inserting to multiple fields using a button

I have multiple textboxes in a page. How do i make them insert their values to multiple fields on multiple tables using a button.

You can just execute some SqlCommands to insert data to different tables in the Click event of a button, for example:

protected void Button2_Click(object sender, EventArgs e)
{
using (SqlConnection conn = new SqlConnection(@."Data Source=labsh96223\iori2000;Integrated Security=SSPI;Database=tempdb"))
{
conn.Open();
string insertSql = @."Insert into myTbl_1 select @.id, @.name";
SqlCommand myCommand = new SqlCommand(insertSql, conn);
myCommand.Parameters.Add("@.id", SqlDbType.Int);
myCommand.Parameters.Add("@.name", SqlDbType.VarChar, 100);
myCommand.Parameters["@.id"].Value = Int32.Parse(TextBox1.Text);
myCommand.Parameters["@.name"].Value = TextBox2.Text;
int i = myCommand.ExecuteNonQuery();
myCommand.CommandText = @."Insert into myTbl_2 select @.id, @.Description";
myCommand.Parameters.Clear();
myCommand.Parameters.Add("@.id", SqlDbType.Int);
myCommand.Parameters.Add("@.Description", SqlDbType.VarChar, 1000);
myCommand.Parameters["@.id"].Value = Int32.Parse(TextBox3.Text);
myCommand.Parameters["@.name"].Value = TextBox4.Text;
i= myCommand.ExecuteNonQuery();
//execute other commands
}
}
