Hi Hanifuk ,
first you must create an overloaded constructor in form2 and a global object of form1 , your already existing default constructor is :

public Form2()
{
     InitializeComponent();
}

The global object and the overloaded constructor code will be :

public static Form1 Frm1 = new Form1();
public Form2(Form1 form)
{
     InitializeComponent();
     Frm1 = form;
}

Now you can set your control in form1 ''s modifier to public .

Then in the click add button event you will insert this code for opening form2 :

Form2 Frm2 =new Form2(this);
Frm2.show();

now in the form2 code you can update your control in form1.

I Hope this help you ,
Good luck

Here is example how you can send data to main form
