Yes, but can I close the connection before I read the data in the reader? How exactly does the reader work?

i dont know exactly how the reader works, but you need to close the reader before you close the connection, unless something has changed, i tried that once a long time ago and got an exception and have not tried it since. If ihad to guess i would think that the reader keeps the result set cached on the dbserver somwhere and uses the connection to go get whatever you tell it to go get, i think odbc works ina similar fashion, i could be and probably am wrong about some things but i have not looked into the specifics of how in a while, and when i did it was for .net 1.1 not the newer versions.

Yes.
The data reader doesn't contain the result from the database, it only reads one or a few records at a time.
Despite everything, the person most likely to be fooling you next is yourself.

you might be using the datareader which fetches the data in loop.

I'm using a treeview control.
The treeview is on a masterpage, right beside it it has the container.
The user uses the treeview to navigate to aspx pages using this masterpage.
But on each page load the treeview nodes are collapsed to original state.
I want to maintain the nodes expanded state.
How can I do that?

hi
i think that you configured the TreeView contorl's ViewState property to false.
you can change it to true.

I just want to maintain the treeview depth between requesting pages and not to go back to the expandDepth specified in TreeView property window.

hi
if you configured treeview's viewstate property to false then treeview state back to it's default through requests.
so you should change the viewstate property to true then you can maintain treeview state through requests.
if you meant anything else tell me my dear. 
bye.

The TreeView state is True.
but how can I maintain the ExpandDepht?
I want to keep the ExpandDepth not to back to its original state after each request.
Thanks,

Some pages on my site have sensitive information. If the user is on one of these pages how can I have the page redirect to the login page if there is no interaction on it, say five minutes.

You can use SesionTimeout but it will be applicable on whole site.just for few pages,you can use a timer to achieve this

When a user successfully logs into my website he is sent to the main page. From there if he clicks on the logout link on that page he goes back to the login page. When he is directed back, however, the browser uses the page in the cache. How can I tell it to reload the login page from the server instead?

Hy,
how can i find the age of a person in dd/mm/yyyy format.....if the date of birth is given..
i have written a code but it doesent find the number of days(whn the current date is less than the date of birth ex 7/11/2008 - 12/10/2008 )
my code is
string m_Str = TextBox1.Text;
int m_Y1 = DateTime.Parse(m_Str).Year;
int m_m1 = DateTime.Parse(m_Str).Month;
int m_d1 = DateTime.Parse(m_Str).Day;
int m_Y2 = DateTime.Now.Year;
int m_m2 = DateTime.Now.Month;
int m_d2 = DateTime.Now.Day;
int m_date = m_d2 - m_d1;
if (m_date < 0)
{
m_m2 = m_m2 - 1;
?????
}
int m_month = m_m2 - m_m1;
if (m_month < 0)
{
m_Y2 = m_Y2 - 1;
m_m2 = m_m2 + 12;
m_month = m_m2 - m_m1;

Sorry, what?
You're having trouble finding someone's age when their date of birth is in the future...?
And what's wrong with this:
System.DateTime birthDate = DateTime.Parse(m_Str);
System.TimeSpan diffResult = DateTime.Now.Subtract(birthDate);
Console.WriteLine("Difference in days = " + diffResult.Days);
