DPI scaling not performed in RadPageView

Hi, Sven,

In order to produce as good layout as possible when running your application on monitors with different DPI scaling, it is important to have some thoughts in mind before you start designing the application: https://docs.telerik.com/devtools/winforms/knowledge-base/hdpi-tips-and-tricks 

I would like to note that in the upcoming R2 2022 (scheduled for this week) we have added some improvements to how our controls are scaled in their parent Forms/RadForms. The following improvements are listed below. These new functionalities are controlled by the static RadControl.EnableRadAutoScale property. In a case, you want to disable these improvements you can set it false.
- RadControl is dynamically scaled now when it is added runtime.
- RadControl is scaled correctly in a System.Windows.Forms.Form.
- RadControl is scaled correctly in an UserControl.
- Scaling works in all .NET versions and DPI Awareness modes combinations except in .Net4 Framework. In this version, the scaling will not work in Microsoft Form.
- Fixed various DPI-related scaling issues.
Stay tuned and once the version is released, you can give your project another try. As I noted in the support ticket you have opened on the same topic, an alternative approach is to test your project in advance on our end. You can provide your project in the support ticket and we will have a look at it.

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
