.NET MAUI SmartPasteButton Events

Updated on Apr 16, 2026

The .NET MAUI SmartPasteButton exposes the following event:

SmartPasteRequest—Raised when the RadSmartPasteButton initiates a smart paste operation. The SmartPasteRequest event handler receives two parameters:
- The sender argument which is of type RadSmartPasteButton.
- A SmartPasteButtonRequestContext object which contains the clipboard content, fields, a cancellation token, and methods to signal the result of the AI request.

Using the SmartPasteRequest Event

The following example demonstrates how to use the SmartPasteRequest event.

1. Define the button in XAML:

XAML

<telerik:RadSmartPasteButton Provider="{x:Reference dataForm}"
                             SmartPasteRequest="OnSmartPasteRequest" />

2. Add the DataForm control to your page. The SmartPasteButton is designed to work with the DataForm control, allowing you to populate form fields with structured data extracted from unstructured text. By integrating the SmartPasteButton with the DataForm, you can enhance the user experience and streamline data entry processes within your application.

XAML

<telerik:RadDataForm x:Name="dataForm"
                     AutoGenerateItems="False" 
                     Grid.Row="1">
    <telerik:RadDataForm.BindingContext>
        <local:Profile />
    </telerik:RadDataForm.BindingContext>
    <telerik:DataFormRadEntryEditor PropertyName="Name" />
    <telerik:DataFormRadEmailMaskedEditor PropertyName="Email" />
    <telerik:DataFormRadEntryEditor PropertyName="JobTitle" />
    <telerik:DataFormRadEntryEditor PropertyName="Address" />
</telerik:RadDataForm>

3. Text from the clipboard is used for the smart paste operation.

XAML

<telerik:RadTemplatedButton Content="Copy To Clipboard"
                            Clicked="OnCopyFromClipboardClicked"/>

4. Add the telerik namespace:

XAML

xmlns:telerik="http://schemas.telerik.com/2022/xaml/maui"

5. The copy button's Clicked event handler:

private async void OnCopyFromClipboardClicked(object sender, System.EventArgs e)
{
    if (!string.IsNullOrEmpty(this.label.Text))
    {
        await Clipboard.SetTextAsync(this.label.Text);
    }
}

6. The SmartPasteRequest event handler:

private async void OnSmartPasteRequest(object sender, SmartPasteButtonRequestContext e)
{
    try
    {
        var request = new { Content = e.Content, FormFields = e.Fields };
        var httpResponse = await new HttpClient().PostAsJsonAsync(
            "https://demos.telerik.com/service/v2/ai/smartpaste/smartpaste",
            request,
            e.CancellationToken);
        httpResponse.EnsureSuccessStatusCode();

        var response = await httpResponse.Content.ReadFromJsonAsync<SmartPasteResponse>(e.CancellationToken);
        e.SetResponse(response.FieldValues);
    }
    catch (OperationCanceledException)
    {
        e.Cancel();
    }
    catch (Exception ex)
    {
        e.SetError(ex);
    }
}

This is the result:

.NET MAUI SmartPasteButton Event

The SmartPasteButton examples in the SDKBrowser Demo Application use a Telerik-hosted AI service for demonstration purposes only.

To use the smart paste functionality in your application, you must configure your own AI service.

How to do that is described in the Configuration article.

For a runnable example demonstrating the SmartPasteButton SmartPasteRequest event, see the SDKBrowser Demo Application and go to the SmartPasteButton > Getting Started category.
