WPF DatePicker日期不会与区域性切换 [英] WPF DatePicker date doesn't switch with culture

问题描述

我实际上找到了此，但是就像OP所说的那样，这是一种骇人听闻的解决方案，就像选票上所说的那样，不是一个漂亮的解决方案.我的程序只有一个窗口.

我有一个界面，其中包含2种可能的区域性，即de-DE和en-US，以及一个用于切换语言的按钮.

当我按下该按钮时，每个文本都会更改，只有DatePickers texbox中的文本不会更改，直到我单击DatePickers按钮，然后它将显示的日期更改为正确的格式(并打开DatePicker弹出窗口). /p>

如何使显示的日期与语言切换?我可以使用一些wpf选项来更新显示的日期吗?

它只有Binding是SelectedDate="{Binding Path=FileDate, Mode=TwoWay}，并且到目前为止效果很好.

我尝试在语言切换上执行以下操作，但不会使文本更改:

Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo((string)getSetting("Language"));
Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo((string)getSetting("Language"));
FileDate = FileDate; //This one Notifies about the propertychange, so I hoped it would refresh the text.

解决方案

好，所以我有了另一个想法，它很好用，不像是hack，很容易做到:

切换语言时，除了设置CurrentCulture和CurrentUICulture之外，我还进行

FileDate = DateTime.Now;

这使DatePicker意识到文化已经改变.

I actually found this, but like the OP says it's a hacky solution, and like the votes say not a beautiful one. My program has one window.

I have a UI with 2 possible cultures, de-DE and en-US, and a button that switches the language.

Every text changes when I press that button, only the text in the DatePickers texbox doesn't, until I click on the DatePickers button, then it changes the shown date to the right format (and opens the DatePicker popup).

How can I make the shown date switch with the language? Isn't there some wpf option I can use to make it update the shown date?

Only Binding it has is SelectedDate="{Binding Path=FileDate, Mode=TwoWay}, and it works well so far.

I tried doing the following on switch of language, but it doesn't make the text change:

Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo((string)getSetting("Language"));
Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo((string)getSetting("Language"));
FileDate = FileDate; //This one Notifies about the propertychange, so I hoped it would refresh the text.

解决方案

Ok so I got another idea, and it works great, doesn't feel like a hack, and is easy to do:

When switching the language, beside setting the CurrentCulture and CurrentUICulture, I go

FileDate = DateTime.Now;

That apperently makes the DatePicker realize the Culture has changed.
