Show an animated loading GIF image on a Windows Form (c#)

Last week I got a problem to show the loading progress in the windows form. I wish to show the ajax loading image. For this I found a easy method "backgroundWorker".

BackgroundWorker class provides an easy way to run time-consuming operations on a background thread. Here i just explain to show the gif image with the help of BackgroundWorker class.

using System;
using System.Data;
using System.Drawing;
using System.Windows.Forms;
using System.Data.OleDb;
using System.Text;

namespace AirtelCustomerDts
{
    public partial class Search : Form
    {
        DataTable DT;
        public Search()
        {
            InitializeComponent();
            ShowSearchTextbox();
        }
        private void btnSearch_Click(object sender, EventArgs e)
        {
           try
            {
                picLoder.Visible = true;
                this.backgroundWorker1.RunWorkerAsync();
                this.btnSearch.Enabled = false;
            }
            catch (Exception ex)
            {
                writelogfile.WriteFile("btnSearch_Click : ", ex.Message);
            }
        }
        private void backgroundWorker1_DoWork(object sender, System.ComponentModel.DoWorkEventArgs e)
        {
                DT = SearchDts().Tables[0];
        }

        private void backgroundWorker1_RunWorkerCompleted(object sender, System.ComponentModel.RunWorkerCompletedEventArgs e)
        {
            dgvSearchResult.DataSource = DT;
            this.picLoder.Visible = false;
        }
