BorderColor property

Background and motivation

Now, I can customize only presence of border, but not color. For customizing, it would be cool to have property BorderColor. For example, in Button or Panel.

API Proposal

public
Color
BorderColor
{ get; set; }

API Usage

Panel.BorderColor = Color.Black;

Risks

I don’t see risks. The color is set inside realization, or is taken from system settings. The only difference - it will be rised up to user for customization.

Will this feature affect UI controls?

VS Designer need to support the feature.

ButtonBase-derived controls can customise their border if those are rendered in “flat” style -> https://learn.microsoft.com/dotnet/api/system.windows.forms.flatbuttonappearance.bordercolor?view=windowsdesktop-7.0#system-windows-forms-flatbuttonappearance-bordercolor.

Now I see. Thanks.

Documentation should mark that you have to set Button.FlatStyle = Flat in order to use property FlatAppearance. It is not obvious.

That border is rendered by Windows, and it’s not really customisable. If you want a custom border you have to draw it yourself.

Sounds like you don’t want additional work 😃 .
