Sorry, I tested this situation with C1Input version 4.0.20171.248 and the problem has not been fixed at all. As you can see my attached screenshot, three controls at top (C1DropDown, C1DateEdit, C1NumericEdit) have small arrow images, the last one is standard ComboBox with properly size arrow image in DPI scaling 200%.
I tested on Windows 10 64bit in 200% DPI scaling, the sample has built with dpiAware=True setting in manifest file.
Some other small issue:
- All C1DropDown, C1DateEdit, C1NumericEdit got some flicker at drop-down button when user moves mouse on them.
- When I change properties of C1DropDown, C1DateEdit, C1NumericEdit: VisualStyle=System and BorderStyle=Fixed3D and my Windows OS theme is disabled, they still have flat border instead of classic 3D border as standard TextBox, ComboBox... (you can see in my attach screenshot).
- By the way, could you add an option for C1Input controls to able to custom draw drop-down button totally by coding. Now, I can assign custom image to ButtonImages but C1Input controls always add some effect (drawing border, changing background color of my custom image) when mouse hovered.
Thank you!
