if u get this type 'Sys.Extended is undefined ' error in asp.net AjaxControlToolkit latest version on (4.1.7.1005)

use Ajaxtoolkit script manager not <asp:ScriptManager>

Types of state management  

There are two types of state management techniques: client side and server side.

Client side

1. Hidden Field
2. View State
3. Cookies
4. Control State
5. Query Strings

Server side

1. Session
2. Application

Levels of state management 

1. Control level: In ASP.NET, by default controls provide state management automatically.
2. Variable or object level: In ASP.NET, member variables at page level are stateless and thus we need to maintain state explicitly.
3. Single or multiple page level: State management at single as well as multiple page level i.e., managing state between page requests.
4. User level: State should be preserved as long as a user is running the application.
5. Application level: State available for complete application irrespective of the user, i.e., should be available to all users.
6. Application to application level: State management between or among two or more applications.

Client side methods

1. Hidden field

Hidden field is a control provided by ASP.NET which is used to store small amounts of data on the client. It store one value for the variable and it is a preferable way when a variable's value is changed frequently. Hidden field control is not rendered to the client (browser) and it is invisible on the browser. A hidden field travels with every request like a standard control’s value.
Let us see with a simple example how to use a hidden field. These examples increase a value by 1 on every "No Action Button" click. The source of the hidden field control is.

<asp:HiddenField ID="HiddenField1" runat="server"  /> 

2. View state

View state is another client side state management mechanism provided by ASP.NET to store user's data, i.e., sometimes the user needs to preserve data temporarily after a post back, then the view state is the preferred way for doing it. It stores data in the generated HTML using hidden field not on the server.
View State provides page level state management i.e., as long as the user is on the current page, state is available and the user redirects to the next page and the current page state is lost. View State can store any type of data because it is object type but it is preferable not to store a complex type of data due to the need for serialization and deserilization on each post back. View state is enabled by default for all server side controls of ASP.NET with a property EnableviewState set to true.
Let us see how ViewState is used with the help of the following example. In the example we try to save the number of postbacks on button click.

3. Cookies

Cookie is a small text file which is created by the client's browser and also stored on the client hard disk by the browser. It does not use server memory. Generally a cookie is used to identify users.
A cookie is a small file that stores user information. Whenever a user makes a request for a page the first time, the server creates a cookie and sends it to the client along with the requested page and the client browser receives that cookie and stores it on the client machine either permanently or temporarily (persistent or non persistence). The next time the user makes a request for the same site, either the same or another page, the browser checks the existence of the cookie for that site in the folder. If the cookie exists it sends a request with the same cookie, else that request is treated as a new request.

Types of Cookies

1. Persistence Cookie: Cookies which you can set an expiry date time are called persistence cookies. Persistence cookies are permanently stored till the time you set.
Let us see how to create persistence cookies. There are two ways, the first one is: 

Response.Cookies["nameWithPCookies"].Value = "This is A Persistance Cookie";
Response.Cookies["nameWithPCookies"].Expires = DateTime.Now.AddSeconds(10); 

2. Non-Persistence Cookie: Non persistence cookies are not permanently stored on the user client hard disk folder. It maintains user information as long as the user accesses the same browser. When user closes the browser the cookie will be discarded. Non Persistence cookies are useful for public computers.
Let us see how to create a non persistence cookies. There are two ways, the first one is:

Response.Cookies["nameWithNPCookies"].Value = "This is A Non Persistance Cookie";

4. Control State

Control State is another client side state management technique. Whenever we develop a custom control and want to preserve some information, we can use view state but suppose view state is disabled explicitly by the user, the control will not work as expected. For expected results for the control we have to use Control State property. Control state is separate from view state.
How to use control state property: Control state implementation is simple. First override the OnInit() method of the control and add a call for the Page.RegisterRequiresControlState() method with the instance of the control to register. Then override LoadControlState and SaveControlState in order to save the required state information.

