我正在制作带有MVVM模式的WPF应用程序。
是我多次单击一个按钮,如果单击“子按钮”,则会显示带有许多选项卡的子窗口。
标签计数与点击次数相同。
但是我想在一个选项卡中包含项目。
点击次数并不总是一样。
应该如何编辑我的代码?
//视图
<Grid>
<Button Content="CountUp" HorizontalAlignment="Left" Height="76" Margin="72,57,0,0" VerticalAlignment="Top" Width="135" Click="OnClickCountUp"/>
<Button Content="OpenSubWindow" HorizontalAlignment="Left" Height="74" Margin="269,202,0,0" VerticalAlignment="Top" Width="123" Click="OnClicOpenSubWindow"/>
<Label Content="Count : " HorizontalAlignment="Left" Height="28" Margin="254,73,0,0" VerticalAlignment="Top" Width="53"/>
<Label Content="{Binding CountVal}" HorizontalAlignment="Left" Height="28" Margin="307,73,0,0" VerticalAlignment="Top" Width="67"/>
</Grid>
// ViewModel
public class MainViewModel : INotifyPropertyChanged
{
private string count;
public string CountVal
{
get { return count; }
set
{
count = value;
NotifyPropertyChanged("CountVal");
}
}
public ObservableCollection<TabItemData> TabItems { get; set; } = new ObservableCollection<TabItemData>();
public event PropertyChangedEventHandler PropertyChanged;
private void NotifyPropertyChanged(String info)
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(info));
}
}
}
public class TabItemData
{
public string Header { get; set; }
public ObservableCollection<CheckBox> Content { get; set; }
}
//隐藏代码
public partial class MainWindow : Window
{
private MainViewModel mViewmodel;
int count = 0;
public MainWindow()
{
InitializeComponent();
mViewmodel = new MainViewModel();
this.DataContext = mViewmodel;
}
private void OnClicOpenSubWindow(object sender, RoutedEventArgs e)
{
Window1 window1 = new Window1(mViewmodel);
window1.Show();
}
private void OnClickCountUp(object sender, RoutedEventArgs e)
{
count++;
ObservableCollection<CheckBox> items = new ObservableCollection<CheckBox>();
for (int i = 0; i <= count; i++)
{
CheckBox checkBox = new CheckBox();
checkBox.IsChecked = false;
checkBox.Content = count.ToString();
items.Add(checkBox);
}
mViewmodel.CountVal = count.ToString();
mViewmodel.TabItems.Add(new TabItemData() { Header = count.ToString(), Content = items });
}
}
// SubWindow的视图
<Grid>
<TabControl ItemsSource="{Binding TabItems}">
<TabControl.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Header}" />
</DataTemplate>
</TabControl.ItemTemplate>
<TabControl.ContentTemplate>
<DataTemplate>
<CheckBox Content="{Binding Content}" />
</DataTemplate>
</TabControl.ContentTemplate>
</TabControl>
</Grid>
// SubWindow的代码隐藏
public partial class Window1 : Window
{
public Window1(MainViewModel pMainViewModel)
{
InitializeComponent();
this.DataContext = pMainViewModel;
}
}
还有补品。
@我想使用复选框作为“选项卡”中的项目。所以我不想改变。
@如果可以的话,我想每5个项目添加一个标签。如果您提供该代码,我会感到非常高兴。 (例如,page1包含item1、2、3、4和5。page2包含item6、7 ...,依此类推。)
