here is what I did

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:StringConnection %>" DeleteCommand="DELETE FROM [accountInfo] WHERE [username] = @username" InsertCommand="INSERT INTO [accountInfo] ([username], [firstName], [lastName], [DOB], [email], [password], [creditCardNameHolder], [creditCardNumber], [country], [city], [zipCode], [mobileNo]) VALUES (@username, @firstName, @lastName, @DOB, @email, @password, @creditCardNameHolder, @creditCardNumber, @country, @city, @zipCode, @mobileNo)" ProviderName="<%$ ConnectionStrings:FlightConnection.ProviderName %>" SelectCommand="SELECT * FROM [accountInfo]" UpdateCommand="UPDATE [accountInfo] SET [firstName] = @firstName, [lastName] = @lastName, [DOB] = @DOB, [email] = @email, [password] = @password, [creditCardNameHolder] = @creditCardNameHolder, [creditCardNumber] = @creditCardNumber, [country] = @country, [city] = @city, [zipCode] = @zipCode, [mobileNo] = @mobileNo WHERE [username] = @username">

but I don't know why it not working

The code you provided looks incomplete. There should be another function called:

protected void Page_Load(object sender, EventArgs e){};

This looks wrong to me:

Updatecmd.Parameters.Add("@username", SqlDbType.NChar);

Instead of this:

Updatecmd.Parameters.Add("@username", SqlDbType.NChar);

It should look like this:

Updatecmd.Parameters.AddWithValue("@username", username);

The reason is because you establish the username as

string username = lblUserName.Text.Trim();

So it should be username not SqlDbType.NChar:

Updatecmd.Parameters.AddWithValue("@username", username);

You have alot of minor errors.
