C# and Database: How to Insert New record and save it

[engineer]

Dear All,

I am a very much new to C#. Today I developed my first database application using c#.

I am doing this to bind records:

txtLastName.DataBindings.Add("text", myds, "pm.last_name");

To move to next record(clicking next button):


CurrencyManager cm = (CurrencyManager)this.BindingContext[myds, "pm"];
if (cm.Position < cm.Count - 1)
{
cm.Position++;
}

else

MessageBox.Show("End of records", "my application", MessageBoxButtons.OK, MessageBoxIcon.Information);


and so on.

I have completed the record navigation functionality(FirstRecord, LastRecord, Next, Previous).

Problem:

I don't know how can I insert a new record and save it.
Please guide me in the above mentioned application.

Also recommend a good tuturial+example on web.

Thanks
