Asp.net mvc having multiselect with the listbox

Populate the Listbox with MultiSelect.
Controller:
  public ActionResult Create()
  { 
     var Degree=DegreeRepository.GetAllDegree();      
     ViewData["Degree"] = new MultiSelectList(Degree, "DegreeId", "DegreeName");
     return View(); 
  }

Here I want to mention if you want the single selection for the Listbox you can use SelectList as I mentioned here

View
<%: Html.ListBoxFor(model => model.DegreeId, ViewData["Degree"] as MultiSelectList) %>

Population and then selection of item in the dropdownList. 

Controller:

  public ActionResult Edit(int id)
  {       
     var Users=UserRepository.GetUser(id);    
     var Degree=DegreeRepository.GetAllDegree();   
     ViewData["Degree"] = new SectList(Degree,"DegreeId","DegreeName",Users.DegreeId);
     return View();
  }


View:

<%: Html.DropDownListFor(model => model.DegreeId, ViewData["Degree"]) %>
Labels:

Dotnetnuke Inter-module communication (IMC) simplified on version 06.00.02 with c#

Few days ago I developed a module in which I used IMC which really interested me so I decided to write about it. I will try to explain in this post everything that is necessary to make IMC work in the modules. What is Inter Module Communication? As the name implies if you want to communicate or in other words send data from one module to another IMC is one way of doing it. I will be using module A and module B as the names in my post. An Observation: One thing I observed while playing around with it that if module A is on page 1 and module B is on page 2 then the data doesn't get passed. If both the modules are on the same page then only the data get passed. Example: The basic exercise that I will be performing is to take input from the textbox in Module A and display it in label in Module B. 1) You will be using IModuleCommunicator and IModuleListener interfaces to make this communication works. You will be implementing IModuleCommunicator in the class in the modul...
