Default.aspx.cs

Add the following Namespaces

usingSystem.Collections.Specialized;

This namespace is used for StringCollection

Add the following reference.

· System.DirectoryServices.

· System.DirectoryServices.AccountManagement.

Then u can add the namespace

using System.DirectoryServices;

using System.Configuration;

-----------------------------------------------------------------------------------------------

Write the web.config File as following.

<addkey="DefaultActiveDirectoryServer"value="LDAP://ABC0"/>

</appSettings>

Write the following Code in Page Load

protected void Page_Load(object sender, EventArgs e)

{

foreach (string @group in GetGroups())

{

lstGroups.Items.Add(@group);

}

Write the following Methods in the Page.

public StringCollection GetGroupMembers(string strDomain, string strGroup)

{

StringCollection groupMemebers = new StringCollection();

try

{

DirectoryEntry ent = new DirectoryEntry("LDAP://DC=" + strDomain + ",DC=com");

DirectorySearcher srch = new DirectorySearcher("(" + strGroup + ")");

SearchResultCollection coll = srch.FindAll();

foreach (SearchResult rs in coll)

{

ResultPropertyCollection resultPropColl = rs.Properties;

foreach (Object memberColl in resultPropColl["member"])

{

DirectoryEntry gpMemberEntry = new DirectoryEntry("LDAP://" + memberColl);

System.DirectoryServices.PropertyCollection userProps = gpMemberEntry.Properties;

object obVal = userProps["sAMAccountName"].Value;

if (null != obVal)

{

groupMemebers.Add(obVal.ToString());

}

catch (Exception ex)

{

Trace.Write(ex.Message);

}

return groupMemebers;

}

public static List<string> GetGroups()

{

DirectoryEntry objADAM = default(DirectoryEntry);

// Binding object.

DirectoryEntry objGroupEntry = default(DirectoryEntry);

// Group Results.

DirectorySearcher objSearchADAM = default(DirectorySearcher);

// Search object.

SearchResultCollection objSearchResults = default(SearchResultCollection);

// Results collection.

string strPath = null;

// Binding path.

List<string> result = new List<string>();

string Path = Convert.ToString(ConfigurationManager.AppSettings["DefaultActiveDirectoryServer"]);

// Construct the binding string.

strPath = Path;

//Change to your ADserver

// Get the AD LDS object.

try

{

objADAM = new DirectoryEntry(strPath);

objADAM.RefreshCache();

}

catch (Exception e)

{

throw e;

}

// Get search object, specify filter and scope,

// perform search.

try

{

objSearchADAM = new DirectorySearcher(objADAM);

objSearchADAM.Filter = "(&(objectClass=group))";

objSearchADAM.SearchScope = SearchScope.Subtree;

objSearchResults = objSearchADAM.FindAll();

}

catch (Exception e)

{

throw e;

}

// Enumerate groups

try

{

if (objSearchResults.Count != 0)

{

foreach (SearchResult objResult in objSearchResults)

{

objGroupEntry = objResult.GetDirectoryEntry();

result.Add(objGroupEntry.Name);

}

else

{

throw new Exception("No groups found");

}

catch (Exception e)

{

throw new Exception(e.Message);

}

return result;

}

========================================

protected void lstGroups_SelectedIndexChanged(object sender, EventArgs e)

{

string domainName = Convert.ToString(ConfigurationManager.AppSettings["DomainName"]);

string group = lstGroups.SelectedValue;

StringCollection groupMembers = this.GetGroupMembers(domainName, group);

//Response.Write("The members of"+group +"are");

lstGroupmembers.Items.Clear();

foreach (string strMember in groupMembers)

{

//Response.Write("<br><b>" + strMember + "</b>");

lstGroupmembers.Items.Add(strMember);

}

Cascading DropDown using MVC

And click on Ok Button

And select the project template and click on ok

And go to controller Right click on it and select ADD Controller

Give the name of the controller

Demo Controller.cs

public class DemoController : Controller
{
public ActionResult Index()
{
return View();
}
public ActionResult LoadCountries()
{
List<SelectListItem> li = new List<SelectListItem>();
li.Add(new SelectListItem { Text = "Select", Value = "0" });
li.Add(new SelectListItem { Text = "India", Value = "1" });
li.Add(new SelectListItem { Text = "USA", Value = "2" });
li.Add(new SelectListItem { Text = "UK", Value = "3" });
ViewData["Countries"] = li;
return View();
}
public JsonResult GetCityDetails(string id)
{
List<SelectListItem> cities = new List<SelectListItem>();
switch (id)
{
case "1":
cities.Add(new SelectListItem { Text = "Select", Value = "0" });
cities.Add(new SelectListItem { Text = "Hyderabad", Value = "1" });
cities.Add(new SelectListItem { Text = "Bangalore", Value = "2" });
cities.Add(new SelectListItem { Text = "Mumbai", Value = "3" });
cities.Add(new SelectListItem { Text = "Tirupathi", Value = "4" });
break;
case "2":
break;
case "3":
break;
}
return Json(new SelectList(cities, "Value", "Text"));
}

}

Right Click on LoadCoutries Method, and Select View

LoadCountries.cshtml

@{
ViewBag.Title = "Address Details";
}
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$("#Country").change(function () {
$("#City").empty();
$.ajax({
type: 'POST',
url: '@Url.Action("GetCityDetails")',
dataType: 'json',
data: { id: $("#Country").val() },
success: function (city) {
$.each(city, function (i, city) {
$("#City").append('<option value="' + city.Value + '">' + city.Text + '</option>');
});
},
error: function (ex) {
alert('Error Message.' + ex);
}
});
return false;
})
});
</script>
@using (Html.BeginForm())
{
<div style="color: Purple;">
@Html.Label("Select County")
</div>
<div>
@if (ViewData.ContainsKey("Countries"))
{
@Html.DropDownList("Country", ViewData["Countries"] as List<SelectListItem>, new { style = "width:250px", @class = "dropdown1" })
}
</div>

<div>
@Html.Label("Select City")
</div>
<div class="editor-field">
@Html.DropDownList("City", new SelectList(string.Empty, "Value", "Text"), "Select City", new { style = "width:250px", @class = "dropdown1" })
</div>

public static EmployeeData Instance
{
get
{
return _instance;
}
}

public List<Employee> EmployeeList
