I created menu using MVC5 sitemapmenuprovider, In the xml document I added URL's and Roles of the user and based on role I am displaying the menu.

<mvcSiteMap xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xmlns="http://mvcsitemap.codeplex.com/schemas/MvcSiteMap-File-4.0"
            xsi:schemaLocation="http://mvcsitemap.codeplex.com/schemas/MvcSiteMap-File-4.0 MvcSiteMapSchema.xsd">
  <mvcSiteMapNode url="~/Home/About" title="About" description="" Roles="Admin" visibility="true" ></mvcSiteMapNode>
 
    <mvcSiteMapNode url="~/Home/Contact" title="Contact" description="" Roles="User" visibility="true"></mvcSiteMapNode>

   
    </mvcSiteMapNode>
</mvcSiteMap>

What I have tried:

I want to add other conditions by connecting with database from MVC controller.

but below code from Layout page

@Html.MvcSiteMap().Menu()

does not hitting any controller.

Its directly going to Partial view and displaying the menu

@model MvcSiteMapProvider.Web.Html.Models.SiteMapHelperModel
@using System.Web.Mvc.Html
@using MvcSiteMapProvider.Web.Html.Models

<ul class="siteMap">
    @foreach (var node in Model.Nodes) { 
        <li>@Html.DisplayFor(m => node) 
            @if (node.Children.Any()) {
                @Html.DisplayFor(m => node.Children)
            }
        </li>
    }
</ul>

My question is before going to view is there any possibility to keep conditions in controller and change the node visibility from controller.
