Hi,

I have this code in the partial view:

   <button class="stackedContent default" href="@item.Url" title="@item.Title" id="TestBtn" onclick="@UmbClientMgr.openModalWindow("mypage.aspx", "some title", true, 800, 600);">

and I'm getting error Compiler Error Message: CS0103: The name 'UmbClientMgr' does not exist in the current context

In the master page in the head I have the following links:

 <script src="https://code.jquery.com/jquery-1.12.4.js"></script>
    <link rel="stylesheet" href="https://code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css" />
    <script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
<script type="text/javascript" src="umbraco_client/Application/NamespaceManager.js"></script>
<script type="text/javascript" src="umbraco_client/Application/UmbracoApplicationActions.js"></script>
<script type="text/javascript" src="umbraco_client/Application/UmbracoUtils.js"></script>
<script type="text/javascript" src="umbraco_client/Application/HistoryManager.js"></script>
<script type="text/javascript" src="umbraco_client/Application/UmbracoClientManager.js"></script>

and before the end of the body i have the following scripts:

<script src="https://code.jquery.com/jquery-3.3.1.min.js"  crossorigin="anonymous"></script>

    <script src="https://ajax.aspnetcdn.com/ajax/jquery.validate/1.13.1/jquery.validate.min.js"></script>
    <script src="https://ajax.aspnetcdn.com/ajax/mvc/5.2.3/jquery.validate.unobtrusive.min.js"></script>
    <script src=" ~/scripts/script.js"></script>

Am I missing some reference?

Please advise how do I make my code work
