Karan please once follow below process: Step-(01.) From where you calling your form there take a List. public List ListBoxItems { get; set; } ListBoxItems = new List ( ); Step-(02.) Before open form check that LIST count. If LIST count > 0 then through loop add items from LIST to listbox. Form1 frm = new Form1(); if(ListBoxItems.Count > 0) { // Add item to your listbox2 } Step-(03.) On your Form1 when you are adding items to listbox2 from listbox1 then also add items to LIST - ListBoxItems If this is helpful for you then please accept my Answer .
