ListView Binding event

Hi,

I come back with a question which was answered in thread below, but for some reason we must use ListView (convert from VWG) https://wisej.com/support/question/listview-binding-event

Actualy we use BindingList for ListView, but it looks like something is wrong in  Wisej. ListItem_PropertyChanged  sends event with newIndex, and oldIndex= -1, but Wisej use only index =-1.

Could you please take a look again? Thank you for your help.

Hi,

thank you for your help. listView.Fill(dataSource) solves many our simple forms. We will move some others to DatGridView. Will you fix the problem with NewIndex?

Best regards,

    Thanks, I see the OldIndex being -1 and we should use NewIndex instead, But it will not change much in your app. Everything is bound to the same source and a change in the text of the control will recreate the row, recreate the control, and you lose the focus. You should use a DataGridView instead of creating potentially hundreds of TextBox controls (this was one of the many wrong things that VWG did); if you really want to use it that way use listView,Fill(dataSource) instead.
