Types of state management

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

Client side state management are as below:

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

Server side state management are as below

1. Session
   
2. Application

Lets see all some of the state with example:

Hidden Field

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

 if (HiddenField1.Value != null)
   {
    int val= Convert.ToInt32(HiddenField1.Value) + 1;
    HiddenField1.Value = val.ToString();
    Label1.Text = val.ToString();
   }

ViewState

protected void PageLoad(object sender, EventArgs e)
{
    if (IsPostBack)
    {
        if (ViewState["count"] != null)
        {
            int ViewstateVal = Convert.ToInt32(ViewState["count"]) + 1;
            Label1.Text = ViewstateVal.ToString();
            ViewState["count"]=ViewstateVal.ToString();
        }
        else
        {
            ViewState["count"] = "1";
        }
    }
}
protected void Button1Click(object sender, EventArgs e)
{
       Label1.Text=ViewState["count"].ToString();
}

Session

 Session["Count"] = 0;

Application

Application["Count"] = Convert.ToInt32(Application["Count"]) + 1; //Set Value to The Application Object

Label1.Text = Application["Count"].ToString(); //Get Value from the Application Object
