Updating of BindingSource in WinForms does not update Datasource Collection

Question

I want to display a custom collection in a DataGridView in a Windows Forms app. This custom collection implements ICollection, and IEnumerable

Answer 1

The problem is Fill Adaptor. When you load your form, the Fill is done for you. Just make sure to do a Refill and then follow up with Reset bindings post any data changes and Grid will get refreshed.

Example :

WorkTableAdapter.Insert(objData.XAttribute, "",
  objData.YAttribute,objLoanData.Amount_IsValid, DateTime.Now, DateTime.Now);
this.WorkTableAdapter.Fill(this.POCDataSet.Work);
this.WorkBindingSource.ResetBindings(false);
