Getting Started with .NET MAUI Popup control

This section guides you through setting up and configuring a Popup in your .NET MAUI application. Follow the steps below to add a basic Popup to your project.

To quickly get started with the .NET MAUI Popup, watch this video:

Prerequisites

Before proceeding, ensure the following are in place:

Install .NET 8 SDK or later.
Set up a .NET MAUI environment with Visual Studio 2022 (v17.8 or later).

Step 1: Create a .NET MAUI project

Go to File > New > Project and choose the .NET MAUI App template.
Name the project and choose a location. Then, click Next.
Select the .NET framework version and click Create.

In Solution Explorer, right-click the project and choose Manage NuGet Packages.
Search for Syncfusion.Maui.Popup and install the latest version.
Ensure the necessary dependencies are installed correctly, and the project is restored.

Step 3: Register the handler

The Syncfusion.Maui.Core is a dependent package for all Syncfusion controls of .NET MAUI. In the MauiProgram.cs file, register the handler for Syncfusion core.

MauiProgram.cs
using Microsoft.Maui.Controls.Hosting;
using Microsoft.Maui.Controls.Xaml;
using Microsoft.Maui.Hosting;
using Syncfusion.Maui.Core.Hosting;

namespace GettingStarted
{
    public class MauiProgram 
    {
        public static MauiApp CreateMauiApp()
        {
            var builder = MauiApp.CreateBuilder();
            builder
                .UseMauiApp<App>()
                .ConfigureFonts(fonts =>
                {
                    fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
                });

            builder.ConfigureSyncfusionCore();
            return builder.Build();
        }
    }
}

To initialize the control, import the Syncfusion.Maui.Popup namespace into your code.
Initialize SfPopup.

MainPage.xaml
MainPage.xaml.cs
<ContentPage   
    . . .
    xmlns:syncfusion="clr-namespace:Syncfusion.Maui.Popup;assembly=Syncfusion.Maui.Popup">

    <syncfusion:SfPopup />
</ContentPage>
using Syncfusion.Maui.Popup;
. . .

public partial class MainPage : ContentPage
{
    public MainPage()
    {
        InitializeComponent();
        SfPopup popup = new SfPopup();
    }
}

Display a popup over your view by calling the Show method.

Refer to the following code example for displaying popup using Button’s Click event.

    public partial class MainPage : ContentPage
    {
        public MainPage()
        {
            InitializeComponent();
        }

        private void ClickToShowPopup_Clicked(object sender, EventArgs e)
        {
            popup.Show();

Ensure the necessary dependencies are installed correctly, and the project is restored. If not, Open the Terminal in Rider and manually run: dotnet restore

Step 3: Register the handler

The Syncfusion.Maui.Core is a dependent package for all Syncfusion controls of .NET MAUI. In the MauiProgram.cs file, register the handler for Syncfusion core.

MauiProgram.cs
using Microsoft.Maui.Controls.Hosting;
using Microsoft.Maui.Controls.Xaml;
using Microsoft.Maui.Hosting;
using Syncfusion.Maui.Core.Hosting;

namespace GettingStarted
{
    public class MauiProgram 
    {
        public static MauiApp CreateMauiApp()
        {
            var builder = MauiApp.CreateBuilder();
            builder
                .UseMauiApp<App>()
                .ConfigureFonts(fonts =>
                {
                    fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
                });

            builder.ConfigureSyncfusionCore();
            return builder.Build();
        }
    }
}

To initialize the control, import the Syncfusion.Maui.Popup namespace into your code.
Initialize SfPopup.

MainPage.xaml
MainPage.xaml.cs
<ContentPage   
    . . .
    xmlns:syncfusion="clr-namespace:Syncfusion.Maui.Popup;assembly=Syncfusion.Maui.Popup">

    <syncfusion:SfPopup />
</ContentPage>
using Syncfusion.Maui.Popup;
. . .

public partial class MainPage : ContentPage
{
    public MainPage()
    {
        InitializeComponent();
        SfPopup popup = new SfPopup();
    }
}

To close the popup programmatically, you can call either the Dismiss method or set the IsOpen property to false.

Refer to the following code example for dismissing popup.

MainPage.xaml.cs
private void ClickToDismissPopup_Clicked(object sender, EventArgs e)
    {
        // Dismiss SfPopup from the view.
        sfPopup.Dismiss();

        // Or
        sfPopup.IsOpen = false;
    }

Customize positioning

The .NET MAUI Popup (SfPopup) allows showing the popup content at various positions.

The following list of options is available to position the SfPopup in the desired position:

Center Positioning: Use the IsOpen property or Show method to display the SfPopup at the center.
Absolute Positioning: Use the Show(x-position, y-position) to display the SfPopup at the specified X and y position.
Relative Positioning: Use the ShowRelativeToView(View, RelativePosition) to display the SfPopup at any of the 8 positions relative to the specified view.
Absolute relative positioning: Use the ShowRelativeToView(View, RelativePosition,x position,y position) to display the SfPopup at an absolute x,y coordinate from the relative position of the specified view.

Customizing layouts

By default, choose a layout from the following available layouts in the SfPopup by using the AppearanceMode property.

OneButton: Shows the SfPopup with one button in the footer view. This is the default value.
TwoButton: Shows the SfPopup with two buttons in the footer view.

Also, customize the entire popup view by loading the templates or custom views for the header, body, and footer.

Refer to the following code example for displaying popup with appearance mode.

               Clicked="ClickToShowPopup_Clicked" />
        <syncfusion:SfPopup x:Name="popup"  ShowFooter="True" AppearanceMode="TwoButton"/>
     </StackLayout>
</ContentPage>
using Syncfusion.Maui.Popup;

namespace GettingStarted
{
    public partial class MainPage : ContentPage
    {
        SfPopup popup;

        public MainPage()
        {
            InitializeComponent();
            popup = new SfPopup();
            popup.ShowFooter = true;
            popup.AppearanceMode = Syncfusion.Maui.Popup.PopupButtonAppearanceMode.TwoButton;
        }

        private void ClickToShowPopup_Clicked(object sender, EventArgs e)
        {
            popup.Show();
        }
    }
}
