ComboBoxItem PointerEntered Event is not fired in UWP?

Question

<Grid>
<ComboBox x:Name="ColorRepresentationComboBox" Margin="0,12,0,0"  Width="120" >
<ComboBoxItem x:Name="HEXComboBoxItem" Content="HEX" PointerPressed="HEXComboBoxItem_PointerPressed"/>
<ComboBoxItem x:Name="HSLComboBoxItem" Content="HSL" PointerPressed="HSLComboBoxItem_PointerPressed"/>
</ComboBox>
   </Grid>



private void HEXComboBoxItem_PointerPressed(object sender, PointerRoutedEventArgs e)
{

}

private void HSLComboBoxItem_PointerPressed(object sender, PointerRoutedEventArgs e)
{

}

PointerEntered Event work properly,but pointerPressed event is not fired.I dont Know why?

Answer 1

In this case, it should be that the PointerPressed event has been specially handled inside the ComboBox .

If you want to capture the click event of ComboBoxItem , you can consider using Tapped event.

<ComboBoxItem x:Name="HEXComboBoxItem" Content="HEX" Tapped="HEXComboBoxItem_Tapped"/>

private void HEXComboBoxItem_Tapped(object sender, TappedRoutedEventArgs e)
{
    Debug.WriteLine("tapped");
}

If you just want to get the selected item after the ComboBox selected item is changed, you can consider using this method:

<ComboBox SelectionChanged="ComboBox_SelectionChanged">
    <ComboBoxItem x:Name="HEXComboBoxItem" Content="HEX" Tapped="HEXComboBoxItem_Tapped"/>
</ComboBox>

private void ComboBox_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    var item = (sender as ComboBox).SelectedItem as ComboBoxItem;
    // do other things...
}

Thanks.

There's an easy solution here . It says:

These events have to be handled not through XAML but thorugh AddHandler method.

SomeButton.AddHandler(PointerPressedEvent, 
    new PointerEventHandler(SomeButton_PointerPressed), true);
