Dealing with selection changed in Xamarin Segmented Control (SfSegmentedControl)

18 May 20211 minute to read

The selection changed event occurs when there is a change from one segment item to another in the segmented control. It can be handled by two ways.

User interface

When users navigate from one item to another, selection is changed, so that the SelectedIndex value is updated to the new index of the item. The segmented control provides the SelectionChanged event, which is triggered when the selection is changed with the SelectionChangedEventArgs.

Index - Gets the current index value of the selected item.

<buttons:SfSegmentedControl x:Name = "segmentedControl" SelectionChanged="Handle_SelectionChanged"/>
segmentedControl.SelectionChanged += Handle_SelectionChanged;
void Handle_SelectionChanged(object sender, SelectionChangedEventArgs e)
       segmentedControl.BorderColor = UIColor.Red;

Selected Index through programmatically.

Users can set the default value programmatically for the selection to be placed. The selection is updated based on the index value given for the SelectedIndex.

<buttons:SfSegmentedControl SelectedIndex="2"/>
segmentedControl.SelectedIndex = 2;
