在我的用户控件中,我有一个按钮,单击该按钮会引发自定义路由事件。我试图提高它,但它不会在 MainWindow.xaml 中被触发。
UserControl 中按钮的 Xaml:
<Button x:Name="PART_Add" Content="+" Grid.Column="3" Margin="0,0,0,0" Style="{DynamicResource dTranspButton}" Click="btnAdd_Click"/>
用户控件 C# 代码:
//AddClick Event
public static readonly RoutedEvent AddClickEvent = EventManager.RegisterRoutedEvent("AddClick", RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(dCB_Props));
public event RoutedEventHandler AddClick
{
add { AddHandler(AddClickEvent, value); }
remove { RemoveHandler(AddClickEvent, value); }
}
void RaiseAddClickEvent()
{
RoutedEventArgs newEventArgs = new RoutedEventArgs(dCB_Props.AddClickEvent);
}
protected void OnAddClick()
{
RaiseAddClickEvent();
}
//objects events
private void btnAdd_Click(object sender, System.Windows.RoutedEventArgs e)
{
RaiseAddClickEvent();
}
MainWindow.xaml 中 UserControl 实例的 Xaml 代码:
<local:dCB_Props x:Name="cb1" Margin="41.166,0,36.19,25" VerticalAlignment="Bottom" Height="30" Width="141" AddClick="dCB_Props_AddClick">
<local:dCB_Props.Items>
<ComboBoxItem Content="item1"/>
</local:dCB_Props.Items>
</local:dCB_Props>
应该在 MainWindow.xaml.cs 中触发的 C# 代码:
private void dCB_Props_AddClick(object sender, System.Windows.RoutedEventArgs e)
{
MessageBox.Show("This Works");
}
