Hi everyone,

I'm very new to Razor so please excuse my stupidity here. I've inherited a decently sized website that uses Umbraco and Razor. So far I'm loving Umbraco but HATING Razor.

We've got a content tree that looks something like this:

Root
|
|-Products
| |
| |-Product A
| |
| |-Product B
|
|-Solutions
| |
| |-Solution A
| |
| |-Solution B
| |
| |-Solution C
| |
| |-Roles
|   |
|   |-Role A
|   |
|   |-Role B
| 
|
etc...

This doesn't seem like the most efficient structure to me, but for now I am going to put up with it.

We have a dropdown menu which currently allows the user to select from either the solutions or the roles. (The roles use the same Content Type as the solutions)

<select id="Solutions" name="Solutions" style="width:225px"  >
    <option value="-1" >Select a solution</option>
    @foreach (var page in Model.AncestorOrSelf(1).Descendants("paSolution").Where("Visible"))
    {
        <option value="@page.Id" >@page.Name</option>                                     
    }
</select>

As a small part of a fairly large update, I have been asked to make this only show Solutions and not Roles. 'No worries' I thought, but roughly 3 hours later I'm starting to realise that there are actually some worries.

I figure that once I can get hold of the Solutions node, it'll (hopefully) be easy to just grab .Children and iterate over those. The trick is that I can't actually get to the Solutions node.

I tried doing this:

var rootNodes = Model.AncestorOrSelf(1);
var solutionsNode = rootNodes.Where(item => item.NodeTypeAlias == "paContent" && item.UrlName.ToLower() == "solutions");

and got the following:

Cannot use a lambda expression as an argument to a dynamically dispatched operation without first casting it to a delegate or expression tree type

So after a bit of Google I revised it to this:

umbraco.MacroEngines.DynamicNode rootNodes = Model.AncestorOrSelf(1);
var solutionsNode = rootNodes.Where(item => item.NodeTypeAlias == "paContent" && item.UrlName.ToLower() == "solutions");

and now I get the following error:

Cannot convert lambda expression to type 'string' because it is not a delegate type

So I think now's probably a good time to admit that I'm out of my depth in Razor/C# and need some help.

I really don't know what to do next. If it helps, I'm using Umbraco v4.7.1.1.

Thanks,

Josh
