your subject line says 'remove sessions with Javascript'. For your kind information - Javascript runs on the Client and Session is a server Object.

yes,, i know that,, but how can i clear the sessions while sign out.. my sign out menu is on script..based

You need to do the following in the server-end. call Session.Abandon() Method to cancel the session followed by Session.Clear() method to clear all the values from Session State.

use Javascript to AJAX off to the server, then Session.Abandon()....

Hi,
for what purpose you want to do this ?
If u want to bind with Gridview then you can add datasource.

This is like saying "I need to write a computer program, but I don't want to use any programming languages". Why do you need this ?

dear frnd,
You can assign values from database to list(arraylist,generic list) but you should use atleast datareader to fetch data from database.
They laugh at me; they think I’m different. I laugh at them, ‘coz they are all same!!

simple - you need to regularly poll for new messages and send them back down. AJAX is driven by the client, you still need the client to send a message in order to send something back

Hi..

public event System.EventHandler Hello;
//in Button_click event
this.Hello(this, new EventArgs());
//in default.aspx.cs
protected MyControl MyControl1;
//in page_Load
this.MyControl.Hello +=new
EventHandler(MyControl_Hello);
//after Page_load
private void MyControl_Hello(object sender, EventArgs e)
{
Response.Write("welcome");
}
----------------------------------------------------------------------------
i am able to print "welcome" in 1.1 version.Above code is working fine.but in 2.o its not working.i need this in 2.0.plz anyone help me.....................

Seems ok. But if you are not using "EventArgs e" you pass null instead of "new EventArgs();".
and on the other hand i think it is better to initialize event handlers in OnInit instead of Page_Load..
What do you think guys?
|
|
|
|
|
what you told is exactly correct.bcoz i got error
object ref is not set to an instance of an object.but i am not getting how to handle it.i thought u hav a good knowledge on this topic.plz help me...(wats the code i need to write)

//in MyControl.ascx.cs
public event System.EventHandler Hello;
//in Button_click event
///I suggest:
if(this.Hello != null) this.Hello(this, null);
//in default.aspx.cs
protected MyControl MyControl1;
//in page_Load XX
///override OnInit
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
this.MyControl.Hello +=new
EventHandler(MyControl_Hello);
}
//after Page_load
private void MyControl_Hello(object sender, EventArgs e)
{
//this is not a good way put a label and assing your value to it
Response.Write("welcome");
}

Response.Write( "<script language='JavaScript'>" +

RegisterClientScriptBlock is better, and you didn't show him how to hook the call into his click event, either.
