Windows Phone键盘逗号-点冲突 [英] Windows Phone keyboard comma - dot conflict

问题描述

我想使用数字键盘(InputScope=Number)，但想显示'，'而不是'.'.在左下角，因为它是土耳其语的小数点分隔符. 即使我在以下代码中强制使用区域性"，键盘布局也会根据电话语言而显示: System.Globalization.CultureInfo.DefaultThreadCurrentCulture = new CultureInfo("tr-TR"); System.Globalization.CultureInfo.DefaultThreadCurrentUICulture = new CultureInfo("tr-TR");

I would like to use Numeric keyboard (InputScope=Number) but want to display ',' instead of '.' on the lower-left hand corner because it is the decimal separator in Turkish language. The keyboard layout appears depending on the phone language even if I force the Culture in code like this: System.Globalization.CultureInfo.DefaultThreadCurrentCulture = new CultureInfo("tr-TR"); System.Globalization.CultureInfo.DefaultThreadCurrentUICulture = new CultureInfo("tr-TR");

如何强制数字键盘的左下角只有'，'?

How can I force numeric keyboard with only ',' on the lower-left hand corner?

或者至少我该如何检测KeyEventArgs上两个字符之间的差异?因为两者都返回Unknown as Key code(很明显是相同的键)，并且当用户按下时我无法想出一种区分它们的方法?

Or at least how can I detect the difference between the two characters on KeyEventArgs? Because both returns Unknown as Key code (well obviously same key) and I cannot come up with a way to differentiate them when user presses?

推荐答案

鉴于您无法更改键盘的区域性，您有两个选择:

Given that you can't change the culture for the Keyboard you have two options:

1. 挂钩KeyUp，如果KeyCode不知道，则您将得到.或，
2. 钩上TextChanged并检查最后一个字母是否为.或，并根据需要进行替换(请注意，如果您更新TextChanged中的文本，则将重新触发TextChanged)

例如:

    private void txt_KeyUp(object sender, System.Windows.Input.KeyEventArgs e)
    {
        if (e.Key == System.Windows.Input.Key.Unknown)
        {
            txt.Text = txt.Text.Replace('.', ',');

            // reset cursor position to the end of the text (replacing the text will place
            // the cursor at the start)
            txt.Select(txt.Text.Length, 0);
        }
    }
