ComboBox styles and templates

[Sergiy]

Hello, I want to change Combobox style ( for instance simple changes of borderbrush, see attached file please).
I tried to change some value of colors in templates, but there is no any result.

Could you explain me step-by-step how can I change borderbrush (of cause separate color when control is enabled and disabled)?
Thank You

Hello Sergiy,

To change the BorderBrush and MouseOver color of RadComboBox, you need to modify the style applied on RadToggleButton(x:Name=PART_DropDownButton). Inside it you can define the BorderBrush you wish to apply on your RadComboBox. In the attached project it is

<Style x:Key="CustomNonEditableComboToggleButtonStyle" TargetType="telerik:RadToggleButton" BasedOn="{StaticResource NonEditableComboToggleButtonStyle}">
    <Setter Property="BorderBrush" Value="{StaticResource AccentBrush}" />
    <Setter Property="Template" Value="{StaticResource CustomNonEditableComboToggleButtonControlTemplate}" />
</Style>

CustomNonEditableComboToggleButtonControlTemplate is responsible for rendering mouse over brushes, pressed and selection brushes. Inside it search for

<Border x:Name="ToggleButtonBackgroundChecked" Grid.ColumnSpan="2" Background="{StaticResource AccentBrush}" Visibility="Collapsed" />

and modify the background color with the color of your choice. 

If you wish to make modification on BorderBrush in Focus state you should modify the Border with name x:Name="FocusVisual" as well.

Please, find attached an illustrative sample, using Implicit Styles.
Hope it helps.

All the best,

Hello Sergui,

The provided sample project uses Implicit Styles in order to modify the style of RadComboBox - thus the style should be applied implicitly to all RadComboBoxes inside the project, so everything should work as expected. Please, check the following article from our help documentation that provides more detailed information about the Implicit Styles:
http://docs.telerik.com/devtools/wpf/styling-and-appearance/styling-apperance-implicit-styles-overview.html

Hopes this helps.
