So I am trying to change the style of my combobox in Expression blend.
What I did was create a combobox, and went RightClick > Edit Template > Edit a Copy
And I can change the colors of the combobox, except there is a white border in between the background of the combobox, and the border of the combobox. Here is a screen so you can see:
As you can see, there is a while border between the blue and red. As far as I can tell, the code to change the color of combobox is the following:
<ToggleButton Grid.ColumnSpan="2" IsChecked="{Binding IsDropDownOpen, Mode=TwoWay,
RelativeSource={RelativeSource TemplatedParent}}" Style="{StaticResource
ComboBoxReadonlyToggleButton}" BorderBrush="Red" Background="Blue"/>
But no matter what, there is always a white border. How do i get rid of it?
