I am using Combobox SelectedIndexChanged event to perform few tasks. It is working nice. But when i am closing the form, SelectedIndexChanged gets fired and i get "Object reference not set to an instance of an object." exception. My code is following-
  private void cmbProductName_SelectedIndexChanged(object sender, EventArgs e)
            Product p =(Product) cmbProductName.SelectedItem;
            RawItems = RawItem.GetEntityList(p.Id, ConnectionString);
        catch (Exception ex)
How to avoid the SelectedIndexChanged event being fired when form is closing?
