First of all you need to declare a form level BackGroundWorker, and in your form constructor add a handler for it's DoWork event. Then you can simply run your above code in the DoWork event, something like this:

C#

BackgroundWorker bgw = new BackgroundWorker();

        public Form1()
        {
            InitializeComponent();
            bgw.DoWork += new DoWorkEventHandler(bgw_DoWork);
            button1.Click += new EventHandler(button1_Click);
        }

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

        void bgw_DoWork(object sender, DoWorkEventArgs e)
        {
            if(cmbSelectFileType.Text == "Text")
            {
                if (Validation())
                {
                    panel1.Enabled = false;
                    pictureBox1.Visible = true;
                    UpLoadUsingText();
                }
            }
            else if (cmbSelectFileType.Text == "Excel")
            {
                if (Validation())
                {
                    panel1.Enabled = false;
                    pictureBox1.Visible = true;
                    UpLoadUsingExcel();
                }
            }
        }

Hope this helps
