you can try passing form1 parameter when creating form2.

private void textbox1_click(object sender, eventargs e)  {     frmcustomer customer = new frmcustomer(this); // represents form1                customer.showdialog(); } 

then on form2

private form1 frm_1; public form2(form1 frm) {     initializecomponent();     frm_1 = frm; }  private void datagridview1_celldoubleclick(object sender,datagridviewcelleventargs e) {    string name =  datagridview1.currentrow.cells["clmname"].value.tostring();    frm_1.txtcustomer.text = name;    this.close();  } 

this work.
