Remarks

You can embed a UIElement, such as a Button, directly in content by enclosing it in a InlineUIContainer. An InlineUIContainer cannot host more than one UIElement child. However, the child element hosted by an InlineUIContainer may host children of its own.

Examples

The following code example shows how you can insert an image into a RichTextBox by using InlineUIContainer.

'Insert an image into the RichTextBox
Private Sub btnImage_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)
    Dim container As InlineUIContainer = New InlineUIContainer
    container.Child = MainPage.createImageFromUri(New Uri("/RichNotepad;component/images/Desert.jpg", UriKind.RelativeOrAbsolute), 200, 150)
    rtb.Selection.Insert(container)
    'ReturnFocus()
End Sub

Private Shared Function createImageFromUri(ByVal URI As Uri, ByVal width As Double, ByVal height As Double) As Image
    Dim img As Image = New Image
    img.Stretch = Stretch.Uniform
    img.Width = width
    img.Height = height
    Dim bi As BitmapImage = New BitmapImage(URI)
    img.Source = bi
    img.Tag = bi.UriSource.ToString
    Return img
End Function

//Insert an image into the RichTextBox
private void btnImage_Click(object sender, RoutedEventArgs e)
{
    InlineUIContainer container = new InlineUIContainer();

    container.Child = MainPage.createImageFromUri(new Uri("/RichNotepad;component/images/Desert.jpg", UriKind.RelativeOrAbsolute), 200, 150);

    rtb.Selection.Insert(container);
    ReturnFocus();
}

private static Image createImageFromUri(Uri URI, double width, double height)
{
    Image img = new Image();
    img.Stretch = Stretch.Uniform;
    img.Width = width;
    img.Height = height;
    BitmapImage bi = new BitmapImage(URI);
    img.Source = bi;
    img.Tag = bi.UriSource.ToString();
    return img;
}
