I was wondering how you could encrypt/decrypt your querystring in a simple asp.net page? some values need to be passed between different pages but the querystring cannot be changed or read.
Some say httphandles could be the solution for this.
MORE BACKGROUND INFO:
this is the problem, sometimes the sessions disappear without any reason (well there must be one but I don't know it yet). I've looked into the possible reasons but nothing that could cause it is happening.
Therefore I cannot rely on it anymore. The cookie solution is a possibility but it will be more work to implement than simply using the querystring. The url can be copied at any time just not changed!

We do have a search page for customers which returns a list of data from a table.
Once we select on an item it should redirect to another page with customerId as a querystring parameter..
Now the problem is we have to save all the customerIds and need to send them to display page..and need to select next one once they done with previous one without going to the search page again..
Example:
if they got 10 customers in the search page then we need to send all 10 ids to display page by starting display of firstone and once they select next button on display page they have to move on to the next cutomer from that list..if they reached the end of list they have to start again from the first...we need to avoid the user going to the search page for each customer every time...

View 1 RepliesThe following code works well as long as I pass a querystring value to the datalist.
Private Sub BindGrid()
Dim id As Integer = Integer.Parse(Context.Request.QueryString("id"))
Dim strConnString As String = ConfigurationManager.ConnectionStrings("Conn").ConnectionString
Using con As New SqlConnection(strConnString)
Using cmd As New SqlCommand()
cmd.CommandText = "select Id, Name from tblFiles where Id=@Id"
[Code] ......
However, the page errors with the message "Value cannot be null." if I don't pass a value. I know that DataList does not have an EmptyItem Property like a Gridview control. I do not want the page to error if I don't pass a value. Need info to deal with empty values in a datalist.
Most websites have pointed me to this code to use:
<FooterTemplate>
<asp:Label ID="lblEmpty" Text="No Result" runat="server"
Visible='<%#boolean.parse(([b]list[/b].Items.Count=0).ToString())%>'>
</asp:Label>
</FooterTemplate>
The 'list' throws an error. The error is "Too few type arguments to 'System.COllections.Generic.List". I am not sure if the code is written in C# and that is what is causing the error. It seems that it should work but I can not figure out the 'list' error.
I have two asp page first is login page. I enter username and password then after submit click goes second page their is a logout option. then thr URL of second page is copy and paste in another browser then it will second page it is not logout,I want to after paste URL it goes Login page.
