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?

1
2
3
4

actuallly it shows the data in the following way
1.00

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?");
}
}
}
}

Read through the scenario.
client A wants to read files from another client B present in the same network. But this reading should be done through a ASP.NET web application . In other words a client should be able to read a text file present on another client in the same network.
This scenario would be applicable in an intranet application. The thing to note is that the path of client B would be present in the server. The client A would pick the path from the server and navigate automatically to client B, hunt down the necessary folder and read the text files and store the necessary data in a database.

It's not possible with ASP.NET, because it is executes at the server side and returns HTML output. It can't access other machines and take files from there.

Not possible.
Try with any Windows Service/Application to do that. Use .NET for that

Only if all your clients have shared their C: drives to the network... (not recommended, just in case you're wondering).

alert(document.getElementById('yourtablename').innerHTML);
