Hello Y B,
control is designed to display HTML content in Silverlight based page and it best works in combination with our RadWindow
control. However, you have to take a couple of steps before defining the RadHtmlPlaceholder
in XAML. You have to set a windowless
mode to the start page of your web project (where you host your Silverlight page). Take a look at this article
for more information.
Please keep in mind that you have to escape the quotes (e.g. "") in code-behind as demonstrated in the attached project. Take a look at it and let me know if it works for you.
All the best,
Pavel R. Pavlov
