ItemsSource="{Binding CommandsSource , NotifyOnSourceUpdated=True}"
HorizontalAlignment="Left"
ScrollViewer.VerticalScrollBarVisibility="Visible"
VerticalAlignment="Stretch" MinWidth="100">
<ListBox.ItemTemplate>
<DataTemplate>
<DockPanel >
<TextBlock Text="*"/>

<TextBlock Text="{Binding CommandName}"/>
</DockPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
问题是
列表框
仅显示*
字符我通过更改命令项
类解决了这个问题:
public class CommandItem
{
public string CommandName;
public bool IsInTheOtherList;
public Color BGColor
{
get
{
if (IsInTheOtherList)
return Color.FromRgb(0, 0,255);
return Color.FromRgb(255, 255,0);
}
}
}
public class CommandItemClass : PropertyChangedBase
{
private string _commandName;
private bool _isInTheOtherList;
public SolidColorBrush BGColor
{
get
{
if (IsInTheOtherList)
return new SolidColorBrush(Color.FromRgb(0, 0, 255));
return new SolidColorBrush(Color.FromRgb(255, 255, 0));
}
}
public string CommandName
{
get
{
return _commandName;
}
set
{
_commandName = value;
NotifyOfPropertyChange(()=>CommandName);
}
}
public bool IsInTheOtherList
{
get
{
return _isInTheOtherList;
}
set
{
_isInTheOtherList = value;
NotifyOfPropertyChange(() => IsInTheOtherList);
NotifyOfPropertyChange(()=>BGColor);
}
}
}
