Creating Dynamic Menu Bar C#.Net

Here is the example for the Dynamic Menu creation..
U need to create css for the static and dynamic styles,
Important thing is the menu id , Menu ID should be minimum (maintain around 10 charaters) , I spent lot of time to identify the Issue which created by menu id , I was given over 30+ character which makes effect on total Controls which is available on the page..

private Panel CreateDynamicMenuBar(List<string> Permissions, string GroupName)
    {
        Menu MyMenu = new Menu();
        MyMenu.ID = "menu";
        MyMenu.Orientation = Orientation.Vertical;
        MyMenu.StaticDisplayLevels = 1;
        MyMenu.Width = Unit.Percentage(100);
        MyMenu.StaticMenuStyle.BorderWidth = Unit.Pixel(0);
        MyMenu.StaticMenuItemStyle.HorizontalPadding = Unit.Pixel(0);
        MyMenu.CssClass = "treemenustyle2";
        MyMenu.StaticMenuItemStyle.CssClass = "StaticItem1";
        MyMenu.StaticHoverStyle.CssClass = "StaticHighlight1";
        MyMenu.DynamicMenuStyle.CssClass = "ie8fix";
        MyMenu.DynamicMenuItemStyle.CssClass = "DynamicItem1";
        MyMenu.DynamicHoverStyle.CssClass = "DynamicHighlight1";
        MyMenu.DynamicSelectedStyle.CssClass = "DyanamicSelected1";
        MyMenu.StaticSelectedStyle.CssClass = "StaticSelected1";
        MyMenu.MenuItemClick += new MenuEventHandler(this.Menutasks_SelectedItemChanged);
        MyMenu.Items.Clear();
   
        foreach (var v in Permissions)
        {
            string permissions = v;
            MenuItem item = null;
            item = new MenuItem( permissions );
            item.ToolTip = permissions[1];
            MyMenu.Items.Add(item);
        }
     
        Panel menupannel = new Panel();
        menupannel.Controls.Add(MyMenu);
        return menupannel;
    }

Response.Redirect vs Server.Transfer

Server.Transfer does a server side transfer.

Response.Redirect does a client side redirect - the server informs thebrowser to redirect.
So here's the flow:

Server.Transfer
1. Client Request Page HelloWorld.ASPX2. Server.Transfer -> Server send a different page to the client3. Client Receives Page still thinking it's HelloWorld.ASPX.4. Client's URL (Address bar) remains HelloWorld.ASPX since the page wassent on the server side and the client doesn't know a different page wassent.

Response.Redirect
1. Client Requests Page HelloWorld.ASPX2. Response.Redirect -> Server sends a HTTP header informing that theuser should redirect. 3. Client sees the redirect notice and requestsAnotherPage.ASPX 4. Server sends AnotherPage.ASPX5. Client's URL (address bar) shows AnotherPage.ASPX
Technically speaking, Server.Trasfer is faster since there 1 lessroundtrip, but you lose the URL of the page. Server.Transfer also allowsfor more flexibilty since you can use HTTPContext.Items to passvariables beteen pages

.cs files got corrupted?

If your .cs file got currupted then we have one chance to recover those files.

You need to have the assembly dll related to that currupted file which was build previously.
you need to do Disassembler using .Net Reflector


Solution to recover .cs file 
1. Just Download the .Net Reflector and Install. http://www.reflector.net/
2. Open File -> ' Export Assembly source code'

3. In that Export dialogue show the dll related to corrupted file by 'Browse' option and Click 'Start'

Show any other related dll's if required while processing.

Your files will be Generated in the specified 'Output Directory'

Sorting Alphanumeric

Sorting Alphanumeric:
IComparer interface
public class AlphanumComparatorFast : IComparer
{
    public int Compare(object x, object y)
    {
 string s1 = x as string;
 if (s1 == null)
 {
     return 0;
 }
 string s2 = y as string;
 if (s2 == null)
 {
     return 0;
 }

 int len1 = s1.Length;
 int len2 = s2.Length;
 int marker1 = 0;
 int marker2 = 0;
 while (marker1 < len1 && marker2 < len2)
 {
     char ch1 = s1[marker1];
     char ch2 = s2[marker2];
     char[] space1 = new char[len1];
     int loc1 = 0;
     char[] space2 = new char[len2];
     int loc2 = 0;
     do
     {
  space1[loc1++] = ch1;
  marker1++;

  if (marker1 < len1)
  {
      ch1 = s1[marker1];
  }
  else
  {
      break;
  }
     } while (char.IsDigit(ch1) == char.IsDigit(space1[0]));

     do
     {
  space2[loc2++] = ch2;
  marker2++;

  if (marker2 < len2)
  {
      ch2 = s2[marker2];
  }
  else
  {
      break;
  }
     } while (char.IsDigit(ch2) == char.IsDigit(space2[0]));

     string str1 = new string(space1);
     string str2 = new string(space2);

     int result;

     if (char.IsDigit(space1[0]) && char.IsDigit(space2[0]))
     {
  int thisNumericChunk = int.Parse(str1);
  int thatNumericChunk = int.Parse(str2);
  result = thisNumericChunk.CompareTo(thatNumericChunk);
     }
     else
     {
  result = str1.CompareTo(str2);
     }

     if (result != 0)
     {
  return result;
     }
 }
 return len1 - len2;
    }
}

//Main method

using System;
using System.Collections;

class Program
{
    static void Main()
    {
 string[] highways = new string[]
 {
     "100F",
     "50F",
     "SR100",
     "SR9"
 };
 
 Array.Sort(highways, new AlphanumComparatorFast());
 
 foreach (string h in highways)
 {
     Console.WriteLine(h);
 }
    }

Output:
