I have zero experience with code behind pages....so be kind.

I would like to use it for inserting or updating code to my SQL database.  I found some code behind that looks like it will work well for my needs.  Can someone tell me how to code my main page for this? I am using a submit button and VB.

Here is URL for the code behind..

http://www.dotnetspider.com/resources/21175-Vb-net-code-insert-entered-repair-form-details-into-database.aspx

I am using code behind for my calendar popup...stolen from web also.  But that is callled from the image of a calendar on my page.

I am include some code snippet - I have the submit button there but only show 12 fields - there are probably about 60 fields that I will be writing  to my database.

Well anything that has a .Text you have to create a text box for.  also... the code you chose is a little more complicated than necessary...i think there are simpler ways to do this...VS has a lot of wizards for your convenience...  i suggest you visiting

I am not using visual studios... I am using Expression Web so no Wizards for this at least not what I have seen.

oh...ok...well still...ok...i see..well you could just take that whole page load sub and place in the code behind...also...can you provide a link to where you found this code....Usually also you load your first data view in Load...But i'm sorry...I can't proceed further...what exactly are you trying to do with this code?

The code is in the URL above.  I am going to modifiy it for my datasource and my text fields.  I want to call that code behind from my webpage. Obviously the code behind will be in a code behind file in my website..not calling it from that URL.

My question is.... How do I code my webpage to call that code behind file when I click the submit button.

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>  will make the page look to the code behind...i.e..

place this in Default2.aspx...and it tells it to look for this file for code/events of page


and is the submit button an aspnet button?

in the link you provided:

 Protected Sub LinkButton1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles LinkButton1.Click

see at the end where it says Handles...well whatever name is in front of the .Click, name your <asp:button id ="LinkButton1... or <asp:LinkButton id= "LinkButton1"   or you can change the Name in front of the .Click to reflect the name you have already chose...

if it's an <input type = submit.... then

i.e <input type="submit" id="submitter" runat="server" onserverclick="clickMe"...then

or you could just add handles submitter.ServerClick
