In the load event of the page you can check for the session and then if it is not available then user should be redirected to login page.

Hi,
Thats the question of logic.
First you should put an item in dropdownlist which can be used to indicate that no value is selected from the dropdownlist such as a "Other".
Then you should check for the value of dropdownlist in the form collection if it is "Other" or not.
It it is "Other" then you should go for the textbox value.
The code might be like following.
String strActor;
strActor= Request.Form["ddlActor"];
if(strMovieName == "Other")
{
strActor= Request.Form("txtActor");
}
The same thing you can implement for other stuff also.
I hope this will help you.
Thanks and Regards,

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.

Thanks for answer..so static variable will be maintained at server during subsequent page requests..right?

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.
