在Windows Phone应用程序中的MVVM中格式化数据

Question

I have a DataModel and a ViewModel working successfully together with my xaml view. In the view I use databindings.

In my DataModel I have some properties like Distance declared as int .

When displaying the values in view, I want a formatting like adding a trailing meter .

How get this done?

Answer 1

您可以在xaml绑定中格式化字符串...

<TextBlock Text="{Binding Distance, StringFormat={} {0} meter}"/>

Answer 2

Maybe by providing a property which will return a formatted value:

private int distance = 0;
public int Distance
{
   get { return distance;}
   set { distance = value; OnPropertyChanged("DistanceTxt"); }
}

public string DistanceTxt
{
   get { return distance.ToString() + " meter"; }
}

Then when you bind to DistanceTxt you should get your distance with trailing meter . I've also added OnPropertyChanged in Distance property so that when it changes, your value on the screen updates.