Server side

1. Session   

Session management is a very strong technique to maintain state. Generally session is used to store user's information and/or uniquely identify a user (or say browser). The server maintains the state of user information by using a session ID. When users makes a request without a session ID, ASP.NET creates a session ID and sends it with every request and response to the same user.
How to get and set value in Session:

void Session_Start(object sender, EventArgs e)
{

} 

Session["Count"] = Convert.ToInt32(Session["Count"]) + 1;//Set Value to The Session
Label2.Text = Session["Count"].ToString(); //Get Value from the Sesion

There are four session storage mechanisms provided by ASP.NET:

• In Proc mode 
• State Server mode  
• SQL Server mode 
• Custom mode

In Process mode: In proc mode is the default mode 
provided by ASP.NET. 
In this mode, session values are stored in the web server's memory (in 
IIS). 
If there are more than one IIS servers then session values are stored in
 each server separately on which request has been made. Since the 
session values 
are stored in server, 
whenever server is restarted the session values will be lost. 

<configuration>
 <sessionstate mode="InProc" cookieless="false" timeout="10" 
    stateConnectionString="tcpip=127.0.0.1:80808" 
    sqlConnectionString="Data Source=.\SqlDataSource;User ID=userid;Password=password"/>
</configuration> 

In State Server mode: This mode could store session in the web server but out of 
the application pool. But usually if this mode is used there will 
be a separate server for storing sessions, i.e., stateServer. The benefit is that when IIS restarts the session is available. 
It stores session in a separate 
Windows service. For State server session mode, we have to configure it explicitly in the web config file and start the aspnet_state service. 

If you having this problem in IIS 7.x; you can fix this issue with enabling “ASP.NET State Service” from the services. To do so; Follow the bellow steps:
1) Start–> Administrative Tools –> Services
2) Write click over the service shown below and click “start”

<configuration><sessionstate mode="stateserver" cookieless="false" 
   timeout="10"  stateConnectionString="tcpip=127.0.0.1:42424"  
   sqlConnectionString="Data Source=.\SqlDataSource;User ID=userid;Password=password"/> </configuration> 

In SQL Server mode: Session is stored in a SQL Server database. 
This kind of session mode is also separate from IIS, i.e., session 
is available even after restarting the IIS server. This mode is highly secure and reliable but also has a disadvantage that 
there is overhead from serialization 
and deserialization of session data. This mode should be used when reliability is more important than performance. 

aspnet_regsql.exe -ssadd -d ASPState -sstype c -S (local) -U sa -P sa123

<configuration>
    <sessionstate mode="sqlserver" cookieless="false" timeout="10" 
       stateConnectionString="tcpip=127.0.0.1:4  2424" 
       sqlConnectionString="Data Source=.\SqlDataSource;User ID=userid;Password=password"/>
</configuration> 

Custom Session mode: Generally we should prefer in proc
 state server mode or 
SQL Server mode but if you need to store session data using other 
than these techniques then ASP.NET provides a custom session mode. This 
way we have to maintain everything customized even generating session 
ID, data store, and also security. 

2. Application

Application state is a server side state management technique. The date stored in application state is common for all users of that particular ASP.NET application and can be accessed anywhere in the application. It is also called application level state management. Data stored in the application should be of small size.
How to get and set a value in the application object:

Application["Count"] = Convert.ToInt32(Application["Count"]) + 1; //Set Value to The Application Object
Label1.Text = Application["Count"].ToString(); //Get Value from the Application Object

Solution:
This method worked for me,

-Stop IIS server or VS

-go to:
C:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files

-and delete all folders in this directory

-launch IIS or VS

There are various reason for this error. in the following list all may cause this problem


1.

public static ReportDocument rep = new ReportDocument();
   protected void Page_UnLoad(object sender, EventArgs e)
   {
       this.CrystalReportViewer1.Dispose();
       this.CrystalReportViewer1 = null;
       rep.Close();
       rep.Dispose();
       GC.Collect();
   }

2. crystal report assemblies installed on your machine do not reflect the assemblies you have on your web.config

3. crystal version installed on the server is different with the one you want to invoke from your site

4. application pool where your reports run is not set to LOCAL SERVICE

5. read and write permission is not enabled on your root folder

6. crystalreportviewer folder is not copied to your operating folder. 

7. lack of permission in following  directory
