Department structure treeview passing argument to fetch employees (MVC 4)

I have the following problem: I am making an MVC intranet website for the corporation I'm working for. One part of the job is to make a phonebook - I need a tree like structure of the departments (with depth).
I have a view with two div elements - left (containing the departments, the structure follows below), and a right div which should show all the employees that are working in the selected (clicked) department.
#helper GetTree(List<PhonesClasses.Department> department, int parentID){
foreach(var i in department.Where(a=>a.headDepartmentID.Equals(parentID)))
{
{var childDepartments = department.Where(a => a.headDepartmentID.Equals(i.departmentID)).Count();
if(childDepartments > 0)
{
<li class="haschlid" id="#i.departmentID">
#i.departmentName
<ul class="sub-dep">
#GetTree(department, #i.departmentID)
</ul>
</li>
}
else
{
<li id="#i.departmentID">
#i.departmentName
</li>
}
}
}
The following is the above-mentioned view. As you can see, I had the idea to make a partial view but I'm not sure I'm headed in the right direction.
<div class ="containerStructure">
<div class="leftDivStructure">
#if (Model != null && Model.Count() > 0)
{
<ul class="list" id="deplist">
#Treeview.GetTree(Model, Model.FirstOrDefault().headDepartmentID)
</ul>
}
</div>
<div class="rightDivStructure">
Employee
#*#Html.Partial("_PeopleInDepartment", new {depID = Model.departmentID()})*#
</div>
</div>
My employee and department classes both have DepartmentID fields, so when a department is clicked on in my tree view, a parameter () should be passed to the partial view, or whatever needs to be there to handle the parameter and show the employees. Below is the controller that I think has to fetch the result.
public ActionResult PeopleInDepartment(int depID)
{
List<Person> peopleList = new List<Person>();
peopleList = Persons.GetPersons(depID);
return View(peopleList);
}
For further clarifications please comment!

How to dynamically create several ActionLinks from the Controller in MVC?

I'm using MVC where I have a list of strings that I would like to point to a new page. I'm using Razor and am very new to MVC and cannot seem to find the answer to my question through google.
My list could contain of the following:
"hello"
"goodbye"
"seeya"
I know how to insert strings from the controller to the html page using ViewBag, and I would use the following actionlink if I had a fixed set of strings:
#Html.ActionLink("viewedName", "ChemicalClass", new { mystring = "hello" })
#Html.ActionLink("viewedName", "ChemicalClass", new { mystring = "goodbye" })
#Html.ActionLink("viewedName", "ChemicalClass", new { mystring = "seeya" })
As I understand it, this would generate 3 links that would redirect to the subpage "ChemicalClass", and it would contain the one of the 3 parameters, depending on the link that was clicked.
My quesiton is, how can I do the same, but have the ActionLinks created dynamically, since I won't know how many links are going to be created, nor the content of the strings. My goal is to show these links on the webpage in (preferabely) a list form, e.g.:
<ol>
<li>
hello
</li>
<li>
goodbye
</li>
<li>
seeya
</li>
</ol>
Where each element in the list is a link and not just a string.

Create a view model that stores a collection of links
Model
public class ViewModel
{
public IList<string> Links { get; set; }
}
populate that model in your controller
Controller
public ActionResult Index()
{
var model = new ViewModel
{
Links = new List<string>
{
"Hello",
"Goodbye",
"Seeya"
}
};
return View(model);
}
and finally your view
View
#model MvcApplication1.Models.ViewModel
<ol>
#foreach (var item in Model.Links)
{
<li>
#Html.ActionLink("viewedName", "ChemicalClass", new { mystring = item })
</li>
}
</ol>
Your class holds your collection of strings and razor loops over them to produce your links.

you can use something like this.
<ul>
#foreach (var x in Model)
{
<li>#x.myString </li>
}
</ul>

I have something like this in one of my Views:
#foreach (var item in Model.MyList)
{
<li>
#Html.ActionLink("Select", "ActionName", "Chemical", new {id = item.AdmNum}, new { #class = "label label-info"})
</li>
}

How can I make sure that the newest items added to the list variable gets placed in the top and not in the bottom when it get displayed in html?

