调整系统的dpi时控制调整大小 [英] Control resize when dpi of system is chenged

问题描述

大家好，

由于这个原因，每当我将系统的dpi更改为DevEx组控件的125％时，控件内部的列表框也会被调整大小，并且不可见.

任何人都可以帮忙..提前谢谢

解决方案

要避免在较大的DPI上扩展WPF内容，您唯一可以做的就是检查应用程序系统DPI，并在找到非标准DPI时调整其内容的大小.这是检查DPI的方法

矩阵m =
PresentationSource.FromVisual(Application.Current.MainWindow).CompositionTarget.TransformToDevice;
double dx = m.M11;
double dy = m.M22;

The only thing you can do to avoid stretching WPF content on larger DPI, is to make your application check the system DPI and resize it's content when it finds non-standard DPI. Here's how to check the DPI

Matrix m =
PresentationSource.FromVisual(Application.Current.MainWindow).CompositionTarget.TransformToDevice;
double dx = m.M11;
double dy = m.M22;
