creating a registration page.

Is there a way you can use information that is put into a textbox to update a database?  For example: A user puts in his/her email address and inputs a password, it updates the database when they click on the register button.  This of course happens if it passes the validators. I appreciate any help I can get on this.

That helps if you are using a datagrid. However, that isn't any help as far as the text boxes.  This is a snippet of what I have so far. Where I am having problems is the code that will allow the user to click on the "register" button and update the sql database based on user input. Here is what I have so far:
 Company Contact Name:
                    <asp:TextBox ID="cocontact" runat="server" Width="247px"></asp:TextBox>
                    <br />
                    <asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server"
                        ControlToValidate="cocontact" ErrorMessage="Please Include a contact name "></asp:RequiredFieldValidator>
                    <br />
                    Company Street Address:
                    <asp:TextBox ID="costreetadd" runat="server" Width="247px"></asp:TextBox>
                    <br />
                    <br />
                    Company City:
                    <asp:TextBox ID="cocity" runat="server" Width="247px"></asp:TextBox>
                    <br />
                    <br />
                    Company State:
                    <asp:TextBox ID="costate" runat="server" Width="247px"></asp:TextBox>
                    <br />
                    <br />
                    Company Zip Code:
                    <asp:TextBox ID="cozip" runat="server" Width="247px"></asp:TextBox>
                    <br />
                    <br />
                    Company Phone:
                    <asp:TextBox ID="cophone" runat="server" Width="247px"></asp:TextBox>

I was able to figure this part out. I used a sql data source and an insert statement from there. On the button click event I put the following code:

sqldatasource1.insert().

When I run the website, I get this error:
[InvalidOperationException: Could not find control 'cologin' in ControlParameter 'loginemail'.]

I double checked this over an over again, I still was not able to come up with why this is happening. Anyone have any suggestions?

I still haven't been able to figure this one out. I am still getting the same error. I have been doing research it isn't like I am asking everyone on here to spoonfeed me the informaiton. I do appreciate the help I have gotten so far. I simply used a sql data source and dragged it on the page and configured an insert statement as was said in one of the earlier posts in this website. I am lost on this and haven't been able to find an answer.

I still haven't been able to figure this one out. The expert never got back to me. I am to the point that I know I need a data connection. I did that and I am still getting the error I noted in this post.
