Hi Tomasz,
Getting the row deletion notification is easy. You may use
BindingSource.ListChanged event for this task. In this event, you may check
if the current list change type is ListChangedType.ItemDeleted. The code
snippet below demonstrates the logic:
private void bindingSource1_ListChanged(object sender, ListChangedEventArgs
e)
{
if (e.ListChangedType == ListChangedType.ItemDeleted)
{
}
}
However, to get the current deleted rows, there is no simple and easy way.
BindingSource.ListChanged is a completed event which fires after the row
deletion is done. When this event is firing, the row is already deleted
from the DataView. By default, the DataView will filter out these deleted
rows with DataView.RowStateFilter property.
The workarounds we have are:
1. If you are binding to the DataTable/DataSet, you may use
DataTable.RowDeleting event to get the deletion notification. And the
DataRowChangeEventArgs.Row will point to the current deleting row.
2. You have to catch all the deletion operations at various UI controls ,
such as DataGridView, BindingNavigator etc.. and find out the current
deleting rows
Hope this helps.
Best regards,
Jeffrey Tan
