Unable to create WPF ComboBox for mouse

Question

Does anyone know how to style the WPF ComboBox background property when the mouse hangs over it?

I can not get rid of the blue-ish button, similar to the background with ComboBox.

Answer 1

He will not work. Due to the default control template for ComboBox. You may need to override the default template for this behavior. Take a look

You can style it like anything else:

<Style TargetType="{x:Type ComboBox}" x:Key="HoverBox"> <Style.Triggers> <Trigger Property="IsMouseOver" Value="True"> <Setter Property="Background" Value="Blue" /> </Trigger> </Style.Triggers> </Style> 

using:

 <ComboBox Style="{StaticResource HoverBox}" ... /> 

And at the top of your UserControl / Window you should put a style:

 <UserControl...> <UserControl.Resources> <Style TargetType="{x:Type ComboBox}" x:Key="HoverBox"> <Style.Triggers> <Trigger Property="IsMouseOver" Value="True"> <Setter Property="Background" Value="Blue" /> </Trigger> </Style.Triggers> </Style> </UserControl.Resources> [CONTENT HERE] </UserControl>
