How to change tab menu panel color?

[Psyduck]

Hello.

I want the color outside the tab menu (button) to be transparent. (The image is gray)

How do I customize it?

<telerik:RadTabControl  SelectedIndex="0"
                    VerticalAlignment="Stretch"
                    TabStripPlacement="Top"
                    BorderBrush="Blue"
                    Background="Red"
                    BorderThickness="1"
                    />

 

Thanks.

I think there is not enough explanation, so I will leave it again in detail.

It refers to the dark gray background above the Category and Type buttons. (A little margin on the button)

The menu button has nothing to do with it.

Hello KIM,

If I understand your requirement properly you want to make the background behind the tabs transparent, instead of using the default dark gray color. If this is the case, then you can set the HeaderBackground property of RadTabControl.

<telerik:RadTabControl HeaderBackground="Transparent">

Can you please give this approach a try and let me if it helps?

Hello.

Thank you. I checked using it.

In a visualstudio designer, it is clearly visible on the screen in a transparent color.

But when run, it still looks dark gray. What is the problem?

I'm using Noxaml Windows7 Themes. (v 2020.3.1221.45)

Hello KIM,

I've tested this, but I wasn't able to reproduce the issue. Can you check the attached project and let me know if I am missing anything?
