问题描述

我做一个WPF并具有计算机上的avaible端口的列表的组合框。我想改变这些项目的颜色

I am doing a WPF and have a comboBox which has a list of the avaible ports on the computer. I want to change the color of these items.

我的组合框是这些：

<ComboBox HorizontalAlignment="Left" Margin="445,0,0,0" VerticalAlignment="Top"     Width="120" Loaded="ComboBoxLoaded" SelectionChanged="ComboBoxSelectionChanged" Grid.Column="1" Background="#849096" Foreground="White"/>

而这些是加载它的方法：

And these is the method to loaded it:

private void ComboBoxLoaded(object sender, RoutedEventArgs e)
    {
        string [] portsList = PrintPorts();

        // get the ComboBox reference
        var comboBox = sender as ComboBox;

        // assign the ItemsSource to the List
        comboBox.ItemsSource = portsList;

        // make the first item selected
        comboBox.SelectedIndex = 0;
    }

我尝试了很多东西，但没有任何工程。有人知道该怎么办呢？谢谢！

I was trying a lot of things but nothing works. Someone knows how to do it? Thanks!!

推荐答案

要更改单个项目的背景颜色，您可以修改 ItemContainerStyle ，是这样的：

To change the background color of the individual items you can change the ItemContainerStyle, something like:

    <ComboBox>
        ...
        <ComboBox.ItemContainerStyle>
            <Style TargetType="{x:Type ComboBoxItem}">
                <Setter Property="Background" Value="Blue" />
            </Style>
        </ComboBox.ItemContainerStyle>
        ...
    </ComboBox>

这将设置背景颜色 ComboBoxItem s到蓝色

This will set the background color on the ComboBoxItems to Blue
