Try with below code: string toMatch = txtUser.Text; ListItem item = ListBox1.Items.FindByText(toMatch); if (item != null) { //found ListBox2.Items.Add(item); } or ListItem item = new ListItem(txtUser.Text); // Checking if listeitem is exist then add to Listbox2 if (ListBox1.Items.Contains(item) ){ ListBox2.Items.Add(item); }
