【问题描述】:
我对使用 WPF 和 C# 进行编程非常陌生,我对自动检查列表框中所有复选框的可能性有疑问。我正在为 Autodesk Revit 开发一个插件,在列表框中列出了所有房间的名称后,我想使用“全部检查”按钮来检查它们
我已经阅读了at this page 的帖子,但我仍然无法让它工作。有人可以帮我写代码吗?
这是我所做的:
XAML:
<ListBox x:Name='roomlist'
SelectionMode='Multiple'>
<ListBox.ItemTemplate>
<DataTemplate>
<CheckBox IsChecked='{Binding IsChecked}'
Content="{Binding}" />
</DataTemplate>
</ListBox.ItemTemplate>
<ListBox.InputBindings>
<KeyBinding Command="ApplicationCommands.SelectAll"
Modifiers="Ctrl"
Key="A" />
</ListBox.InputBindings>
<ListBox.CommandBindings>
<CommandBinding Command="ApplicationCommands.SelectAll" />
</ListBox.CommandBindings>
</ListBox>
C#
public partial class RoomsDistance_Form : Window
{
UIDocument _uidoc;
Document _doc;
public RoomsDistance_Form(Document doc, UIDocument uidoc)
{
InitializeComponent();
FilteredElementCollector collector = new FilteredElementCollector(doc)
.WhereElementIsNotElementType()
.OfCategory(BuiltInCategory.OST_Rooms);
List<String> myRooms = new List<String>();
foreach (var c in collector)
{
myRooms.Add(c.Name);
}
myRooms.Sort();
roomlist.ItemsSource = myRooms;
}
private void checkAllBtn_Click(object sender, RoutedEventArgs e)
{
foreach (CheckBox item in roomlist.Items.OfType<CheckBox>())
{
item.IsChecked = true;
}
}
public class Authority : INotifyPropertyChanged
{
private bool isChecked;
public bool IsChecked
{
get { return isChecked; }
set
{
isChecked = value;
NotifyPropertyChanged();
}
}
public event PropertyChangedEventHandler PropertyChanged;
private void NotifyPropertyChanged(string propertyName = "")
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
}
}
}
}
非常感谢您的帮助!
