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 ?

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

The problem is the datagrid headers have not become clickable even afer i have made allow sorting=true.They become clickable only if i make autogenerate columns=true. What can be the problem????

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.

How are you accessing the session on the client side?
|
|
|
|
|
|
This is not on the client side - still server side code. Where do you set up your session_name variable? Is there any other information with the exception?

hi,
I have this problem, when I work on my project at work, I usually modify in the xsd file in Visual Studio 2005. I add new stored procedures and stuff like that and they are reflected normally in the database on Sql server.
but when I try to continue my work at home, I fail to refresh my database on my sql server on my home machine, according to the new modified xsd file. I don't want to copy the database from my work pc to my home pc. They both have the same name. So I usually expect it'll work ok and the sql server would detect the changes I made and refresh the database accordingly..how do I manage to do that?
I need to know, cause that would be important when I deploy my web application afterwards..I don't want to take a copy of the database on the server and update on it?
Can someone help?

in my database there is a numeric type of column , there in the tabe it shows the values in the following format
1
2
3
4
now when i switch over to the crystal reports , the cross tab crystal reports , that numeric field prevents me to format(when i right click o it, if it is a cross tab).
actuallly it shows the data in the following way
1.00
2.00
3.00
4.00
i think i can use the formula fields , can somebody tell me how to use that to strip off the .00 part, or any alternate?

Say u have a button , that propagates u from one page to another, on the form load add the attributes for the onclick function, and write the function in the java scrpt , which will confirm from u , as u have already done before

Hi
Use window.onbeforeunload in java script
var flag =0;
var needToConfirm = true;
window.onbeforeunload = confirmExit;
function confirmExit()
{
if (needToConfirm)
{
// check to see if any changes to the data entry fields have been made
var elem = document.getElementById('<%= txtName.ClientID %>');
if(flag == 0 )
{
if(elem !=null)
{
return ("are you want to leave?");
}
}
}
}
