c# - Delete list item with BindingNavigator, not correct item -

i use bindingnavigator delete items products list, via datagridview. (the methodcall main.deleteproduct() calls repository delete database).

i need improve code of ..deleteitem_click event. when click on cell/or row, , delete button (bindingnavigator), never deletes row. deletes row below, or if it's last row, row above, , if 1 row, null cast. shouldn't bindingsource.current same item currentrow of datagridview?

also, way i'm casting current item using bindingsource way? appretiate better code suggestion if have.

cheers!

 public partial class form1 : form {           private mainbl main = new mainbl();      private   list<product> products = new list<product>      private void form1_load(object sender, eventargs e)     {          bsproducts.datasource = products;         // bindingsource         bnproducts.bindingsource = bsproducts;    // bindingnavigator         datagridview1.datasource = bsproducts;    //     }      private void bindingnavigatordeleteitem_click(object sender, eventargs e)     {          product product = (product)bsproducts.current;         // putting breakpoint here, shows identity property not same        // row selected in datagridview.           main.deleteproduct(product);      } 

a better solution intercept/remove binding navigator's delete event, , handle deletion manually.

go binding navigator; bring properties in properties window. find deleteitem property (under "items" category), , set "(none)".

now can code deletion functionality in click event of delete button in associated toolbar. code in previous answer work - can correct "current" item. can add confirmation check ("are sure?") here if required.

of course, not forget remove item collection bindingsource bound (or refresh data).
