如何从后面的代码更改列表框项目字体颜色

Question

I have tried to access ListBox items properties like this:

mylistBox.Items[0] 

and then to set foreground property but for unknow to me reason i cant access it this way. Can i even do this using code behind - and if yes - how?

Implement ItemTemplate and bind your Brush to Foreground property.

You should implement INotifyPropertyChanged in your binding object and notify on MyColorBrush value change.

<ListBox ItemsSource="{Binding MyItems}">
    <ListBox.ItemTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding MyText}" Foreground="{Binding MyColorBrush}"/>
        </DataTemplate>
    </ListBox.ItemTemplate>
</ListBox>
