Hi friends,
If I am making my some member variable of a class as a static(say int i),then at each Page Postback i m able to manipulate(say increment) the previous value of i.My Question is whether by making member as a static are we making it to be remember by server during subsequent page requests..if so then how http is stateless..
Warm Regards,
Rahul Agarwal

Hi,
Remember that static members belongs to a class. Therefore whatever you do to it in a class will be remembered for the time that this application is running in it's own session (will not influence another user). But the problem is it will be reset when the application close.

Thanks..But I tried something like this..
static int i;
protected void Page_Load(object sender, EventArgs e){}protected void Button1_Click(object sender, EventArgs e)
{ i=i+1;
TextBox1.Text=i.ToString();
}
For each Button Click event, the value of "i" is incremented and displayed in the TextBox.
I have clicked the button 5 times and the text box shows 5 in it.
At this moment,when I opened another browse , copy - paste the same url
and I tried to click the button, it shows "6" in it.
Then why it working when i am opening the page in new browser window..My question is whether making it static will make it remember at server during subsequent page postbacks or not?
Warm Regards,
Rahul

according to me value of static variables is maintained at server till that variable is not assigned null value or u need to call the destructor to relase the memory occupied by that variable.Else server will maintain the varaibles value even if u close the application from client end.

Http is stateless, ASP.NET is not.
Http is the communication protocol that helps the browser and the web server talk and exchange HTML. Your ASP.NET website is also an application, but it runs inside an application domain within IIS.

Do you have a Web.sitemap file at the root level of your web site virtual folder ?
This must be a valid XML file with your menu description.

Hi all
In a asp.net form i have many controls. So i want user to fill all fields with proper data so i want to validate those controls. I tried writing a code like this but it didn't work
If TxtFname.Text = "" Then
MsgBox("Enter The First Name")
End If
Server Error in '/WebApplication2' Application.
--------------------------------------------------------------------------------
It is invalid to show a modal dialog or form when the application is not running in UserInteractive mode. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application
Can any tell me the code that i need to implement here. like fields should not be empty, and in text boxes user should not be able to enter numeric value and vice versa.

hi frnd,
The best to validate the textbox in web application is use
JAVAScript
just try out following code in soure
type in
after <title>
function ClickMe()
{
if document.getElementById("txtFName").value==""
{
alert("Please Enter FName");
return false;
}
}
Call this method on click

You can use validation controls provided by .Net or can also use javascript for that purpose. Normal validation should be done on client side.
