Yes, I will suggest you to store data table in Session , rather than View State as you data size is quite big.
Any way you can check one of my article on view state
Beginner's Guide to View State[^]
And don't forget to read Discussion Section [ViewState Vs Session ]

Your best bet if it's big is to store the ids needed to build it, on the URL perhaps, and then get the data from the DB as needed. keeping viewstate down is a good thing, but using the session too much is also a bad move.

Hi Nishant

Session v/s Viewstate is quite a good question, but you need to consider two things before you make up your mind.

1. How long you want to retain the DataTable in Memory. i.e. if your site is hosted on shared server then you cannot hold it for more than a 5-10 mins as the services restart and the session is destroyed. So in this case the viewstate is better option. But if you are having dedicated server then opt for session.

2. Why not XML. Create a XML of datatable with unique name, write it to disk and then save the file name in ViewState. You will save both the ViewState and session memory.

Hi,

here is the code:
using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Data.SqlClient;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;

public partial class MainCategory : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
int y = Convert.ToInt32(Request.QueryString["menu_id"]);

string z = (Request.QueryString["menu_text"]);
string v1 = z.ToUpper();
v1 = v1.Replace(" ", "");
getid();

SqlConnection con = new SqlConnection("Server=.; Database=eclsc; Trusted_Connection=yes");
SqlDataAdapter sda = new SqlDataAdapter("select top 1 "+v1+".image, ID.category_name from "+v1+", ID where where parent_id='"+test1+"' ", con);
DataTable dt = new DataTable();
con.Open();
sda.Fill(dt);
DataView dview = dt.DefaultView;
DataList1.DataSource = dview;
DataList1.DataBind();
con.Close();
}

public void getid()
{
int y = Convert.ToInt32(Request.QueryString["menu_id"]);

SqlConnection con = new SqlConnection("Server=.; Database=eclsc; Trusted_Connection=yes");
SqlCommand cmd = new SqlCommand();
cmd.Connection = con;
cmd.CommandText = " select category_id from ID where menuindex='" + y + "' ";
con.Open();
string test1 = cmd.ExecuteScalar().ToString();
con.Close();
}

the error is :test1 is not in current context.I want it in page load

Its seems , you didn't understand your last answer that what other people given. Sleepy | :zzz:

just do it using View State.

protected void Page_Load(object sender, EventArgs e)<br />
{<br />
if(ViewState["TestVal"] !=null )<br />
<br />
   {<br />
    //Do Something<br />
   }<br />
   else<br />
   {<br />
    //Do Something<br />
    string test=ViewState["TestVal"]<br />
    //bla bla..... your query etc....<br />
    <br />
   }<br />
}

public void getid()
{
int y = Convert.ToInt32(Request.QueryString["menu_id"]);

SqlConnection con = new SqlConnection("Server=.; Database=eclsc; Trusted_Connection=yes");
SqlCommand cmd = new SqlCommand();
cmd.Connection = con;
cmd.CommandText = " select category_id from ID where menuindex='" + y + "' ";
con.Open();
string test1 = cmd.ExecuteScalar().ToString();
ViewState["TestVal"]=test1;
con.Close();
}

cheers,
Abhijit

This is retarded. Your page will blow up if someone puts a non number on the URL.

how to get the value of a variable defined in a method, in page load.

return the value of test1 from getid();

public string getid()
{
int y = Convert.ToInt32(Request.QueryString["menu_id"]);

SqlConnection con = new SqlConnection("Server=.; Database=eclsc; Trusted_Connection=yes");
SqlCommand cmd = new SqlCommand();
cmd.Connection = con;
cmd.CommandText = " select category_id from ID where menuindex='" + y + "' ";
con.Open();
string test1 = cmd.ExecuteScalar().ToString();
con.Close();
return test1;
}

and on page load use

string test1=getid();

SqlConnection con = new SqlConnection("Server=.; Database=eclsc; Trusted_Connection=yes");
SqlDataAdapter sda = new SqlDataAdapter("select top 1 "+v1+".image, ID.category_name from "+v1+", ID where where parent_id='"+test1+"' ", con);
DataTable dt = new DataTable();
con.Open();
sda.Fill(dt);

as simple as that

if you are trying to get value in same request then declare member as class level. if you are trying to get value after postbacks try using viewstate.
