如何将文本框的边框颜色重置为默认系统颜色

Question

I'm changing the color of a textbox to red for validation in WPF

I can't find a way to change it back to the system default upon clearing my form.

I thought there was an easy way to change it back to the default by clearing the border brush proper but I can't seem to find it.

Is there an easy way to reset it to the default with out having to set it manually to the system color?

Answer 1

了解如何做：

Textbox.ClearValue(Border.BorderBrushProperty)

Answer 2

TextBox.BorderColor = Color.Empty
