Caret disappears when the background of a textbox is gray in wpf

问题

I have a textbox in wpf defined as follow:

  <TextBox Grid.Column="4" Grid.Row="1" x:Name="InputDirectory" Margin="2" Background="Gray"/>

when I run application, it doesn't show caret, if I remove background colour or change it to other colours ( I tested white, black and blue) the caret appears.

How can I make sure that caret appears when background is Gray?

回答1:

Try CaretBrush="Tomato" the color used by the CaretIndicator might be the same as the Background currently.

So say:

<TextBox x:Name="InputDirectory"
          Grid.Row="1"
          Grid.Column="4"
          Margin="2"
          Background="Gray"
          CaretBrush="Tomato" />

Tomato is just an example ofc. Pick a color with enough of a difference to your background to make it presentable.
