[UWP]当屏幕分辨率为1920 * 1080时，边框厚度未正确应用 [英] [UWP]Border Thickness is not applied properly when screen resolution is 1920*1080

问题描述

如果我将TextBox的边框粗细设置为0.4以下，则当屏幕分辨率为1920 * 1080时，边框不可见。

如果分辨率为1366 * 768，则可正常工作。

< TextBox Name =" textBox1"了borderThickness = QUOT; 0.2" /> 

请您仔细研究并提供解决方案吗？ 

解决方案

Hello Priya VR，

您是否尝试为TextBox设置BorderBrush以查看是否可以在那个分辨率中看到它？

< TextBox Name =" textBox1"了borderThickness = QUOT; 0.2" BorderBrush = QUOT;红色" /> 

我认为这很正常。它实际上是可见的，只是由于高分辨率，你的眼睛无法区分它。

我建议你可以根据当前的屏幕分辨率改变BorderThickness。请参考以下代码以供参考：

 var bounds = ApplicationView.GetForCurrentView（）。VisibleBounds; 
 var scaleFactor = DisplayInformation.GetForCurrentView（）。RawPixelsPerViewPixel; 
 var size = new Size（bounds.Width * scaleFactor，bounds.Height * scaleFactor）;

If I set TextBox's border thickness below 0.4, border is not visible when screen resolution is 1920*1080.
It works correctly if the resolution is 1366 * 768.

 <TextBox Name="textBox1" BorderThickness="0.2" />

Could you please look into this and provide the solution to overcome? 

解决方案

Hello Priya VR,

Have you tried to set BorderBrush for TextBox to see if you can see it in that resolution?

<TextBox Name="textBox1" BorderThickness="0.2" BorderBrush="Red" />

I think it’s normal. It’s actually visible, just due to the high resolution, your eyes cannot distinguish it.

I would suggest you could change BorderThickness according to current screen resolution. Please refer to the following code for reference:

var bounds = ApplicationView.GetForCurrentView().VisibleBounds;
var scaleFactor = DisplayInformation.GetForCurrentView().RawPixelsPerViewPixel;
var size = new Size(bounds.Width * scaleFactor, bounds.Height * scaleFactor);
