How to load data in Xamarin.Forms SfPicker?

You can add a collection to picker at run time by adding it when picker is open on the dialog mode. The following steps explain how to load data in into Xamarin.Forms SfPicker.

Step 1: Add the necessary assemblies in the .NET Standard, Android, iOS, and UWP projects. Refer to this UG documentation to know more about the assemblies required for adding SfPicker to your project.

Step 2: Add a button to ContentPage as mentioned in the following code.

XAML:

<Button 
x:Name="button"
Clicked="button_Clicked"
Text="Open Picker">
</Button>

Step 3: Add the SfPicker control below the button with PickerMode as Dialog as mentioned in the following code.

XAML:

<syncfusion:SfPicker
            x:Name="picker" 
            HeaderText="Select a country"
            PickerMode="Dialog"
            PickerHeight="280"
            PickerWidth="250"
            Opened="picker_Opened"
            WidthRequest="250"
            IsOpen="False"/>  

Step 4: On button click, change the IsOpen property of SfPicker as mentioned in the following code.

C#:

  private void button_Clicked(object sender, EventArgs e)
    {
        picker.IsOpen = true;
    }  

Step 5: On the SfPicker opened event, load items to picker.

C#:

private void picker_Opened(object sender, EventArgs e)
    {
        NameInfo name = new NameInfo();
 
        picker.ItemsSource = name.Names;
    }
