I new that BindingSource's AddingNew event can handle all default value assignment, but was so frustrated that I could not find any articles/tutorials which guided me on how to use it. Although MSDN had description, but it did not have samples on how to use it. However, with few long hour searches I came to a source which enlighted me on how to use this event.
A sample code looks like this:
private void branchBindingSource_AddingNew(object sender, AddingNewEventArgs e)
{
//// Get data table view
DataView dataTableView = branchBindingSource.List as DataView;
//// Create row from view
DataRowView rowView = dataTableView.AddNew();
rowView["BranchID"] = -1;
rowView["BranchCode"] = "001";
rowView["BranchDescription"] = "002";
//// Set New row
e.NewObject = rowView;
branchBindingSource.MoveLast();
}
