Remarks

The drop-down icon is an icon that appears on the right side of the ComboBoxEdit when the drop-down list is collapsed. Use the IsDropDownIconVisible property to change the visibility of the drop-down icon.

To set a custom image for the drop-down icon, follow the steps below:

1. Add the icon file (for example, icon.svg) to the Resources/Images folder. Make sure that its build action is set to MauiImage.

2. Assign the icon to the DropDownIcon property:

If you want to specify a custom drop-up icon, set the DropDownIcon property to a custom image when the drop-down list is open. To track the drop-down list state, check the value of the IsDropDownOpen property.

The example below shows how to replace the DropDownIcon property value at run time if you use custom styles and triggers:

• XAML

<Style TargetType="dxe:ComboBoxEdit">
  <Setter Property="DropDownIcon" Value="custom_drop_down"/>
  <Style.Triggers>
      <Trigger TargetType="dxe:ComboBoxEdit" Property="IsDropDownOpen" Value="True">
        <Setter Property="DropDownIcon" Value="custom_drop_up"/>
      </Trigger>
  </Style.Triggers>
</Style>
