Maybe Off Topic, but I am curious...

I have created a few HtmlHelper extension methods that we use is different projects at my company, but they've usually been single level type of method calls, with a variable list of parameters.  But how does Kendo create the HTML Helpers such as those found in the Telerik MVC collection, with nested method calls?

For example, I've easily create a razor helper that parses a session variable for Claim data, and return the appropriate claim value based on the type.  Such as 

@{
    ViewBag.Title = "Vensure.Dashboard.App";

    string FullName = Html.GetClaimValue("fullname");
    bool isAdmin = Html.GetClaimValue("app-roles").Contains("admin");
}

 

But the Kendo components typically have multiple methods extending the initial method.  Such as:

@(Html.Kendo().DropDownList()
        .Name("availableClients")
        .DataTextField("ClientName")
        .DataValueField("ClientId")
        .DataSource(ds => ds.Read("GetClientList", "Mapping"))
        .Template("<span class=\"k-state-default\">#: data.ClientId # - #: data.ClientName #</span>")
        .ValueTemplate("<span class=\"selected-value\">#:data.ClientId# - #:data.ClientName#</span>")
        .HtmlAttributes(new { style = "width: 100%" })
        .Events(e => e.Change("clientChange"))
        .OptionLabel(" -- Select Client --")
        .Height(400)
    )

 

I'm just curious as to what the HtmlHelper extension code looks like to support the .Method().OtherMethod().YetAnotherMethod() nested syntax...

Never mind.. after giving it some more thought, the answer dawned on me... it's not really as mysterious as I thought...
