jqxExpander requires the following files:
jqx.base.cssjqxcore.jsjqxexpander.js<script src="~/jqwidgets/jqxexpander.js"></script>
<script src="~/jqwidgets/jqxbuttons.js"></script>
<jqx-expander animation-type="fade" width="500" theme="@ViewData["Theme"]">
    <jqx-expander-header>Header</jqx-expander-header>
    <jqx-expander-body>
       <jqx-button style="margin:5px;" theme="@ViewData["Theme"]">Button 1</jqx-button>
       <jqx-button style="margin:5px;" theme="@ViewData["Theme"]">Button 2</jqx-button>
       <jqx-button style="margin:5px;" theme="@ViewData["Theme"]">Button 3</jqx-button>
   </jqx-expander-body>
</jqx-expander>
        To call a function(method), you need to pass the method name and parameters(if any)
        in the UI component’s instance.
        <script src="~/jqwidgets/jqxexpander.js"></script>
<script src="~/jqwidgets/jqxbuttons.js"></script>
<jqx-expander instance="getInstance()" width="500" theme="@ViewData["Theme"]">
    <jqx-expander-header>Header</jqx-expander-header>
    <jqx-expander-body>
       <jqx-button style="margin:5px;" theme="@ViewData["Theme"]">Button 1</jqx-button>
       <jqx-button style="margin:5px;" theme="@ViewData["Theme"]">Button 2</jqx-button>
       <jqx-button style="margin:5px;" theme="@ViewData["Theme"]">Button 3</jqx-button>
   </jqx-expander-body>
</jqx-expander>
							
@section scripts {								
<script type="text/javascript">									
	function getInstance(instance) {									
		instance["collapse"]();									
	}									
</script>									
}
        To bind to an event of a UI Component, you can use on-event-type syntax. The example
        code below demonstrates how to bind to an event.
        <script src="~/jqwidgets/jqxexpander.js"></script>
<script src="~/jqwidgets/jqxbuttons.js"></script>
<jqx-expander on-collapsing="eventHandler()" width="500" theme="@ViewData["Theme"]">
    <jqx-expander-header>Header</jqx-expander-header>
    <jqx-expander-body>
       <jqx-button style="margin:5px;" theme="@ViewData["Theme"]">Button 1</jqx-button>
       <jqx-button style="margin:5px;" theme="@ViewData["Theme"]">Button 2</jqx-button>
       <jqx-button style="margin:5px;" theme="@ViewData["Theme"]">Button 3</jqx-button>
   </jqx-expander-body>
</jqx-expander>
							
@section scripts {								
<script type="text/javascript">									
	function eventHandler(event) {									
	}									
</script
