Looping in Xamarin Picker (SfPicker)

4 Aug 20222 minutes to read

The Looping support is used to automatically navigate the first item to repeat the list of items after reached the last item. Each forward iteration is followed by a backward iteration in the picker control. This can be achieved by EnableLooping property.

EnableLooping

The looping support is achieved by setting the EnableLooping property to true.

XAML

<ContentPage.BindingContext>

<local:ColorInfo />

</ContentPage.BindingContext>

<ContentPage.Content>

<syncfusion:SfPicker

x:Name="picker"

HeaderText="Select a Color"

EnableLooping="True"

ItemsSource="{Binding Colors}" />

</ContentPage.Content>

</ContentPage>

C#

SfPicker picker = new SfPicker();

ColorInfo info = new ColorInfo();

picker.ItemsSource = info.Colors;

// Enable Looping in carousel control
picker.EnableLooping = true;

How to restrict Looping in a particular column of the picker

    OnColumnLoaded="Picker_OnColumnLoaded"/>

        {
          //restrict an Looping in Column 1
           if(e.Column == 1)
