time in milliseconds)

My initial guess is to use a StringFormat, but I am rookie and am never used it before. Is there a resource which is good which shows how I can display? Also what would the StringFormat actually be in case I run into problems. Thank you very much!

 

 <TextBlock Grid.Column="3" Grid.Row="0" Style="{DynamicResource TextValueStyle}" Text="{Binding Path=Value1}" />

解决方案

You could use an IValueConverter.

  public class TextValueConverter : IValueConverter
  {
    #region IValueConverter Members

    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
      return String.Format("{0} ({1})", value, DateTime.Now.TimeOfDay.TotalMilliseconds());
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
      throw new NotImplementedException();
    }

    #endregion
  }
