我正在使用wpfToolKit的checkedListbox控件,我想在按下按钮但不起作用时检查列表中的所有复选框。
Xaml
<xctk:CheckListBox Command="{Binding CheckBoxClickedCommand}"
ItemsSource="{Binding ChosenFiles, UpdateSourceTrigger=PropertyChanged}"
DisplayMemberPath="Name"/>
ViewModel
公共ObservableCollection ChosenFiles {get;组; }
模型
public class ChosenFile{
public string FullPath { get; set; }
public string Name { get; set; }
public bool IsChecked { get; set; }
}
当我更改IsChecked属性时,我希望我的checkedListbox更新吗?
答案 0 :(得分:1)
这是您可以怎么做
首先按如下所示重新定义“ ChosenFile”类,以连接INotifyPropertyChanged接口
public class ChosenFile : INotifyPropertyChanged
{
private string _fullPath;
public string FullPath
{
get { return _fullPath; }
set
{
_fullPath = value;
OnPropertyChanged();
}
}
private string _name;
public string Name
{
get { return _name; }
set
{
_name = value;
OnPropertyChanged();
}
}
private bool _isChecked;
public bool IsChecked
{
get { return _isChecked; }
set
{
_isChecked = value;
OnPropertyChanged();
}
}
private void OnPropertyChanged([CallerMemberName] string propName = "")
{
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propName));
}
public event PropertyChangedEventHandler PropertyChanged;
}
Window.xaml
<Button Command="{Binding CheckBoxClickedCommand}" Width="100"> Check All</Button>
<xctk:CheckListBox ItemsSource="{Binding ChosenFiles}" DisplayMemberPath="Name" SelectedMemberPath="IsChecked" />
在后面的代码中,在“ CheckBoxClickedCommand”执行方法上,执行此操作
foreach (var rec in ChosenFiles)
rec.IsChecked = true;
