hello friends,
I have used the global static members in .cs like below
public static DataTable dt=new DataTable();
I have adding some dynamic columns and rows in above DataTable Object.
The problem arises , when i login into another machine and access same page the content of the datatable is added in both Pages. When I modify
any column respectively the changes shown on different machine.
I want to know that how can i overcome this problem, or how can i lock the public static members in asp.net.
Please if anyone know solution the send as soon as possible....
thank you.

static variables will have a life time till the application domain unloads. This is why you are getting same results on both machines. If you could tell us what you are trying to do, we will have some better suggestions.

I know about the scope of static variable, consider the following code i thing u understand that what i need
//Declare on Top
public static DataTable dt = new DataTable();
//on page load
{
dt.Columns.Add("HName");
dt.Columns.Add("fee_type");
dt.Columns.Add("fee");
dt.Columns.Add("disc");
dt.Columns.Add("net");
}
//DataList itemCommand Event
protected void drphead_item(object source, DataListCommandEventArgs e)
{
if (e.CommandName == "add")
{
lblerror.Visible = false;
DataRow dr = dt.NewRow();
LinkButton lb = new LinkButton();
lb = (LinkButton)e.Item.FindControl("LinkButton1");
lb.Enabled = false;
dr[0] = lb.Text;
dr[1] = "Yearly";
dr[2] = 0.00;
dr[3] = 0.00;
dr[4] = 0.00;
dt.Rows.Add(dr);
dlFeeHead.DataSource = dt;
dlFeeHead.DataBind();
}
Every time when user clcik on linkbutton (which is into the datalist control) accordingly the new DataRow is created it run perfactly, but the problem is occured when application run on two or more machine which i explained before....
If u have some solution then please reply thnks in advance....

Well, that's what static MEANS. Why are you making it static ?

I'd suggest reading a book on C#. Your code is doing exactly what you're asking it to do.

I don't see what the problem is. If you make it static, it's the same for all pages. That's what static means. Why are you using static and what is your specific problem ?

You can use setTimeout function in javascript.
try this script
function ShowToolTip(con)
{
document.getElementById("img_tool").src =con.src.replace("SmallPic","BigPic");
document.getElementById("div_img").style.left = event.clientX ;
document.getElementById("div_img").style.top = event.clientY ;
document.getElementById("div_img").style.zIndex = "0";
setTimeout("Loading()",1000);
}
function Loading()
{
document.getElementById("div_img").style.visibility = "visible";
}

yes dear u can use javascript when u use UpdatePanel
in update panel some time document.getelementById("") is working properly.
U can use the javascript with ClientControl Id.
Simple add attibute in your codebehind file and passes ClientId control to the javascript like below;
.cs
Button1.Attribute.Add("onclick","javascript : return JSscript("+TextBox1.ClientID+");");
on javascripting
function JSscript(ctrlID)
{
ctrlID.focus();
return false;
}
I hope it will work for u ...

What do you mean ? Session will be created on the server where you host application.
|
|
|
|
|
But the session will be created in system not created on the server...
i want to create the session for server help me....

Session will be on server always. You miss the concepts. Please take a good book and learn.

This person always posts silly questions.
He needs to learn how asp.net works.

Session will be created on web server where you have hosted your application

You may use Ping command to check if the mail server is down or not.
Then, depending upon the outcome, you can decide what to do.
