How to reveal a back layer based on a gesture in a Xamarin.Forms application

Platform: Xamarin.Forms |
Control: SfBackdropPage

This section explains how to programmatically open and close FrontLayer of SfBackdropPage in Xamarin.Forms.

Refer to this Getting Started documentation, to create a simple sample with BackDropPage control.

Consider the below use case of revealing back layer content of SfBackdropPage based on the button click event in a Xamarin.Forms application.


This can be achieved by enabling IsBackLayerRevealed property of SfBackdropPage as shown in below code snippet


             xmlns:backdrop="clr-        namespace:Syncfusion.XForms.Backdrop;assembly=Syncfusion.SfBackdrop.XForms"
        <backdrop:BackdropBackLayer >
                <ListView HeightRequest="250">
                    <x:Array Type="{x:Type x:String}">
                        <x:String>01 JAN : New Year</x:String>
                        <x:String>16 JAN : Release Day</x:String>
                        <x:String>10 APR : Good Friday</x:String>
                        <x:String>25 DEC : Christmas</x:String>
            <Grid >
                <Label Text="Upcoming Holidays"/>
                <Button Text="&#x1F5D3;" Grid.Column="1" HorizontalOptions="End"
                        Clicked="Button_Clicked" BackgroundColor="Transparent" />


public partial class Drop : SfBackdropPage{  private void Button_Clicked(object sender, EventArgs e)
            IsBackLayerRevealed = true;



By default, IsBackLayerRevealed property is set as false.
