Closing the DropDown of the ComboBox on Click Outside Its Bounds
Environment

ComboBox for .NET MAUI | 6.6.0 |
Description
To close the DropDown of the ComboBox when the user clicks outside of the component's bounds, you can use a workaround that involves attaching a gesture recognizer to the parent layout or main layout in the page and setting the IsDropDownOpen
property of the ComboBox to false
.
Solution
Follow these steps to implement the workaround:
1. In your XAML code, locate the parent layout or main layout that contains the ComboBox.
2. Add a GestureRecognizer
to the parent layout and subscribe to its Tapped
event. For example:
<VerticalStackLayout>
<VerticalStackLayout.GestureRecognizers>
<TapGestureRecognizer Tapped="TapGestureRecognizer_Tapped"/>
</VerticalStackLayout.GestureRecognizers>
<!-- Other controls and elements -->
</VerticalStackLayout>
3. In the event handler method, set the IsDropDownOpen
property of the ComboBox to false
. This will close the DropDown when someone clicks outside its boundaries. For example:
private void TapGestureRecognizer_Tapped(object sender, TappedEventArgs e)
{
this.comboBox.IsDropDownOpen = false;
}
Notes
- This workaround is applicable to both Android and iOS platforms.
- Make sure to replace
comboBox
with the actual name of your ComboBox control in the event handler method.
