Replace the [+]-button in TabbedWindow

[Robert]

Is there anyway to replace the [+]-button in TabbedWindow-control, through AdditionalTemplate or similar. I would like to replace it with 

a splitbutton or dropdown menu.

 

(if the answer involves this article https://docs.telerik.com/devtools/wpf/styling-and-appearance/styling-apperance-editing-control-templates, 

please be specific to what file Im supposed to change in, Im new to Telerik)

 

Thanks in advance

I used Telerik.Windows.Controls.Navigation.xaml, copied the control template part and modified it in my own styles.

It works, but kind of messy

 

I still wonder if you could create some sort of stylewith a button and a dropwown and specify that as the "AddButtonStyle" of the TabbedWindow

Hеllo Robert,

There is no built-in API that allows changing the close (x) button of RadTabbedWindow. In order to achieve this, you will need to extract and modify the ControlTemplate of RadTabbedWindow as you already mentioned. More specifically, you can find the AdditionalContent property of the TabbedWindowTabControl in the template and replace its contents. The AdditionalContent contains a panel with few buttons (close, minimize, maximize, restore). You can add your custom button there. Then apply the modified ControlTemplate by setting the Template property of RadTabbedWindow.
