thanks @har har.

i found solution, position cursor @ beginning of contents of textbox control, call select method , specify selection start position of 0, , selection length of 0.

private void form1_load(object sender, eventargs e)     {         textbox1.text = "hello sample application";         textbox1.select(0, 0);     } 

it show cursor position @ 0 index, it's working.
