Add a Background Worker and your code should (or could) end up looking something like this:

C#

public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
        {
            //Do NOT (ever) refer to form controls from this method
            //Keep it self contained

            //Add your background code
            //In your case it's your "btnsave_Click" method code, just check you aren't referring back to objects owned by the form thread:

            //using (SqlConnection condatabase = new SqlConnection(constr))
            //{
                //string FileSaveUri = @"ftp://111.111.111.111/httpdocs/uploadpic/";

                //string ftpUser = "sa";
                //string ftpPassWord = "111";
                //Stream requestStream = null;
                //Stream fileStream = null;
                //FtpWebResponse uploadResponse = null;

                //if (FileUpload.PostedFile != null)
                //{
                    //etc.

            //As you pass through each loop in your long runtime method do something like this
            backgroundWorker1.ReportProgress(Convert.ToInt32((countsofar / totalofthingstodo) * 100));
        }

        private void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e)
        {
            //Only ever refer to form controls from this method
            progressBar1.Value = e.ProgressPercentage;
        }

        private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
        {
            progressBar1.Value = progressBar1.Minimum;
        }

        private void button1_Click(object sender, EventArgs e)
        {
            backgroundWorker1.RunWorkerAsync();
        }
    }

For the above to work the BackgroundWorker must have WorkerReportsProgress set to True.

If you can't calculate the percentage progress then make the progressBar a Marquee (Style = Marquee) and don't report progress, just have it default to disabled (Enabled = False), enable it at the start of the job to be done and disable it in the backgroundWorker1_RunWorkerCompleted method.
