If you are filling the GridView at Page Load, inside
<br />
if not ispostback<br />
block that is the problem.
call the function outside the if block..
Copy and paste is a design error

Remove the coding from the RowDataBound and add following at page load
and try
For i As Integer = 2 To 19
Dim btn As New Button
AddHandler btn.Click, AddressOf click
btn.ID = i
btn.Text = GridView1.HeaderRow.Cells(i).Text
btn.EnableViewState = True
btn.CausesValidation = False
GridView1.HeaderRow.Cells(i).Controls.Add(btn)
Next
Copy and paste is a design error

You have created an event called sub click but when does that get assigned to the button?

I assigned at RowDatabound Event of gridview.
Protected Sub grdPoint_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles grdPoint.RowDataBound
If e.Row.RowType = DataControlRowType.Header Then
For i As Integer = 9 To 20
Dim btn As New Button
AddHandler btn.Click, AddressOf click
btn.ID = i
btn.Text = e.Row.Cells(i).Text
btn.EnableViewState = True
btn.CausesValidation = False
e.Row.Cells(i).Controls.Add(btn)
Next
End If
End Sub
Is it wrong? I don't know where to assigned.
Thank you all for answers

Well you have created the button at runtime in your row data bound event.
But how does the button know which onclick event to use?
Either you have done it wrong or I am confused as to what you have done. 
I think you need to add this when your button is created:
btn.Click += new EventHandler(sub_Click);

No .netman, what he doing is right, It is VB.net way.
The problem is, he is creating the button on the fly.
So when he click on the button it will automatically erased, as HTTP is stateless.

So do you need each item selected to be inserted as a new record ? Then, iterate the listbox items, pass current item to the parameter, insert it to the DB. Continue this once you insert all the selected items.

Hi see thi is my code:
SqlCmd.Parameters.Add("@User", SqlDbType.VarChar, 500);
SqlCmd.Parameters["@User"].Direction = ParameterDirection.Input;
SqlCmd.Parameters["@User"].Value = myCodes.Trim();
SqlCmd.Parameters.Add("@FromDate", SqlDbType.DateTime);
SqlCmd.Parameters["@FromDate"].Direction = ParameterDirection.Input;
SqlCmd.Parameters.Add("@ToDate", SqlDbType.DateTime);
SqlCmd.Parameters["@ToDate"].Direction = ParameterDirection.Input;
That mycodes value contained, values like this 'Admin','User'
Now how i can check in my stored procedure those records?,

In the Stored Proceedure(SP) You have to check with IN i.e.
Select col1,col2,col3 from tbltest where col1 IN(@User)
Where @User is the variable in which you are retrieving the values wich are passed to the SP
Note:Do you want to Achieve this...if not what you want to get the Out put

I have seen different behaviors for this. AFAIK, session will be available on the new window if it's opener window has session. I mean if you open browser by clicking on it's exe, session won't be shared . Session would be shared if the new window is opened by another window which has session. I have seen Firefox sharing session across tabs.

No. Application variables are available long time on the server. It's not user specific. So you will get it everywhere. Cache also will be available to all the browser instances.
Static (shared) variables stay alive in the memory till application domain unloads. So you will get this too in multiple browser instances.

Hi,
A session will be available as long as that user is using the site. No matter the page. So it’s clear that your session is available. By default, session variables are stored in memory. What I suggest you is, first in your web site find what is the setting you have given for the session state mode. It should be “InProc” to store the session in the memory. This could be found in Web.Config.
<sessionState mode="InProc"></sessionState>
Thx,
Gayani

I have to write a classic ASP page.I have a page which has a html table with some row , each row has some controls with several textboxes and 3 select controls(dropdownlist). At table's below, there is a Add button to add new row. When click on Add button, the new row will be added(with full of textboxes and select controls as same to other rows, and they have the same ID, too). What I wanna do is after selected an item from the first dropdownlist, data will be loaded from server and filled in the second dropdownlist on the same row, and after selected an item from the second one, data will be loaded form server to fill in the third one. I wonder after select an item from the first dropdownlist, I need to reload page to load data and fill the second one, and if I have some rows already has been filled data in textbox control etc will be lost. To resolve it, I've tried to use AJAX technology but It didn't work with IE though that worked with Firefox. Please help me to resolve this problem? If you can show me code better.
