Examples

The following example shows how to track changes to the Clipboard. The first code snippet registers a handler for the ContentChanged event. The second code snippet shows the event handler, which displays the text contents of the Clipboard in a TextBlock control.

Clipboard.ContentChanged += new EventHandler<object>(this.TrackClipboardChanges_EventHandler);

private async void TrackClipboardChanges_EventHandler(object sender, object e)
{
    DataPackageView dataPackageView = Clipboard.GetContent();
    if (dataPackageView.Contains(StandardDataFormats.Text))
    {
        String text = await dataPackageView.GetTextAsync();

        // To output the text from this example, you need a TextBlock control
        // with a name of "TextOutput".
        TextOutput.Text = "Clipboard now contains: " + text;
    }
}

Remarks

This event is helpful in situations when your app contains logic that varies depending on the contents on the clipboard. For example, your app might include a Paste button, which is disabled unless the Clipboard contains content.
