Button to call another Aspx page

[=?Utf-8?B?ZWdzZGFy?=]

Hello, i have implemented a button in some other pages that calls another
one, the problem is that everytime I hit the button he goes for the postback
code and I already disable that part. this is my code:

<%@ Page Language="VB" MasterPageFile="~/MasterPage.master" Title="SIP ::
Nichos de Mercado" %>
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.OleDb" %>

<script runat="server">
Sub Page_Load(ByVal obj As Object, ByVal e As EventArgs)
If IsPostBack() Then
Dim objConn As New
OleDbConnection("Provider=SQLNCLI;Server=db2fx981\ comware;Database=SIP;Trusted_Connection=yes;")
objConn.Open()
Dim sSQL, Resul As String
sSQL = "Insert into Nicho (Descripcion) values ('" &
Descripcion.Text & "')"
Dim objCmd As New OleDbCommand(sSQL, objConn)

Resul = objCmd.ExecuteNonQuery
If Resul Then
LblSaved.Visible = True
End If
End If
End Sub

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As
System.EventArgs)
Response.Redirect("Nichos_con.aspx")
End Sub
</script>

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder2"
Runat="Server">
<span style="font-size: 24pt">Nichos de Mercado<br />
<br />
</span><span style="font-size: 11pt; font-family: Tahoma">Por favor

</span>

The button is Button2, how can I solve this?

You are obviously using VB.NET based on your code. However, I am noticing
that you are assigning eventhandlers to your Buttons using the OnClick
attribute rather than the Handles clause (which is the preferred way to do
it in VB.NET). Although either one should work, and I will admit that I did
not actually test your code, try the following:

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Button1.Click, Button2.Click
Response.Redirect("Nichos_con.aspx")
End Sub

If you use the above code you can remove the OnClick attribute from your
Button tags (although it shouldn't hurt anything if you don't). See if it
does anything different with the above code. Also, I am getting the
impression that you have all your code in one file (is this correct?). It is
considered better practice, and definitely more organized, to use the
following three files (which is how Visual Studio 2005+ does it by default):

*.aspx
*.aspx.designer.vb (this file is automatically generated when you add a
control to *.aspx)
*.aspx.vb

I would suggest taking this into account. Good Luck!

the onload event always runs before the click event. unlike a winform
app, in asp.net the full page processing cycle happens on the first hit
to the and every postback (any server callback).
