Hi,
You should register for the CheckBox's Checked event in the UserControl. And in the UserControl you should also create an API and call the Click event. So, When the CheckBox's Checked event is fired, the UserControl can listens
for it and fires this Click event. A simple example below you can refer to:
UserControl XAML:
<UserControl
x:Class="Usercontrolevent.MyUserControl1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:Usercontrolevent"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
d:DesignHeight="300"
d:DesignWidth="400" x:Name="mycontrol">
<UserControl.Resources>
<DataTemplate x:Key="AllSubjectsHeaderTemplate">
<Border BorderBrush="#FF677E7B"
BorderThickness="0,0,0,1"
Background="#FF534C4C">
<StackPanel Orientation="Horizontal">
<CheckBox x:Name="checkBox"
HorizontalAlignment="Left"
Margin="10"
VerticalAlignment="Top"
IsChecked="{Binding IsChecked}"
Width="27" Checked="checkBox_Checked" />
</StackPanel>
</Border>
</DataTemplate>
</UserControl.Resources>
<Grid>
<ListView ItemTemplate="{Binding Source={StaticResource AllSubjectsHeaderTemplate}}" DataContext="{Binding DataContext,ElementName=mycontrol}" ItemsSource="{Binding}"></ListView>
</Grid>
</UserControl>
UserControl.cs:
public sealed partial class MyUserControl1 : UserControl
{
public MyUserControl1()
{
this.InitializeComponent();
}
public static readonly DependencyProperty ItemTemplateProperty =
DependencyProperty.Register(
"ItemTemplate",
typeof(String),
typeof(MyUserControl1), null
);
public DataTemplate ItemTemplate
{
get { return (DataTemplate)GetValue(ItemTemplateProperty); }
set { SetValue(ItemTemplateProperty, (DataTemplate)value); }
}
public static readonly DependencyProperty ItemsSourceProperty =
DependencyProperty.Register(
"ItemsSource ",
typeof(object),
typeof(MyUserControl1), null
);
public object ItemsSource
{
get { return (object)GetValue(ItemTemplateProperty); }
set { SetValue(ItemTemplateProperty, (object)value); }
}
public event EventHandler Onchecked;
private void checkBox_Checked(object sender, RoutedEventArgs e)
{
Onchecked(this,null);
}
}
MainPage XAML:
<Page.Resources>
<CollectionViewSource x:Name="cvs1" />
</Page.Resources>
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<local:MyUserControl1 DataContext="{StaticResource cvs1}" ItemsSource="{Binding}" Onchecked="Checkevent"></local:MyUserControl1>
</Grid>
MainPage.cs:
public MainPage()
{
this.InitializeComponent();
ObservableCollection<Test> test = new ObservableCollection<Test>();
test.Add(new Test { IsChecked = true });
test.Add(new Test { IsChecked = false });
test.Add(new Test { IsChecked = true });
test.Add(new Test { IsChecked = false });
cvs1.Source = test;
}
public void Checkevent(object sender,EventArgs args)
{
}
}
public class Test
{
public bool IsChecked { get; set; }
}
