Updating/Inserting is not supported by data source - sql

Question

I've been making my first ASP.NET Visual Studio website and I have just started working with databases, I've made a table and a backoffice page for me to control the content of my table.
This page follows the following rules:
-> I've added the SQLDataSource and configured.
-> I've added a gridview to see my content and configured it to my SQLDataSource, here I've added the Edit/Delete options.
-> I've added a DetailsView configured to my SWLDataSource, here I've added New option (to create new entries in my table)
My database has the id column set as primary key (data type=int; allow nulls=not checked)
Every time I try to update my data base through this backoffice page I get the following error:
Updating is not supported by data
source 'SqlDataSource1' unless
UpdateCommand is specified.
Description: An unhandled exception
occurred during the execution of the
current web request. Please review the

I could really use some help here!

The errormessage says it all : 'Updating is not supported by data source 'SqlDataSource1' unless UpdateCommand is specified.'. You have to assign sql code or the name of a stored procedure to the property UpdateCommand so that the SqlDataSource knows how to handle your update.
