C# BindingSource.AddingNew is never called?
- by msfanboy
Hello,
BindingSource.AddingNew is never called when I leave the cell of my datagrid.
The DataGrid has as datasource the BindingSource which again has a "List" of "Customer".
What does the BindingSource need to create a new Customer object and add it to the underlying ICustomerList ?
Of course a interface has no constructor...
Thats the Exception I get:
System.MissingMethodException: The constcructor for the type "SAT.EnCoDe.Administration.ICustomer" was not found.
