You can use CustomMessageBox from WP toolkit and insert a Textbox in it

TextBox txtBox = new TextBox();
txtBox.Width = 460;
txtBox.Text = selectedChild.Name;
txtBox.HorizontalAlignment = HorizontalAlignment.Center;
txtBox.MaxLength = 14;


CustomMessageBox messageBox = new CustomMessageBox();
messageBox.Caption = "hello";
messageBox.Content = txtBox;
messageBox.LeftButtonContent = "OK";
messageBox.RightButtonContent = "Cancel";
messageBox.IsFullScreen = false;
messageBox.Dismissed += MessageBoxDismissed;
messageBox.Show();

here is the callback

private void MessageBoxDismissed(object sender, DismissedEventArgs e)
{
    CustomMessageBox messageBox = sender as CustomMessageBox;
    if (messageBox != null && e.Result == CustomMessageBoxResult.LeftButton)
    {
        TextBox tb = messageBox.Content as TextBox;
        if (tb != null && !string.IsNullOrEmpty(tb.Text.Trim()))
        {
           //do your stuff
        }
    }
    else
    {
    }
}
