[Zongtian]

Hello,

i am working the radcombobox, but i found the background of the selected  item is not shown, I do not know why, and i did not find its visual state whick controls it.

when i click the combobox, and the items are shown, but i can't see the background of the selected item.

Hi Zongtian,

To customize the selection color inside of RadComboBoxItem, you will have to edit the style of the RadComboBoxItemStyle.   Find the following

<Border x:Name="HighlightVisual" Visibility="Collapsed" CornerRadius="{StaticResource SplitButton_SpanCornerRadius}" BorderThickness="1" BorderBrush="{StaticResource ControlOuterBorder_Highlighted}" Background="{StaticResource ControlBackground_Highlighted}">

and change the Background property to the color of your choice. Please note that the MouseOver state uses the same Border as the selected one.

Hope this helps.

thanks for your reply, and i think i did not explain the problem clear.

my question is that it can not show the background of the element selected when we do the popup of the items of combobox.

for exemple, when i click the button "expander", and it should show the items of combobox, and at the same time we can also see the item seleted which has the different color. But i can not see it.

Any ideas.

Hi Zongtian,

Please excuse me for the misunderstanding. It is hard to tell what is causing the issue only from the screenshot. I've attached a sample project where the RadComboBox shows the selected item when the pop up is opened. Could you check if this is the desired behavior?

If the issue still persists, please send us all RadComboBox XAML modifications which are made. This will be really helpful for tracking down the source of the issue.
