红色边框保持在文本框即使在数据输入有效 [英] Red border remains on the TextBox even after the data input is valid
问题描述
我写使用WPF,WPF应用程序框架和MahApps.Metro的应用程序。我有这样一个数据输入窗口中启用验证:
I am writing an app using WPF, WPF Application Framework and MahApps.Metro. I have validation enabled for a data entry window like this:

结果是这样的:
The result looks like this:
这看起来不错。麻烦的是,甚至当我为文本框
红色边框保持输入有效的值。就像你可以在标题和完整名称文本框见
在这里上课。我如何删除这个残留红色边框?它在哪里来的?
Which looks nice. The trouble is even when I enter valid values for a TextBox
a red border remains. Like you can see in the title and full name TextBox
es here. How do I remove this residue red border? Where is it coming from?
推荐答案
我以前也碰到过这样的,当它发生在我身上我不得不在<$ C来执行数据变化$ C>初始化和 ContentRendered
。因为我有项目实际上约束。
I've come across this before, when it happened to me I had to perform a data change during initialize
and ContentRendered
. Cause I had the items actually bound.
我看到前一段时间对堆栈溢出的另一件事是,在这里发生一个问题,也造成了类似的事情。
Another thing I saw awhile ago on Stack Overflow was an issue that happened here that also caused something similar.
<Setter Property="Validation.ErrorTemplate">
<Setter.Value>
<ControlTemplate>
<ControlTemplate.Resources>
<BooleanToVisibilityConverter x:Key="converter" />
</ControlTemplate.Resources>
<DockPanel LastChildFill="True">
<Border
BorderThickness="1"
BorderBrush="Red"
Visibility="{Binding ElementName=placeholder, Mode=OneWay, Path=AdornedElement.IsVisible, Converter={StaticResource converter}}">
<AdornedElementPlaceholder x:Name="placeholder" />
</Border>
</DockPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
这是我的遭遇,如果不帮忙,我会尝试重现该问题并修复为好。看我能不能帮你出好一点的话,描述我是如何固定它。但希望这两项建议都能帮助你。
That was my encounter, if that doesn't help I'll attempt to recreate the issue and fix as well. See if I can help you out a little better then describing how I fixed it. But hopefully one of those two suggestions helps you out.
只要让我知道,希望它帮助。
Just let me know, hope it helps.
