Clipboard

Tip

This article covers Uno-specific information for Clipboard. For a full description of the feature and instructions on using it, see Copy and paste.

• The Windows.ApplicationModel.DataTransfer.Clipboard class allows you to copy content from your application, and paste the content into your application.

Using Clipboard with Uno

• SetContent and GetContent APIs currently support textual data on all platforms. On Android, they also support URI and HTML formats, but the clipboard can hold only one item. Setting multiple items at once does not work reliably.
• ContentChanged event can observe clipboard changes only when the application is in the foreground. On macOS, the ContentChanged event checks for clipboard changes by polling the current NSPasteboard change count in 1-second intervals. The polling starts only after the first subscriber attaches to the ContentChanged event and stops after the last subscriber unsubscribes.
• Flush operation has an empty implementation. In contrast to WinUI, on other platforms, data automatically remains in the clipboard even after the application is closed.

Examples

Copying text to clipboard

var dataPackage = new DataPackage();
dataPackage.SetText("Hello, clipboard");
Clipboard.SetContent(dataPackage);

Pasting text from the clipboard

var content = Clipboard.GetContent();
var text = await content.GetTextAsync();

Observing clipboard changes

Clipboard.ContentChanged += Clipboard_ContentChanged;

private void Clipboard_ContentChanged(object sender, object e)
{
    // ...
}
