Finally i found the problem i was using metro framework and all your solutions will not work with metroTextBox, and all your solutions will work with normal textBox in load , show , visibility_change ,events, even the tab index = 0 is valid.

   // private void Form1_VisibleChanged(object sender, EventArgs e)
   // private void Form1__Shown(object sender, EventArgs e)
    private void Form1_Load(object sender, EventArgs e)
    {

        textBox1.Select();
        this.ActiveControl=textBox1;
        textBox1.Focus();
    }
