Format Date/Time in XAML in Silverlight

问题:

I have a Silverlight 4 application. I have a C# DateTime object that I'm binding to my UI. I want this DateTime to be in the format of dd/mm/yyyy time (TimeZone). For instance, today would be displayed as

04/07/2011 at 01:13 p.m. (EST)

Is there a way to do this XAML? Or do I need to build a converter?

回答1:

<TextBlock Text="{Binding Date, StringFormat='{}{0:MM/dd/yyyy a\\t h:mm tt}'}" />

will return you

04/07/2011 at 1:28 PM (-04)

回答2:

You can use StringFormat in Silverlight 4 to provide a custom formatting of the value you bind to.

Dates

The date formatting has a huge range of options.

For the DateTime of “April 17, 2004, 1:52:45 PM”

You can either use a set of standard formats (standard formats)…

StringFormat=f : “Saturday, April 17, 2004 1:52 PM”
StringFormat=g : “4/17/2004 1:52 PM”
StringFormat=m : “April 17”
StringFormat=y : “April, 2004”
StringFormat=t : “1:52 PM”
StringFormat=u : “2004-04-17 13:52:45Z”
StringFormat=o : “2004-04-17T13:52:45.0000000”

… or you can create your own date formatting using letters (custom formats)

StringFormat=’MM/dd/yy’ : “04/17/04”
StringFormat=’MMMM dd, yyyy g’ : “April 17, 2004 A.D.”
StringFormat=’hh:mm:ss.fff tt’ : “01:52:45.000 PM”

you can also use just

StringFormat=d

in your datagrid column for date time showing

finally it will be

   <sdk:DataGridTextColumn  Binding="{Binding Path=DeliveryDate,StringFormat=d}" Header="Delivery date" Width="*" />

the out put will look like

In SL5 I found this to work:

<TextBlock Name="textBlock" Text="{Binding JustificationDate, StringFormat=dd-MMMM-yy hh:mm}">
<TextBlock Name="textBlock" Text="{Binding JustificationDate, StringFormat='Justification Date: \{0:dd-MMMM-yy hh:mm\}'}">

C#: try this

• yyyy(yy/yyy) - years
• MM - months(like '03'), MMMM - months(like 'March')
• dd - days(like 09), ddd/dddd - days(Sun/Sunday)
• hh - hour 12(AM/PM), HH - hour 24
• mm - minute
• ss - second

Use some delimeter,like this:

1. MessageBox.Show(DateValue.ToString("yyyy-MM-dd")); example result: "2014-09-30"
2. empty format string: MessageBox.Show(DateValue.ToString()); example result: "30.09.2014 0:00:00"
