ASP.NET Dynamic Data Web Application Table Help

Hi everyone.
 
I am new at making web applications. I am wanting to make a ASP.NET Dynamic Data Linq to SQL Web Application. I followed most of the Adventure example to get a simple table and showing up in the web browser. What I need help with is making the table in the web browser let me able to add, delete or update information from my table I made.
 
I believe you would use some triggers or stored procedures, but I have not been able to find any tutorials that can explain it to me. Just want to have some blank text boxes under each column of my table for inserting new information.
 
It would be greatly apperciated if someone could help me with this.
