Beginner :: Need help to bind the data in GridView using asp standard controls

[Riaaaa]

I m beginner for ASP.Net 2005 with C# and SQL Server 2005.

I have created the form which contains many asp standard controls on it like label,textbox,checkbox,dropdownlist,command button.
The command button used are only to execute the different queries on click event.
I have put the GridView control which is used to show the database stored related to that form.
I m using SQL DataSource control for the connection.

Now,my problem is i m not able to write the proper SQL queries which insert,delete,update or select from the GridView and Standard Controls.

In short,I have a command button set up on a form to run a SQL pass-through insert query after several field are filled in standard controls but I can't get .Please anyone could help me to provide the sample source code related to above controls used in the same form.

Thanxs
