Wpf文本框错误红色边框不正确显示文本框的宽度 [英] Wpf textbox error red border is not proper showing to the width of textbox

问题描述

我正面临一个问题，即一旦我的wpf页面被加载，然后需要的文本框显示红色边框不正确显示在文本框上。红色边框仅显示90％的文本框宽度未满。输入值后&从文本框中删除值，正确显示红色边框消息意味着显示红色边框100％宽度的文本框。



当我修复文本框的宽度时，红色边框是正确显示，但我想要文本框的响应宽度。





以下代码为：

Hi, I'm facing one problem that is once my wpf page is loaded then required textbox showing red border not proper displaying over textbox. The Red border displaying only 90% width of textbox not full. After enter the value & remove the value from textbox, Red border message is showing in properly means displaying Red border 100% width of textbox.

When I Fixed the width of textbox then red border is displaying properly but I want responsive width of textbox.


Following code is:

<Style TargetType="TextBox">
            <Style.Triggers>
                <Trigger Property="Validation.HasError" Value="True">
                    <Setter Property="ToolTip"
                        Value="{Binding RelativeSource={x:Static RelativeSource.Self},
                        Path=(Validation.Errors)[0].ErrorContent}"/>
                </Trigger>
            </Style.Triggers>
        </Style>
