Using .Net 2.0...
When a user logs in to my site, I set a few session variables with his user info. When the user clicks "logout", a logout page is loaded that clears the session variables completely (with Session.Clear();) and redirects to Default.aspx. However, after logging out, if the user manually types in the url for a members-only page, it appears to still think they're logged in. It's almost like the browser has cached the members-only page.
Did I explain that okay?
Is there a way to clear specific pages from the cache?

Use following line in the Page Init/Load of the specific page you want to remove from the Cache,
Response.Cache.SetCacheability(HttpCacheability.ServerAndNoCache);
HttpCacheability also has few more enumerations.

I was actually looking for something that I coudl use at the point the user logs out, like being able to tell the browser to remove certain pages from the cache.
I've already tried the thing you suggested (in Page_Load of the given pages), and it's too heavy handed (I need to keep some variables around that can't be put in the Session vars.

Are you sure that session is cleared ? I had the same issue. When URL's are typed straight, it loaded the page. But it will redirect when we hit F5. Is it redirecting for you ? Disabling caching methods didn't worked for me. I think it's browser behavior and we can't control much.

Also try with Session.Abandon(). I think Session.Clear() clears the values, but the session instance would be still active.

Presently not available in ASP.NET.

No other way. I have developed websites which are using HttpCacheability to pages which are to be authenticated. I suggest you to not to use Sessions widely, particularly heavy objects like DataTable....

In other words you want to make a static utility class
public static class Utility
{
public static void MyUtilityMethod()
{
}
}

You can't declare an instance member inside a static class, I guess ?

Oops! I've corrected it.

Put your classes in app_code(ASP.NET 2.0 or later) directory which can be accessible from anywhere in the application.

Check whether you have assigned value in the SortExpression of each BoundColumns.
SortExpression might be the column name which is use to sort the GridView.

I haven`t explicitly specified the sortexpression in the .aspx page.
for your reference i m giving you the code
Sub FillGrid()
cmd = New SqlCommand
cmd.Connection = con
cmd.CommandText = "List_Party_Info"
cmd.CommandType = CommandType.StoredProcedure
sda = New SqlDataAdapter
sda.SelectCommand = cmd
ds = New DataSet
sda.Fill(ds)
CustGrid.DataSource = ds
CustGrid.DataBind()
Session("Data") = ds
ValidateGrid()
End Sub
above code is used for binding the grid
and the following is the sort command
Private Sub CustGrid_SortCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridSortCommandEventArgs) Handles CustGrid.SortCommand
Dim ds1 As DataSet = CType(Session("Data"), DataSet)
Dim dv As DataView = ds1.Tables(0).DefaultView
dv.Sort = e.SortExpression
FillGrid()
End Sub
Html Code
<asp:datagrid id="CustGrid" CssClass="datagrid" Runat="server" cellpadding="4" bordercolor="#EFEFEF"
AutoGenerateColumns="False" AllowSorting="True">
<AlternatingItemStyle CssClass="datagrid_row"></AlternatingItemStyle>
<ItemStyle CssClass="datagrid_row1"></ItemStyle>
<HeaderStyle CssClass="datagrid_heading"></HeaderStyle>
<Columns>
<asp:BoundColumn Visible="False" DataField="PARTY_CODE" HeaderText="Code"></asp:BoundColumn>
<asp:BoundColumn DataField="_XXXX" HeaderText="Bill Unit"></asp:BoundColumn>
<asp:BoundColumn DataField="YYYY" HeaderText="Name"></asp:BoundColumn>
<asp:BoundColumn DataField="ZZZZZZ" HeaderText="Role"></asp:BoundColumn>
</Columns>
<PagerStyle Mode="NumericPages"></PagerStyle>
</asp:datagrid>
but this event doesn`t fire..Whate can be the problem???

As I already told you, SortExpression is the problem. Please define SortExpression for the BoundColumns to which you want Sort option.

You should handle the Sorting event of the GridView. I am sure, you are not handling that event.