I am using MVC + EF
I have a Feed xml file url that gets updated every 7 minute with items, every time a new item gets added I retrieve all the items to a list variable and then I add these varible to my database table. After that I fill a new list variable which is my ViewModel from the database table. Then I declare the ViewModel inside my view which is a .cshtml file and loop throught all of the objects and display them.
How can I make sure that the newest items get placed on the top and not in the bottom?
This is how I display the items inside my cshtml note that I use a ++number so the newest item needs to be 1 and so on.. :
#model Project.Viewmodel.ItemViewModel
#{
int number = 0;
}
}
<div id="news-container">
#foreach (var item in Model.NewsList)
{
<div class="grid">
<div class="number">
<p class="number-data">#(++number)</p>
</div>
<p class="news-title">#(item.Title)</p>
<div class="item-content">
<div class="imgholder">
<img src="#item.Imageurl" />
<p class="news-description">#(item.Description) <br />#(item.PubDate) | Source</p>
</div>
</div>
</div>
}
</div>
This is how I fill the viewmodel which I use inside the .cshtml file to iterate throught and display the items
private void FillProductToModel(ItemViewModel model, News news)
{
var productViewModel = new NewsViewModel
{
Description = news.Description,
NewsId = news.Id,
Title = news.Title,
link = news.Link,
Imageurl = news.Image,
PubDate = news.Date,
};
model.NewsList.Add(productViewModel);
}
Sorry for the paint lol :P
Any kind of help is appreciated

#foreach (var item in Model.NewsList.OrderByDescending(n => n.PubDate)

Create a list to display the contents of a dictionary?

I have a dictionary that i would like to display as a list on my view page. At the moment i can create a list but i cant set a dynamic size or populate it with my dictionary. I would like to do something like a foreach, or if there is a faster just to list function?
Im new to MVC sorry for poor code.
#model Dictionary<string, string>
#{
ViewBag.Title = "Download";
}
<hgroup class="title">
<h1>#ViewBag.Title.</h1>
<h2>#ViewBag.Message</h2>
<br>
#{
var filelist = #Model.ToList();
}
<Div>
<select name="Fileslist" size="5">
<option>Count</option>
<option>text2</option>
<option>text3</option>
<option>text4</option>
<option>text5</option>
</select>
</Div>
</hgroup>

A simple Dictionary to List would be
Dictionary<string, string> myDictionary = new Dictionary<string, string>();
// Add some values in dictionary
var res = myDictionary.Select(x => x.Key + "-" + x.Value).ToList()

You can use #Html.DropDownListFor which supports Dictionary directly.

How do I get the children of an Element in Watin?

Given the following html:
<ul id="search-results">
<li>
<h3>Result 1</h3>
<span class="some-info">Tag line</span>
</li>
<li>
<h3>Result 2</h3>
<span class="some-info">Another bit</span>
</li>
<li>
<h3>Result 2</h3>
<span class="some-info">Another bit</span>
</li>
</ul>
I can get the ul element with:
Element ul = ie.Element(Find.ById("search-results"));
How do I iterate over the children of the search-results?
I've managed to get as far as:
var allListItems = ie.Elements.Filter(e => e.Parent != null && e.Parent.Id == "search-results");
But this doesn't help me assert things about the H3 or span contained within the li's.

*Option1:*Based on your code, you can try something like:
ie.Spans.Filter(Find.ByClass("some-info"))[0...2].PreviousSibling;
you will need to loop over each span.
*Option2:*Based on some suggestions from the Watin mail list (similar to your own answer as well):
IElementContainer elem = (IElementContainer)ie.Element(Find.ById("search-results"));
Then you parse through elem.Element

Current best hack I can think of is:
public static class WatinExtensions
{
public static ElementCollection Children(this Element self)
{
return self.DomContainer.Elements.Filter(e => self.Equals(e.Parent));
}
}
ElementCollection results = ie.Element(Find.ById("search-results")).Children();
// and
foreach(Element li in results)
{
Element info = li.Children().First(e => e.ClassName.Contains("some-info"));
}
It works but surely there is a proper why to do this?
And there is a correct way to do this from the watin mailing list:
In my example:
var searchResults = (IElementContainer) ie.Element(Find.ById("search-results"));
foreach (Element element in searchResults.Elements) {
// can do more here
}
